| 摘 要： | 老湾金矿是我国近年来探明的重要的大型构造蚀变岩型金矿床.金矿体(或矿脉群)、控矿构造、岩浆岩、赋矿地层、近矿热液蚀变带以及周围地质体之间存在某种物性差异,因而有明显的地球物理异常特征,构成了金矿床重要的地球物理找矿标志.作者试图在矿床地球物理特征研究的基础上,总结地球物理找矿标志,确定找矿勘查物探方法组合流程,以期配合、指导正在进行中的桐柏-大别山北坡金银成矿带的普查找矿工作.

| Abstract: | the Laowan gold deposit is an important large-size tectonic altered rock type gold deposit discovered in recent years. There exist certain differences between gold orebodies (or ore vein groups), ore-controlling structures, magmatic rocks, ore-hosting strata, near-ore hydrothermal altered zones and surrounding geological bodies, which result in obvious geophysical anomalies that constitute important geophysical prospecting indicators for gold deposits. Based on the study of geophysical characteristics of the ore deposit, the authors have tentatively summed up geophysical prospecting indicators and determined the association and flow chart of geophysical prospecting techniques so as to serve and guide the current reconnaissance and prospecting work in the gold-silver ore-forming belt on the northern slope of the Tongbai-Dabie Mountains.acte |
