摘　　要：位于湖南南部的姑婆山岩体北西侧侵入接触带受断裂构造控制明显,表现复杂多样,是该区钨、锡多金属矿床的主要控矿构造。根据接触带不同成矿区段的空间展布特点、构造变形和矿化蚀变特征,认为该区接触带构造是岩体侵位和区域应力双重作用的结果,并首次将该侵入接触带构造划分为3种类型,即侵入接触-断裂复合型、双侵入接触-断裂复合型以及捕虏体接触-断裂复合型。明确提出了侵入接触带构造控矿的观点,从而为进一步研究其成矿及控矿作用提供必要的理论依据。The main ore-controlling structure of tin, tungsten and other multi-metallic deposit is the complex and diversified intrusive contact structure located in the northwest of Guposhan pluton, southern Hunan Province. The analysis of the characteristics of its spatial distribution, deformation and alteration shows that this structure is formed as the result of emplacement of pluton intrusion and regional tectonic stress. This contact structure is subdivided, for the first time, into three compound types： intrusion with faulting, bi-intrusion with faulting and xenogenic inclusion with faulting. The idea that the intrusive contact structure controls the-body will provide theoretical evidence for the further research of mineralization and ore control.
