浙江遂昌柘岱口-湖山断裂带活动期次与萤石成矿关系

遂昌柘岱口一湖山北东向断裂带在晚侏罗世至晚白垩世晚期经历了多期次、不同性质的活动，断裂活动与该地区两个大规模萤石矿田的形成关系密切。晚侏罗世晚期到早白垩世早期断裂活动表现为拉张松驰作用，为黄沙腰萤石矿田的形成提供了导矿和容矿构造空间，萤石矿主体赋存于北东向断裂带内。晚白垩世晚期，断裂活动表现为挤压环境，断裂带具有导矿作用，矿体受控于派生之北西向次级断裂内，湖山萤石矿田的形成具有此特征。

Relationship between fault activity and fluorite mineralization in Zhedaikou-Hushan fracture zone,Zhejiang

Zhedaikou-Hushan north-east strike fracture zone with several active stages possessed the characteristics of inherited basal structure from late stage of late Jurassic to late Cretaceous.The fracture zone underwent pull apart process,which provided tectonic space for the formation of Hushanyao fluorite ore field.The formation of Hushanyao and Hushan fluorite ore feild in this area is directly related to the conversion of the fracture zone,which not only serves as an ore lead, but also holds a capacity for ore. Based on the analysis of the specific characters of fracture zone ore control and the geological feature of ore body output,it can be deduced that Hushanyao fluorite ore field is mainly buried in the north-east strike fracture zone.In the late stage of late Cretaceous,fault activities occurred in the compressive setting.The main ore body was controlled by the derived north-west strike fracture zone.
