根多铀矿点是中核地质在西藏铀矿调查中发现的前景良好的一处矿点。含矿层是以退积型潮坪相、滨岸相、滨外陆棚交替沉积的上三叠统甲丕拉组(T3j)。整个含矿层呈北西向展布,长4000m,宽(厚)0.4～13m不等,平均厚度3m。矿化呈似层状、透镜状,矿层(体)与围岩逐渐过渡。矿石中铀含量0.003%～0.855%,一般0.02%～0.30%,其成矿作用认为是热液成因,其类型可能属花岗岩外接触带型。
Genduo mineralized area is discovered lately by our institute in Tibet.The ore bed is Jiapila group in upper Triassic that sediment alternately by recede sedimentary tidal-flat facies,seashore facies and seashore outside shelf facies.The whole ore bed spreaded northwest,4000m length,0.4~13m large(thick),average 3m thick.The mineralization spreaded as floor and lens body,the ore bed(body) transition with wall rock gradully.There is 0.003%~0.855% uranium in the ore,average 0.02%~0.30%.We elementary think the mineralization are sediment cause and hydrothermal cause.The type maybe is granite outside touch belt type or sediment alteration type.
