摘　　要：魏家钨矿是近年来进行新一轮矿产远景调查时,在南岭成矿带北缘发现的又一大型钨矿。本文在讨论成矿地质背景基础上,对矿床地质特征进行了研究。矿体的空间展布受矿区内基底构造、岩性、祥林铺背斜、祥林铺花岗斑岩体以及铜山岭花岗闪长岩体往北东侵入的隐伏岩体控制。由于岩浆的二次侵位,形成二次成矿。矿床成因为斑岩-矽卡岩型钨矿床。同时指出了找矿标志,分析了找矿远景及今后工作方向,对以后的找矿工作有一定的指导意义。The Weijia tungsten deposit is another large-size tungsten deposit discovered recently during the new round of prospective survey for mineral resources on the northern margin of the Nanling Mountains.Based on a discussion on the metallogenic geological background,the authors studied the geological characteristics of the ore deposit.The spatial distribution of the ore body is controlled by the basement structure,lithologic character,Xianglinpu anticline,Xianglinpu granite porphyry and the concealed rock body resulting from the NE-trending intrusion of the Tongshanling granite porphyry.The secondary emplacement of the magma caused the secondary mineralization.The ore deposit is of porphyry-skarn type.In this paper,ore-prospecting criteria are pointed out,and oresearch prospects as well as direction for further work are analyzed,which is of some guiding significance for ore-prospecting work in the future.
