A PRELIMINARY ANALYSIS ON THE METALLOGENESIS OF GOLD DEPOSITS IN XIAOSHAN AREA, HENAN PROVINCE

Xiaoshan area, with a variety of mineral resources, is a significant metallogenic zone of nonferrous and precious metals in western Henan Province. The general tectonic framework is the Xiaoshan metamorphic core complex structure, with the core of metamorphic rock series of Taihua Group, surrounded by the volcanic rock cover of Xionger Group. The geological conditions are ideal for metallogenesis, with favorable ore-bearing rock series, developed ore host structures and great resources potential. The favorable strata, structures and magmatic rocks composite the ore-forming model for gold deposits, which would be a useful guide for the prospecting in the area.
