位于西域板块宗务隆山-青海南山晚古生代-早古生代裂陷槽泽库弧后前陆盆地的也尔普岗铀矿床产于阿米夏降花岗岩体,含矿围岩为似斑状黑云母二长花岗岩。矿体受断裂构造控制,产状与断裂构造一致。矿体形成的古气候环境炎热干燥。铀矿化的富集由含铀地表水的下渗沉淀和碱交代作用有关。

Located at Zongwulong Mountains of the Western section-Qinghai Nanshan Late Paleozoic-Early Paleozoic aulacogen Zeku-are foreland basin,uranium ore deposits are from the Amixia granite.The ore-bearing wall rock is porphyritic biotite-monzonitic granite.Orebodies are controlled by faults,and the occurrence is accordance with faults.The paleoclimate of ore formation was hot and dry.The enrichment of uranium mineralization reaulted from the infiltration and precipitation of uranium-containing surface water and alkali metasomatism.
