基于GIS技术多源信息网格化成矿预测

Metallogenic Prediction of Multi Source Information Based on GIS Technology

大小柳沟铜矿区位于祁连山多金属成矿带的北西段,在总结该区成矿规律的基础上,基于Arc GIS软件平台,采取网格化的工作部署,针对每个网格要素单元,进行较系统的地质、地球化学、地球物理信息采集。在此基础上,建立该区多源成矿预测的空间信息数据源,通过GIS的空间分析功能进行多源信息的综合分析,根据各单元格信息量大小,区内圈定了3个成矿远景区。应用研究数据扎实,结论可靠,可指导该区进一步的找矿工作。

The Copper mining area in the Daxiaoliugou is located in the Qilian mountains polymetallic metallogenic belt in the north west, summarized the metallogenic regularities, based on the ArcGIS software platform, take the grid work of the deployment of each grid element unit based on geological, geochemical and geophysical information collection system. On this basis, the establishment of spatial information data source in the multi-source metallogenic prediction, comprehensive analysis using GIS spatial analysis function of the multi-source information, according to the cell size of the information area, delineated 3 mineralization. The application of the research data is solid and reliable, and it can guide the further prospecting work in this area.
