A partly concealed radioactive alibitized pegmatoid/quartz albitite body (1200 m x 0.5 to 20 m) containing 0.010 to 0.190% U3O8 and 0.007 to 0.076% ThO2 and about 20 brick red coloured albitite lenses varying in dimension from 13 m x 7 m to 220 m x 12-30 m and containing 0.022 to 3.50% U3O8 and 2 are described at Banjaron Ki Dhani, new Maonda in north Rajasthan. Davidite, brannerite, rutile, anatase, zircon, monazite and traces of uraninite have been identified in the albitites. A metasomatic origin for the albitites is suggested. The distribution of albitites along NE-SW to NW-SE and E-W trending weak structural planes and the coincidence of 'Albitite Line' with Kaliguman lineament, demonstrates the tectonic control of albitization.Keywords

The paper reports for the first time uranium mineralisation associated with phosphatic tuffaceous shale of the Lower Vindhyan Semri Group, near the southern margin of Son Valley around Mankisar-Karaundiya-Kathar area. Grab samples from this rock unit analyzed upto 900 ppm of U3O8 and upto 18.5 % of P2O5. Uranium enrichment in tuffaceous shale has been inferred due to hydrothermal activity.Keywords

Quaternary sequences of mud/silt with carbonaceous matter and coaly layers, sandstone and conglomerate is found in the structural depressions near Jahajpur basin in Rajasthan. Uranium is also found in these sediments which may have been derived from the basement of Berach Granite and phyllites of Jahajpur Group.- A Note on the Uranium Occurrences and Probable Controls for Mineralisation in Upper Gondwana Sequence of Kharatoria Area, Chhindwara District, Madhya Pradesh
