摘要
故县水库—全包山岩石地球化学测量剖面位于豫西沙沟—龙门店Ag多金属矿矿集区内,在剖面中6.0-10.0km范围内新发现了Au、Ag、Cr、Co、Cu和Pb异常,其中Cr、Co异常为在沙沟—龙门店Ag多金属矿集区内寻找新矿化类型提供了重要信息。在透岩浆流体成矿理论框架下,岩石地球化学剖面测量结果不仅成为矿集区存在隐伏的与Ag多金属成矿作用相关的岩浆-流体活动(透岩浆流体作用)这一地质模型的又一新证据,而且也为在矿集区内寻找隐伏岩(矿)体(如剖面中6.0-10.0 km的深部)和新矿床类型(伟晶岩型Au矿床、斑岩型矿床)提供了重要的线索。
Geochemical rock survey section from Guxian Reservoir to Quanbao Mountain is located in the Shagou-Longmendian Ag polymetallic ore concentration area of western Henan Province.The obvious anomalies of Au,Ag,Cr,Co,Cu and Pb were found about 6.0km to 10.0km in length along the section.The anomalies of Cr and Co along the geochemical rock survey section are important clue to finding new type deposits.On the basis of the metallogenic theory on the transmagmatic fluids,the result of geochemical rock survey section from Guxian Reservoir to Quanbao Mountain becomes new significant evidence to prove the geological model of concealed magma-fluids interactivities（transmagmatic fluids） related to Ag polymetallic mineralization.The results obtained by the authors are important in search for concealed igneous bodies and ore bodies in the depth under 6.0-10.0km in geochemical rock survey section,and also of great significance in finding new type deposits,such as pegmatite-type Au deposits and porphyry-type deposits in the Shagou-Longmendian Ag polymetallic ore concentration area.
