Alluvial deposits from Loch Torridon, Scotland

　　• Spectra from feldspar grain from Torridon with exsolution texture sandstone indicate rapid cooling of parent igneous rock.

　　• Host mineral and exsolved species can be identified chemically, using Raman spectroscopy, as alkali and plagioclase feldspar.

　　• Intergrown hematite and anatase, only identified through combined EDX/Raman, helps understand deposition mechanisms and environments.
