摘要
会泽高家阱铅锌勘查区地处滇东北富锗银铅锌多金属矿集区中南部,位于会泽矿山厂大型铅锌矿床北东侧,是近年来在矿山厂铅锌矿床外围新设的勘查区。基于分形几何学方法,对高家阱铅锌勘查区断裂构造体系开展分形研究,并结合地质信息,探讨其地质意义。研究表明:研究区整体断裂构造、NE向断裂构造、近NS向断裂构造及NW向断裂构造容量维分别为1.2681、1.1491、0.8504、0.9056,信息维分别为1.3892、1.2199、0.9368、0.9802;研究区整体具有一定的成矿潜力,而单一类型断裂构造的连通性均不足以促使成矿流体的有效运移;研究区综合有利成矿区域可划分为两部分,分别呈NE向、NW向展布。
The Gaojiajing lead-zinc exploration area in Huize is located in the central and southern part of the germanium-rich silver-lead-zinc polymetallic ore concentration area in northeastern Yunnan.It is located to the northeast of the large-scale lead-zinc deposit in Huize Mine Factory and is a newly established exploration area in the periphery of the lead-zinc deposit in recent years.Using fractal geometry,this paper conducts fractal research on the fault structure system of the Gaojiajing lead-zinc exploration area and discusses its geological significance in combination with geological information.The results show that the capacity dimensions of the entire fault structure system,NE-trending faults,near-NS-trending faults,and NW-trending faults in the study area are 1.2681,1.1491,0.8504,and 0.9056,respectively,while the information dimensions are 1.3892,1.2199,0.9368,and 0.9802,respectively.The entire study area has certain metallogenic potential.However,the connectivity of a single type of fault structure is insufficient to promote the effective migration of ore-forming fluids.The comprehensive favorable metallogenic areas in the study area can be divided into two parts,distributed in NE and NW directions,respectively.
