摘　　要：为寻找研究区铬铁矿勘查方向,依托《新疆托克逊县乌尔沟地区1∶5万地球化学普查项目》,以磁法、电法勘探为主,重点查证了HS21号综合异常南部的铬矿化点,对其进行地球物理分析和地质解译。最终,在新疆托克逊县乌尔沟地区发现了长约1.5 km,宽30~250 m,面积约0.22 km2的基性-超基性岩体,在岩体内发现一条长约1 km,宽80~150 m的铬铁矿矿化带,矿化带内共发现大小矿(化)体14个;上述铬矿化点特征良好地对应了地球物理异常特征,推测深部发现更多矿体的可能性较大,是今后铬铁矿勘查的方向。Based on the 1∶50000 Geochemical Survey Project in Wuergou Area,Toksun County,Xinjiang,the magnetic and electrical exploration are used to find the exploration direction of chromite in the area.Especially,the chromium mineralization points in the south of HS21 comprehensive anomaly are mainly focused on and its geophysical analysis and geological interpretation are carried out.The results show that there is a basic-ultrabasic rock mass with 1.5 km long,30—250 m wide and 0.22 km2 in Wuergou area,Toksun County,Xinjiang.In this rock mass,a chromite mineralization belt about 1 km long and 80—150 meters wide containing 14 mineralized bodies of different sizes are found.All of the chromium mineralization point characteristics is in well agreement with geophysical abnormal characteristics,so it is speculated that more ore bodies maybe be detected in the deep rock belt and it is the direction of chromite exploration in the future.
