矿田构造的解析是研究矿床成因、成矿规律及找矿预测的重要手段 ,也是遂昌银 -金矿田研究的一个较薄弱的环节 .将地质力学的体系分析与板块理论相结合 ,首先对矿田成矿地质特征作了简要描述 ,提出矿田内存在早、晚两期矿化作用 ,即 :吕梁期 (Ag -Au)和燕山期(Pb·Zn -FeS2 ,Au -Ag) ,并在此基础上 ,确立了矿田控矿构造体系为陡倾折面体系、格状叠改体系以及川字型断裂破矿体系 .然后 ,通过鉴定不同成矿期矿田所处板块环境 ,确立了控制矿田的区域应力场 ,进而分析了不同期控矿构造体系的板块驱动机制 .
The analysis of ore-field structure is an important means to study the genesis and metallogenic regularity of ore deposits and the prediction of prospecting, and it is also a weak link in the research of Suichang silver-gold ore field.Combining the system analysis of geomechanics and plate theory, This paper briefly described the geological characteristics of ore-forming and proposed the early and late stages of mineralization in the ore field, namely: Ag-Au and Yanshan Period (Pb-Zn-FeS2, Au-Ag) Based on this, it is established that the ore-controlling tectonic system in the ore-field is a steep tiling system, a trellis tectonic alteration system and a Sichuan-style fractured oreblasting system.Then, by identifying the plate environment in different ore-forming stages, Controlled the regional stress field of the ore field, and then analyzed the plate driving mechanism of the ore-controlling tectonic system in different periods.
