摘要
锡矿山锑矿床是在伸展体制下（从白垩纪－老第三纪）由地下热水溶液循环而形成的低温热液矿床。伸展构造以浅层次的变形构造为特征，主要表现为正断层系加煌斑岩脉的组合型式，其对成矿具有重要控制作用。
The Xikuangshan antimony dePOsit in central Hunan was formed during theCretaceous to Paleogene.There exists a northwest-west to southeast-east directed stretchacross entire Hunan.In extension plays an important role the mineralization in inducingupper-crust-scale hydrothermal circulation,providing the conduits for transportation ofthe ore-bearing solution in the circulation,and making the necessary room for precipitation of antimony mineral from the fluid. Based on the correct reinterpretation of majorfaults as normal faults controlling the mineralization,the authors propose a new geneticmodel for the Xikuangshan antimony deposit.
