摘要
滇西盈江地区是近年来寻找离子吸附型稀土矿床的热点地区,通过近期1∶5万区域地质矿产调查,可以确定盈江地区离子吸附型稀土矿的成矿母岩为古近纪始新世5种类型的中酸性侵入岩,稀土矿均层赋存于这5种不同岩石类型花岗岩体的风化壳中,矿体厚2m^8m,一般在深度3m^6m范围内是稀土矿体赋存的最好部位。
The hot area in prospecting of ion adsorption REE deposit in recent years is Yingjiang in W Yunnan.According to the recent 1:50000 regional survey of geology and mineral resources,we have determined that Paleogene Eocene 5 types of intermediate-acid intrusive rock are the metallogenesis original rock of ion adsorption REE deposits in Yingjiang.The REE deposits are all in the weathering crust of these different granite bodies.The orebody is 2m-8m in thickness.In generally speaking,the best depth of REE deposit is 3m-6m.
