扬子-江南区的下寒武统地层中,广泛发育着以镍、钼为主的多元素沉积矿层.这种矿层分布广,层位稳定,有用组分多,常与磷矿或石煤伴生.矿石难选,但最近的选矿试验证明可以达到工业要求. 诸暨铝矿是一个由早寒武世的沉积钼矿,经后期改造而成的层控型矿床.它包括同生沉积钼矿、沉积改造型层状铝矿、夕卡岩型铝矿和岩浆热液石英型钼矿等一系列矿床(图1).研究该区多种类型铝矿的生成条件及其内在联系,不仅具有理论意义,而且对指导找矿也有一定实际意义.本文着重讨论本区各类钼矿的成矿机理及其找矿意义.
In the Lower-Cambrian strata of the Yangtze-Jiangnan area, a multi-element sedimentary deposit dominated by nickel and molybdenum is widely developed, which is characterized by a wide distribution, stable bedding and many useful components and is often associated with phosphate rock or stone coal Ore is difficult to pick, but recent ore dressing tests have shown that industrial requirements can be met.Zhuji Aluminum is a stratiformically controlled deposit that was formed from a later Cambrian deposit of early Cambrian sedimentary molybdenum, and consists of syngenetic sedimentary molybdenum, Sedimentary alteration stratiform aluminum, skarn-type aluminum and magmatic hydrothermal quartz molybdenum and a series of deposits (Figure 1) to study the formation of many types of aluminum ore in the area and its internal relations, not only has the theory Significance, but also has certain practical significance to the direction of ore prospecting.This paper focuses on the various types of molybdenum mineralization in this area and its ore prospecting significance.
