道朗和都格地区重磁场特征与找矿远景区
GRAVITY AND MAGNETIC FIELD CHARACTERISTICS AND ORE-SEARCH PROSPECT DISTRICTS IN DAOLANG AND DUGE AREA
摘要
Abstract
Daolang and Duge area is a polymetallic ore-forming belt on the northern margin of the North China Plate. In order to forecast polymetallic distribution in this area, the authors employed such means as upward continuation, small subdomain filtering of the first vertical derivative and corresponding analysis of gravity and magnetic anomalies to process the 1 : 5 000 gravity and magnetic data. Characteristics of gravity and magnetic fields, residual gravity field, the first vertical derivative of gravity anomaly, correlation coefficient R of gravity and magnetic corresponding analysis and their relationship with the density and magnetic susceptibility of rocks and minerals were analyzed comprehensively. Combined with the regional geology and drilling data in this area, the authors delineated 5 faults, 11 ore - forming prospect areas, and analyzed the basis for delineation of faults and prospect areas comprehensively.关键词
