寒武系底部硅质岩向粘土岩过渡地带 ，或两者的互层以及蚀变粘土岩是多种元素富集成矿的有利岩层。

Transitional tervain from siliceous rock to clayrock, both interbed and altered clayrock are favourable strata of all kinds of elements concentrated mineralization underneath the Cambrian.

该“潜伏”脉带的金矿化限于寒武系以硅质岩为顶板的碳质页岩中，明显受成矿前产生的韧性剪切带控制。

Gold mineralization of the zone is confined only to the Cambrian carbonaceous shale overlain by siliceous rocks, and apparently controlled by a premineral tough shear zone.
