陕南化探数据库的建设及开发应用

CONSTRUCTION, APPLICATION AND DEVELOPMENT OF GEOCHEMICAL EXPLORATION DATABASE IN SOUTHERN SHAANXI PROVINCE

利用现代化计算工具及《区域地球化学数据管理系统》、MAPGIS地理信息系统等软件,对陕南地区57357km2历年来1∶5万化探数据进行建库、数据处理及成图,提取有用信息,分析研究陕南地区区域地球化学特征及各元素富集规律。结合地质、物探资料及时指导找矿预测、资料二次开发及二轮找矿。

A database was established for 1∶50 000 geochemical data from an area of 57 357 km^2 in southern Shaanxi Province on the basis of regional geochemical management system software and MAPGIS Geography Information System (GIS) software. At the same time, data processing and mapping were performed by means of the database. With the useful information extracted, the characteristics of the regional geochemical field and the enrichment regularity of some elements in southern Shaanxi Province can be studied and analyzed. Combined with geological and geophysical data, the database is helpful to ore prognosis and the second round of ore prospecting.
