承德地区隐伏矿综合信息成矿预测
Metallogenic Prediction Based on Comprehensive Information for the Concealed Deposit in Chengde Area
摘要
Abstract
The Chengde area,Hebei is one of important metal ore concentration areas in China.More than 300 endogenous ore deposits,or mineral occurrences have been found in this area.Gold,copper and magnetite are its major mineral resources.The Fe-Ti-V reserves ranked second in China.For decades,these mineral resources have been fully exploited and utilized.At present,many of the recoverable reserves of mine have been depleted.In order to search for concealed ores,we used gamma-ray spectrometric survey data,magnetic survey data,gravity survey data,medium-high spatial resolution remote sensing image and geochemical data to study the deep and shallow structures,the spatial distribution of concealed rock mass and mineralization alteration based on the multi information integration technology.The integrated geological information prediction models of porphyry,skarn and hydrothermal types were established using analytic hierarchy process for Chengde area.Using the model,we completed the prediction of the ore prospecting area and target selection.We have determined 12 prospective districts,and selected 18 ore-finding target areas such as Xidashan,Shuiquanzi in Chengde area.In 4 of these target areas,mineralization is found,and Mo-Pb-Zn has reached production grade in Yingtaogoumen.关键词
