滇东北多集中于大型铅锌银等多金属矿床的研究,待补地区研究程度相对较低.为了对会泽铅锌矿区外围,以及矿山厂—金牛厂断裂带的成矿条件进行综合异常评价,本次研究区选在待补区域进行1∶5万水系沉积物测量,并以所获得的数据为基础,分析水系沉积物的地球化学特征.根据元素组合特征及异常性质,结合异常区域的地质背景、成矿地质条件等因素圈定9个综合异常区.综合异常区具有较好的找矿潜力,为下一步找矿工作提供了依据.
The research carried out in Northeastern Yunnan is mostly about large-scale lead-zinc-silver polymetalic deposits,not paying enough attention to Daibu region.In order to make comprehensive anomaly evaluation of ore-forming conditions in Kuangshanchang-Jinniuchang fault zone and the peripheral of Huize lead and zinc mining area,the study conducted 1 ∶ 50 000 stream sediment geochemical survey in Daibu region,and based on that analyzed the geochemistry characteristics of the sediment.9 comprehensive anomaly targets were delineated according to element combination features and anomaly property,taking into consideration the geological settings and ore-forming geological conditions in the anomaly area.There are good prospecting potentials in the comprehensive anomaly area for future prospecting work.
