Abstract. Radioactive basic metavolcanics i.e. amphibolites
of Bodal-Bhandaritola areas have been assigned Lower Proterozoic age of Nandgaon Group.
Meso to epizonal reconstitution of acidic
metavolcaoics as myolitic suites during polyphase tectonism with
accompanying metamorphism, shearing and hydrothermal activity
has resulted in the formation of ore grade amphiboite bodies. Uranium mineralisation is essentially restricted to shears
trending N 18° E·S
18°W and N 40°
W·S 400 E in Bhandaritola and Bodal respectively
In the east to quartz porphyry in west.
Peribatholithic contact of Dongargarh granite
with the uraniterous amphibolite and quartz porphyry
shows distinct effects of protoclasis aiding
in enrichment of uranium (upto 8400 ppm)
within host rocks.
Notably an increase in uranium content shows an
increase in Si. A1, total alkalies and Pb, but Mg. Ca. Fe, Mn, P20s show a concomitant
decrease. While the trace elements (Ba.Rb, Sr, Ni.
Zn and Cu) show an inconsistent and ersuc behaviour. It has
been suggested that amphinbolites with higher Si, Al, total alkalies and Pb
will be uraniferous, even though surface manifestation of uranium is
poor or even lacking.
