孟宪民将赋存于东川元古代昆阳群落雪白云岩中的层状铜矿命名为“东川式铜矿”。该类矿床广泛分布于康滇地轴昆阳群(会理群)落雪组地层中(图1),并严格受一定的岩性地层组合控制,基本上是沉积变质的或火山沉积变质的成层矿床。简而言之,就是一定层位的矿床。据此,笔者将这类矿床更名为“东川式层控铜矿”。此类矿床在成岩阶段就已基本形成,尔后经受各种地质作用(区域变质、地壳运动、次火山一岩浆
Meng Xianmin stratiform copper deposit hosted in Snow dolomite of the Proterozoic Kunyang Group in Dongchuan is named “Dongchuan Copper Mine.” These deposits are widely distributed in the Loxue Formation of the Kunyang Group (Huili Group) of the Kangdiian axis (Figure 1) and are strictly controlled by a combination of lithologic strata that are essentially stratigraphic or volcanic sedimentary metamorphic strata Deposits. In short, it is a certain level of deposit. Accordingly, I will be renamed this type of deposit “Dongchuan layer control copper.” Such deposits have been basically formed in the diagenetic stage, and then undergo various geological effects (regional metamorphism, crustal movement, sub-volcano-magma
