摘要

The Mesoarchean—Neoarchean deformed intrusive bodies had been blocked out from the former Archean Taihua Group in the Lushan area, Henan Province, which is composed of the Weizhuang Gneiss and the Yushuzhuang Gneiss, with degree of metamorphism reaching to amphibolite and locally granulite facies. Their geochemical characteristics indicate feature of alluminum-high gneiss, whose protolith were trondhjemite—tonalite—granodiorite (TTG rock series),so providing the evidence of Early Precambrian Granite—Greenstone belt in the area.
