摘要
成矿地质体找矿预测理论与方法的创建为中国勘查区找矿工作提供了理论指导和方法遵循,已广泛应用于矿集区、老矿山深部与外围的找矿预测和矿产勘查中。在河南省银洞坡金银矿集区、甘肃省早子沟金矿、四川省拉拉铜矿集区等83个矿集区和168座矿山取得了良好的找矿效果。该理论方法的核心是构建成矿地质体-成矿构造和成矿结构面-成矿作用特征标志“三位一体”找矿预测地质模型。总结了应用成矿地质体找矿预测理论与方法开展找矿预测工作的流程和要点:开展预研究提出找矿思路,研究典型矿床确定主攻矿床类型;研究成矿地质体确定找矿方向,研究成矿构造与成矿结构面确定矿体赋存位置,研究成矿作用特征标志提供矿体赋存依据,构建找矿预测地质模型确定成矿作用中心;综合地质、物探、化探方法,预测深部矿体空间位置;探矿工程验证实现找矿突破。本次研究为找矿预测工作提供了思路和示范,为新一轮找矿突破战略行动提供了支撑服务。
The establishment of prospecting prediction theory and method of metallogenic geological body provides theoretical and methodological guidance for prospecting in the exploration areas.This theory was widely used in the prospecting prediction and mineral exploration of ore-concentrated areas and the deep and/or peripheral of old mines.In practice excellent prospecting effects have been achieved in 83 ore concentration areas and 168 mines such as Yindongpo Au-Ag ore-concentrated area in Henan Zaozigou Au deposit in Gansu Lala Cu ore-concentrated area in Sichuan and so on.The core of this theory is to construct a trinity prospecting prediction geological model namely metallogenic geological body metallogenic structure and metallogenic structural plane and metallogenic characteristics.The application main points of this theory are as follows.Firstly carry out pre-comprehensive research and typical deposit research and then put forward to the main type of deposit and prospecting ideas.Secondly construct prospecting prediction geological model to determine metallogenic center.It mainly includes studying metallogenic geological body metallogenic structure and metallogenic structural plane and metallogenic characteristics with aim to determine prospecting direction the location of ore-body and provide ore-body occurrence basis respectively.Thirdly integrated application of geophysical and geochemical exploration method to identify the location of potential validation engineering.Finally carry out prospecting engineering verification in the hope of achieving prospecting breakthrough.The core purpose of this paper is to provide ideas and demonstration for the prospecting prediction work and to provide support services for the new round of prospecting breakthrough strategic action.
