河南省嵩县花山-合峪地区化探异常特征及找矿方向

CHARACTERRISTICS OF GEOCHEMICAL ANOMALY IN HUASHAN-HEYU REGION IN HENAN AND PROSPECTING ORIENTATION

花山 -合峪地区是内生贵金属—有色金属资源潜力较大地区 ,成矿地质条件优越。化探异常区面积约 130 0 km2 ,异常组分复杂 ,套合性较好 ,强度高。近二十年在对该异常区的勘查评价工作中发现了大量金、钼矿床 ,但区内尚有数十处含矿地质体需进一步普查评价。 w(Au)在 3× 10 - 9以上异常范围是寻找岩金的有利靶区 ,重点应在柿树府和前河异常区 ,同时注意在断裂交叉部位寻找岩金。砂金应在Au异常外带嵩县 -潭头盆地中寻找 ,龙王庙号异常区是寻找钼的有利靶区。龙王庙南部地区在找金、钼的同时 。

Huashan-Heyu region is of great potential for endogenetic precious metal-nonferrous metal mineral resources with favorable metallogenic condition. The area of geochemical anomaly zone is about 1300km^2 and the compositions of the anomaly is complicated with high intensity and coincided with each other. Though a great number of gold and molybdenum deposits have been found during last two decades there are still several tens of ore bearing geological bodies that need to be further evaluated. The anomaly of over 3×10^(-9) of w (Au) is the favorable target for rock gold exploration and the key areas are Shishufu and Qianhe anomaly zones and attention should be paid to the intersecting part of the fractures while placer gold should be searched in Songxian-tantou basin in the outer zone of gold anomaly and Longwangmiao anomaly zone is a favorable target area for molybdenum exploration. In south part of Longhuangmiao area attention should be paid to lead deposit while searching for gold and molybdenum.
