Analysis and discussion on the problems existing in the exploration of tectonic hydrothermal gold deposits:An example from the"two mountains"in Anhui
摘要
Abstract
This paper discusses the problems encountered in the exploration and evaluation of tectonically controlled hydrothermal gold deposits in the southern mountains and the Dabie mountains(hereinafter referred to as"two mountains")in Anhui.By analyzing the complexity of endogenetic tectonic mineralization and supergene enrichment mechanism of the gold deposits,this paper reveals the mechanism and principle of tectonically superimposed halo's control on endogenetic mineralization,and on secondary enrichment of the gold deposits in later crustal uplift,denudation,weathering and leaching processes.It is proposed that in deep gold exploration,we should pay attention to screening analysis of the regional geochemical survey information,to characteristic elements and their abnormal changes in the primary halo in borehole rocks in vertical direction,and to other information and means for identification and detection of alteration markers,so as to achieve the purpose of three-dimensional tracing and locating the concealed ore bodies.关键词
