矽卡岩矿床一直是国内外矿床学研究的重点。重要科学问题，如不同类型矽卡岩矿床的成因机制有何异同？其主要控制因素是什么？等，值得深入探讨。本项目以浙西北安吉多金属矿区的矽卡岩型Fe-Zn-Cu和Pb-Zn-Ag-Cu矿床为研究对象。在详细的野外和室内研究及已有研究成果的基础上，拟通过Ar-Ar法定年、矿物和流体包裹体微区原位LA-ICP-MS成分分析、流体包裹体显微测温和H-O同位素示踪等方法，对两套矽卡岩矿床的形成时代、矿物化学特征、成岩成矿的物理化学环境、成矿流体的特征-来源-演化以及成矿元素的迁移沉淀机制进行对比研究，旨在解析两套矽卡岩及对应成矿金属元素组合的成因机制和主要控制因素，精细解剖不同类型矽卡岩矿床的形成过程，揭示其成矿地质构造背景。

Skarn deposits have been the subject of numerous studies at home and abroad over the centuries. Some scientific questions, such as what is the difference in the genetic mechanism and what are the major controlling factor of the different skarn deposits, are worth deeply discussing. This project focuses on the Fe-Zn-Cu and Pb-Zn-Ag-Cu skarn deposits in the Anji polymetallic ore district, northwestern Zhejiang Province, to discuss those scientific problems. On the basis of detailed field investigations, observations on thin sections and previous studies, systematic mineralogy, Ar-Ar dating, in-situ LA-ICP-MS analysis of the typical skarn minerals and single fluid inclusion, microthermometry and H-O isotopic tracing will be used to comparatively study on metallogenic epochs, mineral chemistry and the physical-chemical environment of those deposits, the characteristics, origin and evolution of ore-forming fluids, and also the migration and precipitation mechanisms of the metals. All those studies are with the aim to analyse and reveal the genesis mechanism and major controlling factors of the Fe-Zn-Cu and Pb-Zn-Ag-Cu skarn deposits, and also to accurately understand the ore-forming processes and tectonic setting of those skarn deposits.
