Study on the Prediction of Concealed Ores Body by Structural Deformation Lithofacies Traces Theory in Lanniping Copper Mine

针对老矿山隐伏矿体难识别、难发现定位预测的难题,通过多年在滥泥坪铜矿深、边部的找矿研究和实践,总结提出了构造变形岩相形迹学的研究内容和方法,首先对滥泥坪矿区构造岩相形迹填图,在此基础上,采用运动学和动力学研究矿区构造和岩体几何状况,恢复成矿构造动力学体制,分析成矿规律、矿体时空结构、岩相特征等,对矿区深部及外围隐伏矿定位预测及评价,提出重点找矿靶区。通过实践,认为构造变形岩相形迹学适于老矿山"边、深、新、空"隐伏矿体大比例预测的实用方法之一。

Aiming at the prediction problem that concealed ore-bodies is difficult to identify, difficult to find in old mines, through many years prospecting research and practices at deep edge part of Lanniping copper Mine, the research contents and methods of tectono- deformation- petrofacies- traces theory are put forward. First of all is mapping by geologic structures and lithofacies traces around Lanniping copper Mine, on this basis, mining area structures and rock mass geometric conditions are researched by kinematics and dynamics, so as to restore metallogenic tectonic dynamic mechanism, and analyze metallogenic regularities and ore body spacetime structure, lithofacies characteristics, etc, key prospecting target areas are proposed by orientation prediction and evaluation of concealed ores in the deep and periphery of mining area. By practice, it is considered that tectono-deformation petrofacies-traces theory is one of practical methods suitable for large scale prediction of concealed ores in the 'side, deep, new, empty' of old mines.
