陈国达教授提出的多因复成矿床,具有多成矿阶段,多物质来源,以及多成因类型的“三多”特点。这一新观点对指导鄂东找矿勘探实践有重要意义。本文根据鄂东地质勘探积累的大量资科,探讨了鄂东石炭系层位的多因复成矿床的地质特征,指出了沉积-热卤水改造、火山沉积-岩浆热液改造和沉积-构造改造等三个成因类型。最后,从层、相、位和“多位一体”的成矿模式探索了找矿方向。
The multi-cause complex deposit proposed by Professor Chen Guoda is characterized by multi-mineralization stages, multi-material sources and multi-genesis types. This new point of view is of great importance in guiding exploration and exploration in eastern Hubei Province. Based on a great deal of resources accumulated in the geologic exploration in eastern Hubei Province, this paper discusses the geological features of the multi-factor complex deposits in the Carboniferous strata in eastern Hubei province, and points out the alteration of sedimentary-thermal brine, volcanic sedimentary-magmatic hydrothermal alteration and sedimentary-structural alteration Three types of causes. Finally, we explore the prospecting direction from the strata, facies, bits and the “multiple” metallogenic model.
