Geological Characteristics and Metallogeny of the Huaishuping Gold Deposit in Songxian County, Henan Province
摘要
Abstract
The Huaishuping gold deposit occurs in the fracture structure of the Jidanping Formation,Xionger group,Middle Proterozoic. The main ore-bearing structures are gentle-interlayer detachment fault,followed by steeply inclined incision faults. Ore body shape is simple, looking like beds, thin veins, lenticulars and pods. The ore body thickness and grade are relatively stable. Pyrite is the major gold carrier minerals,gold as an independent mineral existing in the minerals. There are three kinds of occurrences:intergrain gold,inclusion gold and crack-gold,dominated by the first one. Ore types include disseminated, veinlet disseminated and net vein. Gold mineralization has close relation with pyritization, silicification and K-feldspariza-tion. The ore-forming materials mainly came from the Taihua group. The ore deposit is closely related to the acidic magma intrusion activities in the gran-itoids of Yanshanian and is a tectonic alteration rock type gold deposit. The discovery of the Huaishuping gold deposit shows that it is possible to form a large gold deposit in the gentle detachment fault of the Xiong'er Mountains region.关键词
