摘　　要：本次利用1∶5万水系沉积物数据研究了扎赉特旗地区元素的分布特征,总结了区内主要成矿元素异常特征。根据地质背景和异常查证成果综合分析,认为二叠系四甲山组、高家窝棚组等含灰岩地层为有利成矿层位,北东向、北西向断裂构造为有利的控矿和容矿构造,区内的成矿类型主要为矽卡岩型,通常在燕山期、华力西期花岗(闪长)岩与二叠系含灰岩地层的接触带上形成矿化矽卡岩。优选了小巴彦胡苏、巴尔嘎斯台和哈尔朝楚三处A级找矿靶区,为进一步找矿提供了方向。In this study,the distribution characteristics of elements in the Jalaid Banner area were studied by using 1:50000 stream sediment data.Based on comprehensive analysis of the geological background and anomaly verification results,it is argued that the Permian Sijiashan Formation and Gaojiawopeng Formation containing limestone are favorable ore-forming horizons,the NE-,and NW-trending fault structures are advantageous ore-controlling and ore-hosting structures,skarn is the mainly mineralization type,and the mineralized skarn usually formed in the contact zone of the Yanshanian and Hercynian grano(diorite)with the Permian limestone-bearing strata.Three A-level ore-prospecting targets are given as Xiaobayanhusu,Baergasita and Haerchaochu,providing a direction for further ore-prospecting.
