基于GIS技术的区域金矿资源定位预测流程——以藏北班公湖—怒江成矿带中段为例

The procedure of making location prognosis of regional gold mineral resources based on geographical information system(GIS) techniques——taking the middle section of Bangong Lake-Nujiang River metallogenic belt in north Tibet as example

以藏北班公湖—怒江成矿带中段为例 ,简要介绍了基于GIS技术的区域金矿资源定位预测流程。提出了定位预测流程的 3个重要步骤 :GIS图件库的制作→地、物、化、遥异常信息的提取→GIS区域金矿定位预测。研究认为 ,采用GIS技术预测 ,比传统方法更接近于实际 ,成果更可靠。

Taking the middle section of Bangong Lake Nujiang River metallogenic belt in north Tibet as example,the procedure of making location prognosis of regional gold mineral resources based on GIS techniques is briefly introduced.Three important steps to making location prognosis are put forward,i.e. the making of GIS map pool→the extraction of abnormal informations from geological,physical,chemical prospecting and remote sensing→accomplishing location prognosis of GIS regional gold deposit.It is considered that making location prognosis by means of GIS techniques is more practical and reliable than by traditional method.
