Thmly laminated, pelagic, Banded Iron Formation (BIF) of Lower Proterozoic Aravalli Supergroup lies close to basement granite and phyllites over a stretch of 5 km along the Udaisagar-Kalamagra tract, Udaipur district, Rajasthan. BIF is characterised by rhythmic stratification of meso- and micro-bands of iron oxides with light coloured bands of silica/chert. Banded Haematite Quartzite (BHQ), a part of BIF, is 5-30 m in width and is intercalated with carbonaceous shale/phyllites. Primary sedimentary structures, viz., bedding, banding, laminations, convolute lammations and synsedimentary breccia and faults, coupled with low value for Co/Ni (0.18; n = 7) suggest its deposition as chemogenic sediment in a calm, tranquil and deep-sea environment.BIF analysed on an average (n=5) 35.81 % Fe2O3 and 34.5% Si02 with enrichment in sulphides and uranium (138 ppm). Correlation matrix shows strong positive correlation between uranium and copper (r = 0.80) and negative correlation of U with V, Ni, Co and Mo. Uranium content varies from 100 to 470 ppm (n = 37) and appears to be in adsorbed state on ferric oxide. Field relationship, coupled with ternary plots of Al2O3 - (CaO + MgO) - SiO2, Fe2O3 - (CaO+MgO) - SiO2 and Eu/Sm ratio (av. 0.275; n = 10) confirms its Proterozoic age. BIF exposed at Udaisagar-Kalamagra tract forms a linear belt and resembles the early Proterozoic Lake Superior type in its geochemical signatures.

Groundwater in Palnad sub-basin is alkaline in nature and Na+-Cl--HCO-3 type around Macherla–Karempudi area in Guntur district, Andhra Pradesh. Total dissolved solids (TDS) show strong positive correlation with Cl-, Na+, Ca2+ and Mg2+, and positive correlation with SO2-4, K+ and HCO-3. Calcareous Narji Formation is the dominant aquifer lithology, and water-rock interaction controls the groundwater chemistry of the area. Chloro-alkaline indices (CAI) are positive at Miriyala, Adigopula, Mutukuru, Macherla and Durgi suggesting replacement of Na+ and K+ ions from water by Mg++ and Ca++ ions from country rock through base exchange reactions. Negative CAI values are recorded at Terala, Rayavaram and Nehrunagar, which indicate exchange of Na+ and K+ from the rock as cation-anion exchange reaction (chloro-alkaline disequilibrium).
TDS range from 91 to 7100 ppm (Avg. 835 ppm) and exceed the prescribed limit of drinking water around Mutukuru, Durgi, Rayavaram, Khambampadu and Ammanizamalmadaka areas. Scanty rainfall and insufficient groundwater recharge are the prime factors responsible for high salinity in the area. Fluoride content ranges from <1 to 3.8 ppm and contaminated areas were identified around Macherla (1 sq km; 3.8ppm), Mandadi (1 sq km, 2.1ppm) and Adigopula (2 sq km, <1 to 3.7 ppm). The % Na+ content varies from 17 to 85 with the mean value of 57, and eighty (80) samples showed higher %Na+ in comparison to the prescribed limit of 60 for irrigation water. Sodium Adsorption Ratio (SAR) and % Na+ in relation to total salt concentration indicate that groundwater (51%) mostly falls under doubtful to poor quality for irrigation purpose. Groundwater of Adigopula village is fluoride contaminated and remedial measures are suggested to improve the water quality.

Relationship of hydro-uranium anomalies (2-649 ppb) vis-a-vis underlying uranium ore body has been attempted based on seventy nine water samples collected from the exploratory boreholes on the northern periphery of Srisailam sub basin, Nalgonda district, A.P. Water table is hosted in the granitoid aquifer which underlies the cover rocks of Srisailam Formation. TDS (total dissolved salt) range from 123 to 1088 ppm (x- = 329 ppm) and analyzed >500 ppm in eight samples. Water samples show a strong positive correlation of TDS with Cl- (r=0.90), Na+ (r=0.82), Mg (r=0.80) and a moderate positive correlation with Sr (r=0.48) and Ca (r=0.70). Low value (<0.4) of Normalised Magnesium (NMg) indicates that host rock aquifer has not undergone chloritisation. Accumulate contour plan of uranium ore body shows NW-SE trend and coincides with the hydro-uranium contour. Correlation sections of ore body display true as well as false hydro-uranium anomalies in N-S and E-W profiles. Hydro-uranium anomalies owe their origin to uranium cations, dissolved from the mineralized horizon in to groundwater. Hydro-geochemical orientation survey carried out at Chitrial plateau may be applied regionally in the Srisailam sub basin as an effective tool to explore the concealed unconformity type uranium mineralization below Srisailam Formation.Keywords

There is no record of igneous activity in Upper Proterozoic-Kurnool/Palnad sediments. However, Igneous activity was recorded by number of geoscientists in the Cuddapah Super group of rocks in the Cuddapah Basin. For the first time the authors report the occurrence of eruptive igneous activity in the northern part of Palnad Basin,an equivalent of Kurnool Group, South of Venkataramapuram, Nalgonda district, Telangana State. The Igneous activity has affected the basal unit of Banganapalle Formation. Basal conglomerate is polymitic in nature with clasts/cobbles/boulders of dolerite, granite, granodorite, BMQ, meta-quartzite, quartzite, shale and lime stone of Palnad Formation. The average composition of conglomerate matrix (n=7) is 1.75% Fe2O3, 8.07% FeO, 3.74% MgO%, 8.07% CaO and 38.8% SiO2 which corresponds to basic igneous activity.Keywords

The Ambadongar sub-volcanic carbonatite alkali complex is located about 140 km east of Vadodara, Chhota Udepur district, Gujarat, India and falls in Survey of India Toposheet No. 46 K/1. The complex intrudes Bagh sandstone (Cretaceous) and overlying Deccan basalts (Eocene) and is situated in the Narmada rift zone. The carbonatites came into prominence in the early 1960s with significant discoveries of fluorite and conspicuous radioactivity located near Chhota Udepur, at Ambadongar, the erstwhile Baroda district, Gujarat. Earlier workers have clarified many aspects of the carbonatite complex.Full Text

Recent exploration efforts in Kudada-Turamdih area has brought to light, for the first time, serpentinizedperidotite- hosted uranium mineralization (up to 0.188% U3O8) of polymetallic nature (U–Cr—Ni–Mo–REE–Fe–Mg) in the domain of Singhbhum Shear Zone (SSZ). The peridotite has been emplaced into the Iron Ore Group (IOG) and represents late phase activity in the IOG. Exploratory drilling has established substantial lateral (600 m) and downdip (1000 m) continuity of the mineralization. Subhedral to anhedral disseminated uraninite grains (10–600 μm) with cell dimensions of 5.4498 to 5.4650 Å suggest crystallization in meso to hypo-thermal range (300– 500°C). Magnetite, chromite, molybdenite, cobaltite, nickeline, vaesite, cerussite, pyrite and chalcopyrite have also been identified in the REE enriched (Av. 1457 ppm) uraniferous peridotite. Presence of MgO (18–28%), Cr (295–3165 ppm), Ni (222–9530 ppm), Au (11–30 ppb), Pt (47–95 ppb) and As (15–755 ppm) suggests komatiitic parentage of host rock. Discovery of polymetallic mineralization in serpentinized peridotite, a hitherto unknown geological environment, opens up scope for further research and enhancement of uranium resources in the SSZ.Keywords

In the eastern Dharwar craton, the crescent- shaped Cuddapah Basin forms a large intracratonic basin, comprising Meso–Neoproterozoic sedimentary sequence with volcanic rock components. The sedimentary environment of the Cuddapah Basin, in general, is comparable with peri-tidal complex with shallow marine carbonate shelf and beach environment. Systematic geological studies of the Cuddapah Basin are well documented1,2. The litho-units of the basin are mainly divided into older Cuddapah Supergroup and a younger Kurnool Group. The former is present throughout the basin, while the younger group is seen in its western and northeastern parts. The sediments of the basin overlie the Late Archaean–Lower Proterozoic granitoids intruded by basic and ultrapotassic dykes.Full Text
