广东城口地区离子吸附型稀土矿矿床特征及找矿前景分析

Characteristics and prospecting prospect of ion adsorption rare earth deposits in Chengkou area,Guangdong Province

城口矿区属离子吸附型稀土矿,位于仁化县城北方向,地处湖南、广东两省的交界部位。区内地层不发育,构造以北东向为主,出露燕山早期和晚期花岗岩。矿床类型为风化壳离子吸附型稀土矿,规模已达中型。本文通过对城口矿区离子吸附型稀土矿成矿地质条件及矿床地质特征的总结,同时对该矿床的控矿因素进行了分析,得出了在城口地区具有花岗岩风化壳的地方还具有较大的找矿前景的结论。

Chengkou mining area is an ion adsorption rare earth mine,located in the north of Renhua county and at the junction of Hunan and Guangdong provinces.The strata in the area are not developed,and the structure is mainly NE trending,exposing early and late Yanshanian granites.The deposit type is weathered crust ion adsorption rare earth deposit,and its scale has reached medium.Based on the summary of the metallogenic geological conditions and geological characteristics of the ion adsorption rare earth deposit in Chengkou mining area,and the analysis of the ore controlling factors of the deposit,this paper concludes that there is still a great prospecting prospect in the area with granite weathering crust in Chengkou area.
