泰国哇伦矿区与老挝巴根矿区钾镁盐成矿特征对比及找矿分析
Comparison of metallogenic characteristics and Prospecting Analysis of potassium-magnesium salts between Wat Non mining area in Thailand and Pak Ngum mining area in Laos
摘要
Abstract
Wat Non mining area in Thailand and Pak Ngum mining area in Laos both belong to the Sakon Nakhon basin.Pak Ngum mining area belongs to the secondary basin(Vientiane basin)of the Sakon Nakhon basin;They are all three sedimentary cycles of evaporite and terrigenous clastic deposits,with similar sedimentary age,the same salt-forming geological background and salt-forming evolution type,and extremely similar potash-bearing salt deposit types and salt mineral assemblages.Through the exploration of potassium-magnesium salt deposits in the two mining areas,the geological characteristics and metallogenic regularities of the deposits are analyzed by the ore finding situation of boreholes,stratigraphic comparison and gravity survey data.During potassium salt deposition,they are independent potassium-forming sags,and the stratigraphic horizon and thickness of different sags are quite different.It is considered that the potassium-magnesium salt deposit in Wat Non mining area and Pak Ngum mining area are also controlled by the tectonic structure,and the deposit sequence has similar characteristics,which provides important guidance for the next step of potassium-magnesium salt exploration in the Wat Non mining area.关键词
