新疆乌尔禾地区水系沉积物地球化学特征及找矿方向研究

    Study on the geochemical characteristics and exploration directions of water system sediments in Urhe Region, Xinjiang

    • 摘要: 乌尔禾地区位于哈萨克斯坦板块准噶尔微板块的西北缘,达拉布特断裂的东南侧。本文以研究区1∶5万水系沉积物测量的15种元素数据为基础,统计分析了研究区的元素富集特征、元素离散特征、元素相关性及元素地球化学场特征等,查明了单元地质体内的元素富集规律,同时利用变化系数大小对富集元素进行了成矿可能性预测。依据研究区地质背景和地球化学显示的元素组合特征,研究分析认为研究区金、铜、钼为主要成矿元素,其余元素为成矿指示元素和伴生元素。

       

      Abstract: The Urhe Region is located on the northwest edge of the Junggar Microplate of the Kazakhstan Plate, to the southeast of the Darabot Fault. Based on the data of 15 elements measured in the 1∶50000 water system sediments of the study area, the statistical analysis of the element enrichment characteristics, element dispersion characteristics, element correlation, and element geochemical field characteristics of the study area is carried out to identify the element enrichment patterns within the unit geological body. At the same time, the variation coefficient is used to predict the ore-forming possibility of enriched elements. Based on the geological background and geochemical characteristics of the study area, the study analysed that gold, copper, and molybdenum are the main ore-forming elements in the survey area, while the remaining elements are ore-forming indicator elements and associated elements.
