河南省嵩县小南沟金矿是产于熊耳群火山岩中的构造蚀变岩型矿床,矿化受控于近南北向断裂构造,工业矿体主要产于其中NE 向的含矿断裂中。系统的矿床地质地球化学研究发现, 矿体横剖面和纵剖面上都存在明显的元素分带。纵投影剖面的地球化学反映出Au 、Ag 、Cu 、Pb 、Zn 、As 、Sb 和W 等元素均形成向上开口的“U”形,含量上高下低,向深部晕的规模逐渐减小,强度减弱,垂向上具有尾晕的地球化学特点。与Au 有关的元素以及热晕均显示出矿化主要集中于11 线以北及57 线以南地区,矿化富集地段集中于9~12 线多组断裂交汇部位。矿体向北侧伏,其原因是多组断裂的交汇部位形成一个向北侧伏的有利成矿空间。
The Xiaonangou gold deposit in Songxian County, Henan Province, is a tectonic alteration rock deposit that is produced in the Xiong’er Group volcanic rocks. Its mineralization is controlled by the nearly north-south fault structure. The industrial orebodies are mainly produced in the NE-bearing ore-bearing faults. Geological and geochemical study of the deposit shows that there are obvious elemental zonings on the cross section and longitudinal section of the ore body. The geochemistry of the vertical projection profile shows that U, Ag, Cu, Pb, Zn, As, Sb and W all form “U” shape with upward opening, Weakened intensity, the vertical halo with the geochemical characteristics. Au-related elements and thermal halo show that the mineralization is mainly concentrated in the area north of line 11 and south of line 57. The mineralized enrichment areas are concentrated in the intersection of 9-12 lines of multiple faults. The reason is that the ore body is volt- age to the north. The reason is that the intersections of multiple faults form a favorable mineralization space to the north.
