摘要
在内蒙古阿拉善左旗嘎拉斯台地区开展 1∶5万土壤地球化学测量,对区内Au、Ag、Sn、Cu、Pb、Zn、Cr、Mo、Nb、Ni、W、Sb、Bi、La、Th、U、Y、As 18 个元素进行分析.圈定综合异常 30 处,其中铜铅锌银类异常 6 个,金砷锑类异常 9 个,钨锡钼类异常9 个,镍铬类异常3 个,稀土稀有类异常3 个.在综合异常特征解析基础上,结合区域成矿地质条件、成矿规律等因素,将研究区划分成 3 个A类Ⅴ级金、铜、镍、钨等多金属及稀有、稀土找矿远景区,为研究区后续找矿工作提供了思路.
Abstract
A 1:50000 soil geochemical survey was carried out in Galasitai Area,Alxa Left Banner,Inner Mongolia Autonomous Region,and 18 elements were analyzed which are Au,Ag,Sn,Cu,Pb,Zn,Cr,Mo,Nb,Ni,W,Sb,Bi,La,Th,U,Y and As.30 comprehensive anomalies were identified,including 6 copper,lead,zinc and silver anomalies,9 gold,arsenic and antimony anomalies,9 tungsten,tin and molybdenum anomalies,3 nickel-chromium anomalies,and 3 rare earth anomalies.On the basis of comprehensive analysis of anomaly features,combined with regional metallogenic geological conditions,metallogenic laws and other factors,the study area was divided into 3 class A potential prospects of grade Ⅴ gold,copper,nickel,tungsten and other polymetals and rare earth,which provided ideas for the future prospecting work in the study area.
