| 摘 要： | 首次汇集了陕西石泉-旬阳金矿带整装勘查区内7个图幅1：50 000水系沉积物测量18种元素（Au、Cu、Zn、As、Sb、Hg、Bi、Ti、V、Ag、Sn、Pb、W、Mo、Ni、Co、Cr、Cd）的测试数据，共包含数据点13 169个，数据180 944个，第一次建立了该勘查区的地球化学数据库。在此基础上，编制了233张各类地球化学系列图件，并建立了空间数据库。通过本数据集在区内共圈定各类单元素异常2 083处，其中金元素异常304处；圈定金找矿靶区10处，金成矿远景区12处；经过后期矿产综合检查，整装勘查区内共发现金矿产（点）53处，其中，中型规模金矿床8处，小型规模金矿床18处，金元素异常与金矿床（点）对应程度较好，矿致异常达189处，显示1：50 000水系沉积物测量是勘查区内较好的找矿手段之一。

| Abstract: | This paper describes the collection of measured and tested data of 18 elements (Au, Cu, Zn, As, Sb, Hg, Bi, Ti, V, Ag, Sn, Pb, W, Mo, Ni, Co, Cr and Cd) in the stream sediments of seven 1:50 000 map sheets in the integrated survey area of the Shiquan-Xunyang gold ore zone, Shaanxi, including 13 169 data points and 180 944 total pieces of data, and the establishment of a geochemical database in the survey area for the first time. Building on this, 233 sheets of a variety of geochemical maps are developed and a spatial database established. Within the database, 2 083 places of various single-element anomalies are delineated in the area, including 304 Au anomalies; 10 Au prospecting target areas and 12 Au prospective areas are delineated; with subsequent comprehensive checking of minerals throughout the integrated survey area, there are 53 Au deposits (points), including 8 medium-scale Au deposits and 18 small-scale ones, indicating that Au anomalies correspond well with Au deposits (points), and there are 189 places of mineralized anomalies, indicating that the measurement of 1:50 000 stream sediments is one of the best means of prospecting in the survey area. |
