对戛勒赛地区1∶5万水系沉积物测量及原岩元素含量测试数据的统计分析,共圈定综合异常9处。异常主要分布于二长花岗岩与下元古界金水口群地层接触带及金水口群内,矿体多产于二长花岗岩、二云石英片岩及透闪大理岩中。综合异常区内W、Sn元素间套和好,且浓集中心一致,浓度分带明显。区内具备寻找隐伏-半隐伏中高温热液金属矿产的条件,是寻找钨锡矿产的较佳区域。 A total of 9 comprehensive anomalies were delineated by the statistical analysis of 1:50 000 sediments and original rock elemental contents in the 1 000-water system in Zarzales. The anomalies are mainly distributed in the contact zone between the monzonitic granite and the Jinshuikou Group of the Lower Proterozoic and the Jinshuikou Group. The orebodies are prolific in the monzonitic granite, diurnal quartzite schist and the permeable marble. In the comprehensive anomaly area, the W and Sn elements are intercalated and well concentrated, and the concentration centers are the same with obvious concentration zonation. The region has to find the hidden - semi-buried high temperature hydrothermal metal mineral conditions, is to find a better tungsten-tin area.
