通过讨论白银火山穹隆的构造—地层模型，指出核部主体由前寒武系（震旦系为主）酸性火山岩—次火山岩组成；外环部分主体由寒武—奥陶系中基性—碱性火山—沉积岩系组成。二者以不整合面为界。晚期火山岩常复合于早期火山岩中，构成一向东倾伏的复合型火山穹隆体。已知矿床均产于核部。在总结白银矿床成矿模式及找矿准则的基础上，新提出位于火山穹隆东部外环部位之米心掌—大洞沟—黑石山沟一带为一有远景的隐伏矿预测区。 By discussing the tectonic-stratigraphic model of the volcanic dome in Baiyin, it is pointed out that the core of the core is composed of Precambrian (mainly Sinian) acidic volcanic-subvolcanic rocks, and the outer part of the main body is composed of Cambrian-Ordovician medium- Sex volcano - sedimentary rock composition. The two are not integrated surface for the community. Late volcanic rocks often compose early volcanic rocks, forming a composite volcano dome that has been plunged eastward. Known deposits are produced in the nuclear. On the basis of summarizing the metallogenic model and ore-prospecting criteria of the Baiyin deposit, a new prospective concealed ore prediction area is newly proposed in the area of ​​the outer core of the volcanic dome in the area of ​​Mizongpai - Dadonggou - Heishishanggou.
