本文以几个典型金矿床为例,对鄂东南地区金矿床地球化学特征和地球化学异常进行了探讨,取得了该区金矿异常的参数特征资料。总结了区域金矿床成矿地质背景的地球化学条件,并为该区金矿物质来自岩浆或地壳深部的认识提供了充分依据。建立了区域金异常地球化学评价标志;原生异常含矿性评价标志;判断矿化类型和矿体剥蚀程度的标志。利用这些标志,确定了找金重点地段。
In this paper, taking several typical gold deposits as an example, the geochemical characteristics and geochemical anomalies of the gold deposits in southeastern Hubei Province are discussed, and the parameter characteristics of the gold deposits in the area are obtained. It summarizes the geochemical conditions of the regional gold deposits metallogenic geological background and provides a sufficient basis for the understanding of the gold minerals in the area from the magma or deep crust. Established regional gold anomaly geochemical evaluation marks; primary abnormal ore-bearing evaluation marks; and signs of mineralization type and ore body denudation degree. Use of these signs, to find the key areas to find gold.
