摘要
户撒地区稀土矿矿体赋存于中生代三叠纪粗粒二长花岗岩、中~粗粒似斑状二长花岗岩体风化壳中,岩体风化壳的第二层中等风化带和第三层强风化带是本区稀土矿的主要控矿层位;该区稀土矿的形成经历了风化分解→剥蚀搬运→淋滤迁移→吸附富集的反复成矿作用,属花岗岩风化壳离子吸附型稀土矿矿床;可采用地质测量→地球化学土壤测量→野外快速分析→工程控制→野外快速分析+实验室分析测试的找矿方法,来揭露圈定该区稀土矿体。
The orebody of REE deposit in Husa area is in the weathering crust of Mesozoic Triassic coarse grain adamellite,middle-coarse grain quasi-porphyritic adamellite. The 2^（nd） bed of middle weathering zone and the 3^（rd） intense weathering zone of rockbody weathering crust are the main ore control bed of REE deposit in this area.The REE deposit formation has experienced the weathering decomposition→disintegration transportation→leaching migration→adsorption concentration repeat metallogenesis,belonging to the ionic adsorption REE deposit of granite weathering crust,which can be prospected and outlined by geological survey→geochemical soil survey→field rapid analysis→engineering control→field rapid analysis＋Lab analysis teasting method.
