摘要
炎陵—蓝山断裂是湘南地区内的一条活动时间长、规模大的深断裂构造带,对湘南区域矿产的形成和分布起到了非常重要的作用,控制着炎陵-蓝山NE向钨、锡、铅、锌多金属亚成矿带的形成和分布,控制了湘南区内80%之多的大中型有色多金属矿床(田)产出,该断裂既是一条控矿断裂,同时也参入了造矿以及对矿床的后期改造活动。在分析研究该断裂构造带的地球物理背景、地球化学特征、沉积岩相建造、构造岩浆作用等地质特征及成矿作用特点的基础上,作者提出了湘南地区横向上两大找矿区域和纵向上开辟深部第二找矿空间的找矿思路。
Yanling-Lanshan fault is a abyssal fault belt with a long activity time and large scale in south Hunan. It plays an important role to control the forming and distribution of regional ore fields. It controls the forming and distribution of W, Sn, Pb and Zn polymetalic ore belt in NE direction in Yanling-Lanshan region. It also controls polymetallic ore fields and nonferrous metal deposits of more than 80 percent in south Hunan. The fault is not only an ore-controlling fault, but also related to the ore-forming process and later reconstruction activity of the deposits. On the basis of the study of geophysical setting, geochemical feature, sedimentary lithofacies formation, structural and magmatic process and mineralization characteristics, the authors have proposed the exploration thought of two prospecting targets in landscape direction and the second mine space in the deep area.
