Abstract

The k-feldspars in this granite have prominent perthitic intergrowths, which overprint obvious tartan and Carlsbad twins. Feldspars growth is more euhedral than that of other phases, though grain boundaries between feldspars are rather sutured. Anhedral riebeckite and biotite have seive-like textures. Olivine, if present, is found in trace amounts.
