In the sedimentary terrain of Tillegra, N.S.W., domain-2 having an average dip of 56° has produced 79 cm thick soil profiles but domain-3 having an average dip of only 9° has produced only 46cm thick profiles. Relative occurrences of B and C horizons also stand much higher in domain-2 than in domains 1 and 3. It is clear from this that areas having higher dip value produce thicker and mature profiles, whereas low dipping areas produce thinner and immature profiles.Full Text

The Patcham-Chari Formations of Jhurio Hill, Kachchh, have yielded a rich and diverse microfossil assemblage dominated by foraminifers. 95 foraminiferal species are being reported from this section assignable to 47 genera belonging to eighteen super families. The present foraminiferal assemblage suggests a Bathonian-Oxfordian age for the Palcham-Chari Formations of Jhurio Hill and also helps to demarcate the Bathonian/Callovian as well as Callovian/Oxfordian boundaries in this area.Keywords

In the present work, we bring out the palaeoenvironmental significance of the growth-form morphology of coralline algae present in the Ninniyur Formation (Palaeocene) of the Cauvery Basin, South India. Our observations indicate presence of four types of coralline algal growth forms in the studied sections of the Ninniyur Formation: laminar, branching, columnar and massive and fragmented. They seem to have been controlled by depositional environments, each characterising a distinctive set of conditions pertaining to water-energy and depth. It appears that the carbonate environment, in which the Ninniyur Formation was deposited, was well differentiated into subenvironments due to changing environmental constraints (depth of deposition and hydraulic energy). The biota responded to these factors through habitat partitioning which possibly hastened the process of evolution of varied types of coralline algal associations and growth morphology leading to distinctive biofacies characters.Keywords

A small deposit of lead and zinc was established in southern part of Sawar metasedimentary belt during third phase of drilling. The Mise-A-La-Masse survey, a post discovery geophysical method carried out in the boreholes of this belt has yielded significant results. This method has been useful in delineating the subsurface disposition of mineralised zones and their lateral extension. This technique is also successful in the area in establishing correlation between different parts of an ore body with varying sulphide percentage, which are located distantly but are in electrical continuity. Hence the Mise-La-Masse method has been of immense help in planning the boreholes thereby optimizing drilling cost in the Sawar Belt. The composite map of equipotential line and chargeability contour has indicated that the contour pattern and disposition of anomaly axes are similar in both the cases.Keywords

Integrated geophysical surveys comprising resistivity and chargeability (both gradient and Dipole-Dipole), SP, magnetic and borehole Mise-a-La-Masse methods coupled with geoelectrolysis techniques and geochemical analysis of soil samples led to the delineation of several auriferous sulphide bodies in the eastern Mahakoshal belt. Combined analysts of surface geophysical, borehole geophysical and geoelectrolysis methods are presented in respect of three areas viz. Gurahar Pahar, Tisihwa and Gulaldih Geophysical interpretations were based on the observed response (parametric survey) over the different exposed rock types in the area Moderately high chargeability coupled with moderate low resistivity, negative SP, high Geo-Electrochemical anomaly supported by geochemical soil sample anomaly proved to be indicative of concealed sulphide conductors. Mise-a-La-Masse technique delineated the extension of the sulphide body projected on a horizontal plane and its dip direction.Keywords

The Satpura basin, located in central India, is the westernmost exposed Gondwana basin. This basin is situated south of the Narmada-Son Geofracture (NSG) and north of the Betul-Chhindwara plateau. The basin is spindle-shaped with a length to breadth ratio of 4:1. The shape of the basin is governed by the intersection of three prominent tectonic grains. These are (1) ENE-WSW strain parallel to the NSG strain in the north, (2) NW-SE trend conforming to thc Dharwar tectonic strain in the southwest and (3) NE-SW trend parallel to the Eastern Ghat tectonic strain.
The basin is subdivided into the Pench-Kanhan sub-basin in the south and Denwa sub-basin in the north. These sub-basins are separated by the Malni-Tamiya high which runs subparallel to the strike of the basin. The basin is occupied by outcropping Gondwana sediments of Permian, Triassic and Cretaceous age. These sediments are subdivided into the lower unit comprising Talchir, Barakar, Motur and Bijori Formations, the middle unit of Pachmarhi and Matkuli Formations and the upper unit of Jabalpur Formation and Infra-trappean sediments.
The evolution of the Satpura basin could be considered in terms of pre-rift, syn-rift and post-rift phases. The pre-rift phase is characterised by the development of sag in which sediments of the Talchir Formation were uniformly deposited. Sediments deposited in prograding fluvial and paludal environments, representing the Barakar Formation followed this. Tectonic readjustments related to initial break up of the Gondwanaland resulted in the development of a rift system in which remaining sediments of the Barakar Formation and entire Motur and Bijori Formations were deposited in a "Venetian blind" pattern due to progressive subsidence, rapid sedimentation and northward shift of depocentres caused by a northward migration of the rift. Thesc pre-rift and syn-rift phases were initiated in the Early Permian and culminated in Latest Permian. The post-rift phase, which was initiated in the Late Lower Triassic, witnessed the deposition of sediments of Pachmarhi and Matkuli Formations. Subsequent to the Jurassic hiatus, sediments of Jabalpur Formation were deposited overlapping thc older sediments. Deposition of Infra-trappean sediments was the last episode of the post-rift phase. These are essentially calcretes formed on the peneplained surfaces of the older Gondwana sediments.

The present paper records eight Rhodophycean taxa from the Kallakudi limestone of the Uttatur Group (Lower Cretaceous) exposed in the quarries at Kallakudi and Olaipadi near Govindarajapatnam of the Cauvery Basin, south India. Of these, four species (Melobesioideae gen. et sp. indet 1, Melobesioideae gen. et sp. indet 2, Lithophyllum alternicellum and Pseudoamphiroa propria) belong to corallinaceae family, one species (Polystrata alba) is assigned to Peyssonneliaceae family, two species (Solenopora urgoniana and Parachaetetes asvapatii) are placed under Solenoporaceae; and one species (Sporolithon sp.) is referable to Sporolithaceae family. Among these, three taxa (Solenopora urgoniana, Lithophyllum alternicellum and Pseudoamphiroa propria) are recorded for the first time from India. The study also includes observations on ultrastructural morphological features of Parachaetetes asvapatii. The observations reveal absence of cell fusions, which confirms its affinities with Solenoporaceae. Palaeoecological data indicate that the assemblage from the sequence at the Kallakudi quarry is characteristic of lagoonal to reefal environment, whereas the Olaipadi quarry sequence near Govindarajapatnam points to 20 m to 30 m deep environment characterized by high - to moderate energy conditions.Keywords

The Fulra limestone (middle Eocene) exposed in the areas around Jhadwa and Harudi villages, southwestern, Kachchh reveals presence of a rich assemblage of calcareous algae belonging to the Chlorophyceae and Rhodophyceae along with abundant foraminifera. In the present paper, eight species belonging to eight genera of calcareous algae are described. These include Dissocladella longijangensis, Sporolithon keenani, Corallina crossmanni, Arthrocardia sp. Misra et al. 2001, Lithothamnion ishigakiensis, Melobesioideae gen. et spec. indet. 1, Melobesioideae gen. et spec. indet. 2 and Lithoporella melobesioides. Out of these, one taxon belongs to the family Dasycladaceae. Among the remaining taxa, one taxon to the family Sporolithaceae, three taxa to the family Corallinaceae and three to the family Hapalidiaceae. Two coralline species, Corallina crossmanni and Lithothamnion ishigakiensis, are recorded for the first time from India. Another species (Dissocladella longijangensis), though known from other areas of India, is new to the study area.
The dominant group of the calcareous algal association in the study area is represented by non-geniculate coralline algae comprising Hapalidiaceae, Corallinaceae and Sporolithaceae; the minor component is represented by dasyclads (chlorophyceae). These algal groups, together with their growth-forms (arbosescent, encrusting to fruticose, warty), and the associated foraminifera indicate that the depositional environment of the Fulra limestone ranged from deeper innerto mid-ramp environment (40-80 m) in the upper photic zone.

The present paper records nine species of coralline algae from the Prang Formation of middle-late Eocene age from the Jaintia Hills, Meghalaya. The algae are associated with the larger foraminifera including Nummulites, Alveolina and Discocyclina throughout the succession. The temporal distribution of algal species indicates that seven species are known from the Eocene. Of the remaining two, one ranges from the Palaeocene to Eocene and the other is Palaeocene in age. The coralline algae and larger foraminifers are differentiated into two associations, the lower one indicating inner-ramp environment of high energy and the upper one showing deposition in relatively calm waters of deeper ramp environment.Keywords

The Quaternary sediments of the Aramda Reef Member of the Chaya Formation exposed in the Mojap coast near Mithapur, Gujarat are characterized by well-developed coralline algal build-ups. These algal build-ups are exceptionally rich in coralline algae and corals. In the present paper, thirteen species belonging to eight genera of coralline algae are described. Out of these, seven species (Titanoderma nataliae, Lithophyllum nitorum, Lithophyllum quadratum, Spongites sp. Brandano et al., 2005, Sporolithon lvovicum, Mesophyllum fructiferum and Lithothamnion praefruticulosum) are the new records for India. Four species (Titanoderma pustulatum, Sporolithon intermedium, Mesophyllum commune and Phymatolithon sp.) are first time recorded from the study area. Among the major framework builders of coralline algae of the Aramda Reef Member are Lithophyllum, Titanoderma, Sporolithon, Mesophyllum and Lithothamnion.
Two associations of the coralline algal assemblages can be distinguished: one indicating shallow water, high-energy conditions is developed in the upper part, while the other suggesting deposition in low-energy conditions is characteristic of the lower part of the succession. These algal associations, together with their growth-forms (encrusting, warty to fruticose, layered) come from stratigraphically separate beds. They indicate that the temperature, depth and hydrodynamic energy conditions also fluctuated during deposition of the Aramda Reef Member. It is concluded that the lower Hapalidiaceae-Sporolithaceae association dominated during warmer interval, whereas the upper lithophylloids association flourished in relatively low-temperature conditions. The associated corals indicate that minimum winter sea surface temperature remained above 18°-20° C.
