摘要
本区位于南岭中段b-Zn-Ag-Sn-W-Mo-Bi-Mn-Cu-RM-REE-Mn成矿亚带内,东西向构造控制了燕山三期黑云母花岗岩的侵入,形成了沿东西展布的佛冈岩浆岩带,是稀土矿床形成的有利区域。本文通过比对来石稀土矿床、左坑稀土矿床和鱼湾稀土矿床的矿床特征和稀土配分类型,认为佛冈岩体为为离子吸附型稀土矿的形成提供了丰富的物质来源,区内含离子吸附型稀土矿化花岗岩风化壳极其发育,提供了较好的成矿条件,认为英德-佛冈-新丰地区具有较好的离子吸附型稀土矿找矿远景。
this area is located in the b-zn-ag-sn-w-mo-bi-mn-cu-rm-ree-mn metallogenic sub belt in the middle part of Nanling Mountains.The East-West structure controls the intrusion of biotite granite in the third stage of Yanshan period,forming the Fogang magmatic belt along the East-West distribution,which is a favorable area for the formation of rare earth deposits.By comparing the ore deposit characteristics and REE distribution types of Laishi REE deposit,zuokeng REE deposit and Yuwan REE deposit,it is considered that the Fogang pluton provides a rich material source for the formation of ion adsorption REE deposit,and the weathering crust of ion adsorption REE mineralized granite is extremely developed in the area,which provides a good metallogenic condition,It is considered that the Yingde Fogang Xinfeng area has a good prospecting prospect for ion adsorption type rare earth deposits.
