Abstract

Quartz-pebble-conglomerate(QPC) bearing unconformable zone at the base of Bababudan Group of rocks inDharwar Craton in southern India is well known for its stratigraphicsignificance and uraniferous nature. Over this QPC zone, soil cover is verythin which is almost devoid of vegetation. A cursory biogeochemical study hereindicated poor (170 to 520 ppb) uranium content in the scantily occurring herbsand shrub species as well as in the soil substratum (1.8 - 3.1 ppm). The valuesin plant species are much below the background values. Almost barren nature ofsoil surface and stunted growth of herb and shrub species suggested thatgeobotanical rather than biogeochemical study is more serviceable as a clue forthe hidden QPC-type horizons, which quite often bear signatures of uraniummineralization.
