摘要:
燕山期花岗岩是华南花岗岩的重要组成部分，其不仅与华南多期多阶段的构造运动密切相关，同时也是引起区内钨多金属大规模成矿作用的主导因素。华南燕山期花岗岩与钨多金属成矿既有良好的时空关系，也有复杂的成因联系。本文根据前人的研究成果，总结华南地区燕山期花岗岩和钨锡等多金属成矿的基本特征及时空分布规律，探讨华南燕山期花岗岩及其与钨多金属成矿之间的耦合关系，认为：燕山期花岗岩浆活动不仅为钨多金属成矿提供充足的热动力来源，也保证了丰富的成矿物质基础，多数矿区的成岩与成矿作用近乎同时进行，且集中发生于160~150 Ma，是华南钨锡多金属成矿的高峰期。
Yanshanian granites, which are not only closely related to the multi-phase and multi-stage tectonic event in southern China, but also the leading factor in the large-scale multi-metal mineralization of tungsten in the region, are the main components of the South China granites. There is a good relationship between the Yanshanian granites and multi-metal mineralization of tungsten in time and space, and also complex genetic relation. Based on previous research results, this paper summarizes the basic characteristics and temporal and spatial distribution of Yanshanian granites and tungsten-polymetallic deposits, and discusses the coupling relationship between Yanshanian granite and tungsten polymetal minerogenic in Southern China, which indicates that the activity of Yanshanian granite magma activity not only provides abundant source of thermal power for multi-metal mineralization of tungsten, but also guarantees the rich ore forming material. The diagenesis and metallization in most of the mining areas work almost at the same time, and occur in 160 - 150 Ma, which is the peak of multi-metal mineralization of tungsten-tin in Southern China.
