滇东师宗-弥勒断裂带内以往地质研究程度较低,并且研究地区多集中于师宗-弥勒断裂带的东北端缘.本次研究是在1∶20万宜良幅和曲靖幅水系沉积物测量所圈定的远景区基础上,以树达棚-十字坡一带作为主要的研究区,对1∶5万水系沉积物测量所获得的数据进行分析研究.通过分析水系沉积物的元素特征值,包括平均值、变化系数、浓集克拉克值及元素组合分析.在以Au为主的单元素异常图的基础上,根据组合特征、异常性质,结合异常区域的地质背景、成矿地质条件等因素进行圈定综合异常,共圈定HS1-乙、HS2-甲和HS3-乙三个综合异常区.异常区中Au的异常值较高,分带性较好,具有较好的找矿潜力,为下一步工作提供了依据.
The past geology studies in the Shizong-Maitrei fault zone in eastern Yunnan are relatively low, and the study areas are mostly concentrated in the northeast edge of the Shizong-Maitrei fault zone.This study was conducted on the sediments of 1: 200000 Yiliangtun and Qujingjiaoshui Based on the measurements of the forested area, the data from 1:50 000 sediments of the water system are analyzed and studied based on the tree-shelf-cross slope area.On the basis of analyzing the elemental eigenvalue of the sediments, Including the average value, the coefficient of variation, the concentration of Clarke value and elemental combination analysis.Based on the single anomaly map with Au as its main component, according to the characteristics of the combination, the anomalous nature, the geological background of the anomaly region, the geological conditions of mineralization and other factors A total of delineation of a comprehensive delineation, a total of delineation of HS1-B, HS2-A and HS3-B three comprehensive anomaly area abnormalities in the Au higher anomalies, zoning is better, with good prospecting potential for the next Provide a basis for further work.
