山东首次发现离子吸附型稀土矿化体及其找矿意义
The First Discovery of Ion Adsorption Type Rare Earth Mineralization in Shandong and Its Prospecting Significance
摘要
Abstract
The first ion adsorption type rare earth mineralization body in Shandong Province was discovered in the Wujing fault zone.Through regional geological background analysis,on-site inspection,and sampling,comprehensive research and systematic analysis of the characteristics of the mineralized body:its occurrence and morphology are strictly controlled by the fault fracture zone,the overall direction is 20°,leaning towards the east,with an inclination angle of 70°,a length of about 2500m,and an average width of 20.53m;among the 50 samples tested,23 samples had light rare earth oxide content exceeding the cutoff grade and 3 samples exceeded the minimum industrial grade;the reason for this is that the Neoproterozoic diorite in the Wujing fault fracture zone has been exposed to long-term leaching from atmospheric precipitation and groundwater.The feldspar is completely hydrolyzed into clay minerals such as kaolinite,and the rare earth elements in the original rock are adsorbed on the surface of the clay minerals in an ionic state.This article analyzes and points out that the key location for mineral exploration in the region is the kaolin belt controlled by the Wujing fault zone,the prospecting indicators are divided into structural indicators,stratigraphic rock indicators,geophysical indicators,and geochemical indicators;The exploration type is an ion adsorption type light rare earth deposit.关键词
