摘要
豫西小秦岭地区太华杂岩中花岗质片麻岩为古老侵入岩，主要由黑云斜长片麻岩、黑云钾长片麻岩和黑云二长片麻岩等类型岩石组成，具有ＴＴＧ岩系的组成特征，元素地球化学特征反映其形成于类似现代板块碰撞带的构造环境．
Granitic gneisses within Taihua complex from Xiaoqinling area, Western Henan consist of biotite_plagioclase_gneiss, biotite_K_feldspar_gneiss and biotite_two_feldspar_gneiss. Their field relationship, petrography and geochemistry suggest that they are intrusions with geochemical features of TTG, formed in the modern_like plate collision zone.
