黔西南册亨百地金矿找矿模式初探
|
摘要
百地金矿位于南盘江—右江成矿带。研究区构造较复杂,各组断裂均具金矿化显示,但主控矿构造不清,深部及外围找矿方向亦不明确。通过深入总结百地金矿矿床地质特征、矿床地球化学特征、矿床地球物理特征及成矿物理化学条件,提出可能的成矿物质来源,厘定关键控矿条件,建立矿床找矿模式,提出在NW向、近EW向含矿断裂带往深部延伸矿体尖灭再现的可能性较大;深部T/P界面隆起部位有望发现似层状金矿体。
Baidi gold deposit is located in the Nanpanjiang-Youjiang metallogenic belt.The structure is complex in the study area and the gold mineralization occurs in the faults of each group.But the main ore-controlling structure is not found out,and the prospecting direction in the deep and peripheral areas is not determined out.On the basis of summary of the geological,geochemical and geophysical features and physicochemical conditions of Baidi gold deposit,the possible source of ore-forming material is pointed out,the key ore-controlling conditions are determined,and the ore prospecting model is established.It is suggested that the ore-bearing fault zones in NW and near EW direction are possible to extend to the deep area.The semilayered gold orebody is expected to be found out in the deep T/P boundary uplift.
