摘要
云南陇川县浪达山-敢共山离子吸附型稀土矿床成矿母岩为白垩纪-始新世(似斑状)黑云母二长花岗岩。矿体赋存于全风化花岗岩及强风化花岗岩中,平面上呈面型展布;垂向上呈层状、似层状产出,具“弓背式”、“浅伏式”分布特征;属富镧钕低铕低钇的离子吸附型轻稀土矿床。区内花岗岩风化壳较发育,厚度大、含矿性好,具有较好的花岗岩风化壳离子吸附型稀土矿找矿前景。
The ore-forming parent rock of theLangdashan Gangongshan ion adsorption rare earth deposit in Longchuan County,Yunnan Province is the Cretaceous Eocene(porphyritic)biotite monzonitic granite.The ore body occurs in fully or strongly weathered granite,and is distributed in a planar pattern and in layered or layered like vertically,with the distribution characteristics of“arched back”and“shallow lying”.It is an ion-adsorption type light rare earth deposit,which is rich in lanthanum and neodymium,and low in europium and yttrium.The granite weathering crust in the area is relatively developed,with a large thickness and good ore-bearing property,which has good prospects for ion-adsorption rare earth mineral exploration.
