摘　　要：笔者通过大量地质、地球化学、球物理和矿床(点)资料研究,提出浙江省妙西多金属矿床成矿模型,该模型正在为普查项目所证实。妙西多金属矿矿床是典型的岩浆期后热液矿床,矿体主要受本区的三级构造即岩体接触带构造和地层不连续界面构造控制。地球物理测量提供的深部信息和地质构造标志是本区多金属矿直接找矿标志,地表物化探资料在普查工作中可以起辅助作用。This paper proposed a metallogenic model of Miaoxi polymetallic deposit in Zhejiang province by studying a lot of information about geology, geochemistry, geophysics and mineral deposits （ore occurrences）. The model is being confirmed in reconnaissance survey of mineral deposits. Miaoxi polymetallic deposit is a typical post-magmatic hydrothermal deposit, its ore bodies are controlled by contact structures of intrusive bodies and discontinuous surface structures in strata. The messages supplied from the depth by geophysic prospecting and the geological structure indicators are the direct prospecting criteria, while the surface geophysic and geochemical prospecting information might play an auxiliary role in reconnaissance survey.
