摘要
碰撞造山带是板块构造演化的关键区域,其板块俯冲、地壳折返、断裂活动等复杂构造过程,与金铜锑多金属矿成矿存在紧密内在关联。而地球物理勘探凭借对地下介质密度、磁性、导电性、弹性等物性差异的灵敏捕捉,成为“透视”深部构造特征与成矿耦合关系、精准定位矿化异常与矿体分布的主要技术手段。笔者旨在系统梳理碰撞造山背景下金铜锑多金属矿的成矿规律、地球物理响应机理及勘探技术进展,总结重力、磁法、电法与电磁法、地震等主流勘探方法的技术特点、适用场景与应用效果,提炼有效找矿技术组合,总结其当前面临的主要挑战与未来发展趋势,为同类矿床勘探提供理论参考与技术支撑,助力破解浅部资源枯竭背景下的深部矿产勘探难题。
Collision orogenic belts are key regions in the evolution of plate tectonics.Their complex tectonic processes,such as plate subduction,crustal underthrusting,and fault activity,are closely and intrinsically linked to the mineralization of Au-Cu-Sb polymetallic deposits.Geophysical exploration,by sensitively detecting differences in physical properties such as density,magnetism,conductivity,and elasticity of underground media,has become a core technology for decoding the coupling between deep structures and mineralization,as well as for accurately identifying mineralization anomalies and orebody distribution.This paper aims to systematically review and summarize the metallogenic regularities,geophysical response mechanisms,and progress in exploration technologies of Au-Cu-Sb polymetallic deposits in collisional orogenic settings.It elaborates on the technical characteristics,applicable scenarios,and application effects of mainstream exploration methods,including gravity,magnetic,electrical and electromagnetic,and seismic methods;refines effective ore-prospecting technical combinations;and summarizes the main challenges currently faced and future development trends.The review is intended to provide theoretical reference and technical support for the exploration of similar deposits and to help address the challenge of deep mineral exploration amid shallow resource depletion.
