| Abstract: | 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. |
