Description
The chemistry and intemal textures of alkali feldspar in quartz syenite from Oki-Dozen
island, Japan, are described together with the chemical compositions of coexisting hornblende,biotite and opaque minerals.The alkali feldspar shows complicated microtextures in thin section,consisting of two different areas,turbid and clear(non-turbid).The turbid areas show irregular mosaics of microperthitic texture,whereas the clear areas are either featureless or show various complicated textures such as wedge−shaped and ripple-like.As a whole,the feldspar consists microscopically of at least four different phases(areas)with different compositions.The problems on their formation are briefly discussed.
