| 摘 要： | 聚矿构造系统是控制成矿物质迁移富集成矿的复合构造系统.按其规模从大到小可划分为7个层次，按照成因类型不同，分为岩浆矿床、岩浆期后热液矿床、沉积-热水沉积矿床和变质矿床聚矿构造系统4大类.重点阐述了矽卡岩型铁铜等矿床、斑岩型与斑岩-矽卡岩型铜钼矿床、岩浆期后高温热液钨锡矿床、岩浆期后中低温热液金多金属矿床和热水沉积-改造型铅锌矿床聚矿构造系统的特征及其控矿规律.总结了聚矿构造系统发育的有利部位及标志，阐述了通过聚矿构造研究，综合运用地质、地球物理与地球化学相结合的方法和类比求异的分析思路，进行隐伏矿床(体)定位预测和寻求找矿突破的有效途径，并提供了可借鉴的实例.

Ore-Accumulating Structural System and Mineral Exploration |
| |
| Abstract: | The ore-accumulating structural system is a composite structural system which controls the migration and enrichment of ore-forming materials. The ore-accumulating structural systems can be divided into four genetic types: magmatic deposit structural system,magmatic hydrothermal deposit structural system,sedimentary-hydrothermal sedimentary deposit structural system and metamorphic deposit structural system. In this paper,the characteristics and ore-controlling regularities of the ore-accumulating structural systems for the skarn Fe-Cu deposits,porphyry and porphyry-skarn Cu-Mo deposits,magmatic hydrothermal W-Sn deposits,magmatic mesothermal-epithermal Au-polymetallic deposits,and hydrothermal sedimentary-reworked Pb-Zn deposits are discussed. it summarizes the indicators and favorable positions for ore-accumulating structures,and proposes the effective ways to explore concealed ore deposits (orebodies) through the study of ore-accumulating structures combining the geological,geophysical and geochemical methods as well as the analogy-seeking anomaly thoughts,and provides some examples for reference. |
