摘要
根据区内成矿区带的划分,依据1︰20万水系沉积物测量数据,统计计算了全区及各成矿区内元素背景值、平均值、区域浓集系数、变化系数等参数,阐明了成矿元素及伴生元素在全区及各成矿区的背景特征、富集变化及成矿特征、元素组合特征等。指出全区及各成矿区的主要富集成矿元素。
Based on metallogenic zoning in the district and 1：200000 stream sediments survey data, this paper made a statistic calculation of background value, average, regional enrichment coefficient and variation coefficient of elements in each metallogenic zone, this paper discussed the background feature, enrichment change, metallogenic feature and element association feature of ore-forming elements and associated elements in the district and each zone, and pointed out major enriched ore-forming elements in the district and each zone.
