rapakivi texture
1.The Zhashui granite body, with typical rapakivi texture, is intruded into the nearby Shangdan suture zone of the Qinling orogen. A U-Pb age, that is 213. 6±1. 8 Ma and MSWD=1. 5, of zircons separated from the granite body was obtained in this paper. This result is the same as the U-Pb age of zircons, reported by the previous works, from the Shahewan rapakivi granite body in the eastern Qinling.
