四川木里梭罗沟金矿床位于甘孜—理塘构造成矿带的南段、唐央复式背斜南东倾伏端(或唐央穹窿南缘),目前已探明储量属大型岩金矿床。矿体产于上三叠统曲嘎寺组蚀变基性火山岩中,受近东西向断裂控制。矿床具多期成矿特点,属构造蚀变岩型—中低温热液型金矿床。
四川木裏梭囉溝金礦床位于甘孜—理塘構造成礦帶的南段、唐央複式揹斜南東傾伏耑(或唐央穹窿南緣),目前已探明儲量屬大型巖金礦床。礦體產于上三疊統麯嘎寺組蝕變基性火山巖中,受近東西嚮斷裂控製。礦床具多期成礦特點,屬構造蝕變巖型—中低溫熱液型金礦床。

The Suoluogou Au deposit in Muli, Sichuan lies on the southern margin of the Tangyang dome in the southern section of the Garzê-Litang tectonic-metallogenic belt. The deposit is confined to the altered basic volcanic rock of the Upper Triassic Qugasi Formation and controlled by nearly EW-trending fracture zone. The deposit is a structural altered rock type one which was formed by multiple ore-formation.
