豫西上宫金矿田地球化学三维特征研究

经过多轮矿产勘查工作,上宫金矿田累计探明金资源量已达超大型。文章利用上宫金矿田积累的大量勘查资料,建立了包括钻孔井位库、测斜数据库、岩性数据库和化验数据库等内容的钻孔数据库。从地球化学(原生晕)找矿方法入手,将传统的二维异常信息处理转变为三维异常信息处理,建立了上宫金矿田立体地球化学模型,并与区域地质、矿体、岩体、构造、地形等要素相关联,提取有利找矿信息因子,总结成矿规律和圈定找矿有利靶区。

Three-dimensional geochemical characteristics of Shanggong gold field in Western Henan Province

After many rounds of mineral exploration, the accumulated proven gold resources in Shanggong gold field have reached super-large scale. Based on a large amount of exploration data accumulated in Shanggong Gold Mine, a borehole database including borehole location database, inclinometer database, lithology database and laboratory database is established in this paper. Starting from the geochemical (primary halo) prospecting method, the traditional two-dimensional anomaly information processing is transformed into three-dimensional anomaly information processing, and the three-dimensional geochemical model of Shanggong gold field is established. It is associated with regional geology, orebody, rock mass, structure, topography and other elements, so as to extract favorable information factors for prospecting and summarize metallogenic rules. Laws and delineation of favorable target areas for ore prospecting.
