摘要
云开成矿带是华南地区的一个重要的有色金属和贵金属成矿区带,位于其核部的罗定盆地为白垩纪陆相断陷盆地,其周边受断裂及岩浆活动的影响,形成了大量的金属矿产资源。围绕这个中生代断陷盆地,主要从其地质特征、形成机理及周边断裂、岩浆岩及成矿作用的关系等方面分析,认为罗定盆地周边的矿床成矿与构造、特别是深大断裂的控矿及岩浆活动有密切关系,区域化探异常能圈定找矿靶区。
The Yunkai metallogentic belt is one of the important metallogentic belts of nonferrous and noble metal deposits.The Luoding basin,which is Located in its nuclear department,belong to cretaceous continental fault basins.And the surrounding of the basin formed lots of metal mineral resources under the influence of fault structures and magmatic activities.The paper focus on the research of the interaction in geological factors of Mesozoic fault basin,such as geological characteristics,formation mechanism,surrounding fault structures,Magmatic rocks and mineralization。Based on the comprehensive analysis,the main conclusions are listed as follows;Mineralization of Deposits around the Luoding basin has a close relationship to geologic structure,especially mineralization deep faults and magma activity.And regional geochemical anomalies can help us to circle the prospecting target area.
