摘要
在河南灵宝县某金矿老区,根据成矿地质条件,用磁法、甚低频电磁法、瞬变电磁法、激电测深开展金矿找矿评价工作;在对地质、物探资料综合分析研究的基础上,根据综合物探预测找矿标志,在测区圈定出6个找矿靶区,经4个钻探孔验证均见到较好金矿,在小秦岭樊岔H8703含金断裂带浅、中部取得找矿突破,救活矿山一座。物探是经济、快速、有效地探测浅—深部隐伏、半隐伏盲矿体的主要方法之一,应当继续推广应用。
Magnetic method,very-low frequency electromagnetic method,transient electromagnetic method and IP sounding were employed to carry out gold prospecting and evaluation in an old gold ore district of Lingbao County,Henan Province,according to metallogenic geological conditions.Based on an integrated analysis and study of the geophysical data as well as the integrated geophysical prognostic criteria,the authors delineated six ore-prospecting target areas,which were proved to be related to gold mineralization by four drill holes.Ore-prospecting breakthrough was achieved in the shallow and middle parts of Fancha H8703 gold-bearing faulted zone of the Xiao Qinling Mountains,and a mine was brought back to vitality.It is proved that geophysical exploration is an economical,rapid and effective means in search for shallow and deep concealed or semi-blind ore deposits and hence deserves further popularized application.
