Brannerite occurs as subrounded to subangular grains (0.05mm to 20mm) in marble, quartzite, carbonate rock, quartz biotite schist and albitite, and in soils derived from these lithounits of Ajabgarh Group of metasediments around Kachera dam-Ladikabas area of Sikar district, Rajasthan. It alters to rutile along the margins and fractures. The analysis shows 30.6-36.9% UO3, 0.9 to 3.2% UO2, 33.40% TiO2 and 3.4% total (REE)2O3.

Abstract


Brannerite occurs as subrounded to subangular grains (0.05mm to 20mm) in marble, quartzite, carbonate rock, quartz biotite schist and albitite, and in soils derived from these lithounits of Ajabgarh Group of metasediments around Kachera dam-Ladikabas area of Sikar district, Rajasthan. It alters to rutile along the margins and fractures. The analysis shows 30.6-36.9% UO3, 0.9 to 3.2% UO2, 33.40% TiO2 and 3.4% total (REE)2O3.
