| Abstract: | The granite gneiss found in the north side of the Shangxian Danfeng structural zone is a paleo intrusive in Ningshan Huxian area of Shaanxi Province. This paleo intrusive is mainly composed of the rocks of biotite anorthosite gneiss, biotite amphibole plagiogneiss and hornblende plagiogtneiss. It has the composition features of the TTG rock system. The element geochemical features indicate that it formed in a structural environment like to island arc. |
