Biomass production and nutrient cycling studies were carried out in a young teak (Tectona grandis L. f.) plantation of five year old (density 2,500 trees ha-1). The trees attained an average girth and height of 23.1cm and 7.6m, respectively and the above ground biomass (agb) amounted to 76.9 t/ha, of which stem wood contributed 60%. The percentage of ischolar_main to agb was 20.5%. Investigations on nutrient content in the standing crop have shown that the per cent concentration of nitrogen (N), phosphorous (P), potassium (K), calcium (Ca) and magnesium (Mg) were highest in leaf. But on unit area basis, wood accumulated the major portion (39 to 60%) of all nutrients. Among the nutrients, maximum accumulation was accounted for Ca (1,619 kg ha-1) and the minimum for P (178 kg ha-1). With reference to nutrient return via litter, it was observed that the total litter produced was 4,574 kg ha-1 and the nutrients returned amounted to 46 kg ha-1 N; 3 kg ha-1 P; 39 kg ha-1 K; 86 kg ha-1 Ca and 21 kg ha-1 Mg. Studies on interception of rainfall and nutrient return through rain-wash have shown that among the nutrients return was highest for Ca (1.87 kg ha-1) followed by Mg (1.09 kg ha-1), K (0.98 kg ha-1), N (0.36 kg ha-1) and the least for P (0.11 kg ha-1). Nutrient cycling on an annual basis was worked out for the plantation and it was found that of the total uptake of various nutrients (178kg N ha1 yr1, 248 kg K ha-1 yr-1, 387 kg Ca ha-1 yr-1 and 109 kg Mg ha-1 yr-1, 74 to 91% was retained in the non-photosynthetic biomass and the rest returned to soil. These results were compared with nutrient cycling in 20-year-old teak plantation and found that at younger age teak retains more nutrients in its biomass. As the plantation gets older, it retains less and returns more quantity of nutrients. These results suggest that as the age of plantation increases, teak becomes an eco-friendly species by not adversely affecting the ecology of the site.Keywords

Studies on different pathways of nutrient return through litterfall and rain-wash were carried out in a young teak (Tectona grandis L. f.) plantation at five years age (Density 2500 trees/ha). The total litter produced was 4574 kg/ha and the nutrients returned amounted to : nitrogen - 46kg/ha; phosphorus- 3 kg/ha; potassium 39kg/ha; calcium 86kg/ha; and magnesium 21kg/ha. Studies on interception of rainfall have shown that, the total incident rainfall recorded for this study during the year 2000 was 1013 mm. Of which, 28.97% was intercepted by the canopy, while 7.66% was accounted for stemflow and 63.37% for through fall. With regards to nutrients return through rain-wash, it was found that, throughfall returned more quantities of all nutrients, than stemflow. Of the total return (litter + rain wash) of various nutrients, maximum amount (kg/ha) of return was accounted for calcium (87.40) followed by nitrogen (46.56), potassium (40.31), magnesium (22.13), and the least for phosphorus (3.31). Among these two pathways of nutrients return, litterfall contributed greater amount of all nutrients (from 95 to 99%), when compared to rain wash (0.8 to 4.9%). These results were compared and discussed with nutrients return and nutrient cycling in 20 years old teak plantation and suggest intensive silvicuItural practices in teak plantations during the initial stages of growth to enhance the productivity.- Precambrian Carbonatites of Tamil Nadu, South India

The newly discovered carbonatites of Tamil Nadu are Upper Precambrian in age. They are associated with alkali syenite massifs in Tirupattur area, where the fault system directed NE-SW, very likely represents an ancient deeply eroded trough or rift valley. The carbonatites are mostly beforsitic (para-ankeritic); and pyrochlore mineralization found here is unique in the world, as in general pyrochlore is not reported from beforsitic carbonatites. Both geological setting and petrological features support the view that the Tamil Nadu carbonatite province differs in many respects from Narmada Valley province in India as well as from other carbonatite provinces all the world over.- Rare Earth Minerals of Carbonatites of Tamil Nadu

Measurements of lead isotope ratios on some Indian galenas and calculation of single-stage model ages were presented in a previous paper. Techniques have been improved since then, and more samples from some of these areas and several new samples have been measured. The present measurements cover a wide age-span, Eocene to Archaean (∼3300 m.y.) and the Pb-isotope abundances are not inconsistent with a 2-stage evolution of lead which show an episodic change in μ-value at ∼ 3000m.y. Model ages and μ-values have been calculated using single and double-stage models and an attempt made to interpret these values.- Ganga-Pollution and Health Hazard

The lithology of the Ganga basin especially the carbonates of the recent alluvium, controls the river water chemistry. Illites and kaolinite are the dominant clay minerals in the suspended sediments. The average TOS is 171 ppm and essentially reflects the Indian river-water average.
Considering the sediment transport at Farakka (744 million tonnes/yr) as a measure, the Ganga is placed as the third largest sediment transporting river of the world after the Yellow and Amazon rivers. Basin area and discharge, rather than the basin elevation, control the erosion rate. The total erosion rate (549 t/km2/yr) of the basin at Calcutta is almost three times that of Amazon and three and half times that of the world average (150 t/km2/yr).
The high sedimentation fate (42 mm/yr) in the Yamuna around Delhi is mainly due to the solid waste supply from urban areas. For selective heavy metals, the total drain anthropogenic contribution to the river Yamuna is Mn (42%), Fe (76%), Cu (62%), Zn (90%) and Pb (50%) of the metal increase in the sediments from Wazirabad to Okhla. Excellent correlation among Cu, Zn and Pb in the core and in surface sediments indicates their common source. The additional metals carried into the surface and core sediments of the Yamuna due to increased human utilization of the river basin are in relatively mobile fractions of the sediments and hence pose clear environmental hazards.

An attempt is made to evaluate the environmental geology of non-Himalayan rivers of India. These twenty river basins including eleven medium basins together drain nearly 25 per cent of the sub-continent. The annual transport of suspended sediments and dissolved salts by these rivers have been estimated to be around 370 million tonnes and 61 million tonnes respectively. The rate of physical erosion among these basins range from 799 tonnes/km2/yr to 16 tonnes/km2/yr. Similarly, chemical erosion ranged from 110 tonnes/km2/yr to 22 tonnes/km2/yr.
Among the rivers considered, the chemical composition of water indicates that Cauvery carries a large silica load (39 ppm), while the TDS is low (172 ppm), whereas Sabarmati has the highest TDS (352 ppm). Krishna waters show the highest alkalinity. In all the rivers, conductivity shows good correlation with TDS. Sediment chemistry indicates that Cauvery river sediments are most siliceous while that of Godavari are least siliceous. In both these cases, average SiO2 is higher than the Indian average river sediment. Similarly, Fe in southern river sediments is very high while P is very low compared to the Indian or world average. Apparently local geology (Shield area hard rocks in southern India and Deccan Traps in central India) control the water and sediment characteristics of the peninsular rivers.

Water quality studies in the mining areas clearly point out to the contributions made by the mining activity to the chemical composition of Bandal flver in the Durmala and Maldeota region Levels of phosphates and fluofide in the water are enhanced even in canal waters in the Debra Dun region Drinking water in some taps in Doon valley also show higher levels of contammation for F and P The Bandal fiver carnes total dissolved solids of about 550 ppm which is much higher than the average Indian and world river waters Throughout the region all surface waters are supersaturated With respect to fluorapatite, hydroxyapatite and carbonate apatite. In reality, this equilibrium assembly is not reflected in the phosphate minerals present In tbe river sediments Phosphate minerals constitute nearly half the population of the alluvial sediments in the region with pockets of pyrite minerals up to 10% of the sediments by weight Trace elements like Cu, Cr and F show good Correlation with the P content in the sediment suggesting common sites within the sedlment grains.- Transport and Fractionation of Pb in River Sediments from the Indian Sub-Continent

The distribution of Ph and As in the bed sediments as particulates from the Ganges. Brahmaputra, Godavari, Krishna and Cauvery rivers has been studied. While the Pb levels in bed sediments vary from a low of 2 μg Pb/gm in the Ganges to a high of 32 μg Pb/gm in Godavari, the corresponding particulate Pb load varies by a factor of 5-40 times the bed load from a low value of 5 μg Pb/gm particulates of Krishna to a high value of 1075 μg Pb/gm in the same river. Downstream variations in all rivers are generally erratic both for particulate and bed Pb-Ievels. All the river sediments indicate a very good correlation between Pb and As on the one hand and heavy metals such as Fe, Zn, Cu etc. on the other.The Himalayan river sediments generally exhibit strong grain-size control on the fractionation of Pb and As, whereas the peninsular rivers do not show a systematic partitioning of Pb and As in various size populations.

The Proterozoic carbonatites and associated pyroxenites and syenites of Tamil Nadu are emplaced in the Precambrian gneissic rocks. The carbonatite complexes are located along a major NE trending lineament. In Sevathur, dolomitic carbonatite is predominant over sovite and ankeritic carbonatite whereas in Samalpatti, sovite and silico-sovite form the major bulk of carbonatite mass with small dykes of dolomitic and ankeritic carbonatites. In different types of carbonatites, in addition to calcite, dolomite and ankerite, phlogopite, amphibole, magnetite, and apatite are found in varying amounts between 2% and 10% with accessory amounts of pyrochlore, perovskite, monazite, NbiImenorutile, zircon, baddeIeyite, pyrite, ilmenite, galena and thorite. Both mica and amphibole show change in composition from Fe-rich in syenite and sovite to Mg-rich in the dolomitic carbonatite. The carbonatites are enriched in Ba, Sr, Nb, REE's, Th and U in comparison to the primitive mantle values. Pyroxenites are characterized by high abundances of Mg, Cr and Ni and, low abundances of Nb and Zr. The petrographic evidence, with globules silicate rocks surrounded by carbonatitic matrix is sufficiently clear to suggest a genetic link between syenite and carbonatite by liquid immiscibility.Keywords

This paper presents the results of field studies, and palaeostress analyses of the mesoscale fractures and veins in Cauvery basin. It shows that different sedimentary sequences (119-64 Ma) are cut by tensile structures that belong to two successive phases of post-Palaeocene brittle tectonics (I) an early phase during which bedding parallel fractures and veins were developed due to horizontally directed maximum compression and vertical extension, and (II) a late phase of hydraulic fracturing in a tectonic regime of vertically directed maximum compression. Dynamic analyses imply triaxial and axial compression deviatoric states of palaeostress during first and second phases of fracturing, respectively. Very high pore-fluid pressure and low differential stress, during the second phase of fracturing, resulted into hydraulic brecciation as a consequence of simultaneous extension in different orientations. We suggest that the development of the mesoscale extensional (mode I) fractures in Cauvery basin is due to reactivation of large-Scale normal faults in the basement rocks.Keywords

The Santonian Campanian sequence of the Cauvery basin was documented with lesser detail owing to its lesser fossiliferous nature and relatively highly fossiliferous bounding stiata. Micro mesoscale lithofacies analysis coupled with documentation of sedimentary and tectonic structures, supplemented by bio and ichnofacies data of the sequence revealed that this sedimentary record represents the development of Gilbert type delta. Various stages of delta development were interpreted to have resulted during a third order glacro eustatic sea level cycle. It is surmised that faulting at the dawn of Santonian that brought down topographic and structural highlands into lows permitted marine transgression and creation of steeply sloping river valley, augmenting intense continental erosion and influx of detrital sediment into the basin. In due course of time, smoothening of valley slope, submergence of river mouth by rising sea level coupled with cessation of detrital influx led to the demise of the deltaic deposition. The information that the bounding surfaces of this Santonian Campanian sequences are recognised to be of sea level lowstands, that led to generation of good reservoir quality in the ensuing depositional products, when coupled with the occurrences of gas and oil pools in the sequence in offshore area of this basin necessitates intense exploration activities. This study has also indicated the presence of three types of variability of reservoir characteristics as defined by three systems tracts.Keywords

Image processing schemes which exhibits flexibility, adaptability and non-linearity are extremely useful for applications such as image transformation, correction of blurring effects, noise removal, histogram equalization etc. Images with random variations in Signal-to-Noise Ratio (SNR) can be treated with conventional adaptive filters. The demerits associated with adaptive filters are inability to cope with structural variations, limited performance to address low range noise spatial density (typically less than 0.2). This paper addresses these disadvantages and proposes a wavelet transform based filtering scheme for image processing. This scheme uses Peak Signal-to-Noise Ratio (PSNR) as performance metric and the results shows a higher PSNR was yielded by the scheme.

Based on extensive observations, the sediment and the chemical load- both quantity and quality - have been computed for the Indian sub continent. Indian rivers carry total dissolved solids of 159 ppm, which is about 25% more than the world average river water. Indian rivers are also relatively enriched in Na and Cl. They also carry a sediment load of about 1.4 billion tonnes/yr representing 10% of the global sediment flux. The northern rivers carry dominantly illite-kaolinite-chlorite in suspension while the southern rivers carry high exchange capacity clays. The sediment chemistry is comparable to world surface rocks, with corrections for the mobile elements. Heavy metals occur predominantly in the chemically extractable sinks within the river sediments. Limited studies on base metal mining areas in Khetri and Zawar indicated contamination of soil, plants and water in that area.- Hydrochemical Characteristics of Groundwater in Noyyil River Basin, Tamil Nadu, India

Groundwater is the major source for domestic, agricultural and other related activities. An attempt has been made to study the hydrogeochemistry characterization of Noyyil river basin. The seasonal variation of the chemical budget of ions was determined from the hydrogeochemical investigation of the groundwater. Though, the effect of monsoon does not change the order of abundance of cations, it does change the concentration of various ions, and it is found that there was a considerable change in case of all major ions. Broadly speaking, the groundwater has a chemical composition within the permissible limits suggested for drinking water. Nitrates is higher than the acceptable limits in some samples, that is mainly due to the usage of fertilizers. Hydrogeochemistry of groundwater of Noyyil river basin, which is predominantly a hard rock terrain, has been studied to evaluate the quality of groundwater for domestic and agricultural purposes. Groundwater samples from sixty locations were collected both during January 2007 and January 2008 in and around Noyyil river basin and analysed for their major cations and anions. Physical and chemical parameters of groundwater such as EC, TDS and ionic concentrations of Na+, K+, Ca2+, Mg2+, Cl-, HCO3-, CO32-, SO42-, NO-3 and F- have been determined. Based on the analytical data hydrohemical indices like Na%, SAR, RSC and PI have been calculated. The ionic concentration of TDS, Na, K, SO42-, NO-3 and EC in the sampled locations vary spatially and temporally and the same is attributed for severe contaminations. Salinity, SAR, Na% indicate that the majority of the samples are not suitable for domestic and irrigational purposes and far from drinking water standards as prescribed by WHO.Keywords

A field experiment was conducted in theri soils of Tamil Nadu to study the effect of various organics and inorganic fertilizers on the yield and quality of groundnut. Six different organics viz., raw coir pith (RCP), composted coir pith (CCP), goat manure (GM), farm yard manure (FYM), poultry manure (PM) and bio-digested press mud (BDP) were utilized using groundnut var VRI 2 as a test crop. The result indicated that application of recommended NPK+BDP @ 7.5 t ha-1 produced the maximum pod yield. The highest oil yield was recorded in the treatment receiving recommended NPK+PM @ 5 t ha-1. The BDP application in combination with recommended NPK significantly improved the quality of groundnut oil compared to other organics applied. The significant increase in soil available nitrogen, phosphorous and potassium was observed in all treatments that received organics and inorganic fertilizers. There was no significant improvement in organic carbon as well as physical properties of the soil whereas physico-chemical properties such as soil reaction and electrical conductivity were significantly influenced by various INM treatments.Keywords
