This has revealed that particles from both deposits have very fine (~lμ) particles adhering firmly to them. This was also observed in an artificial sample of finely ground quartz sand. It is suggested that the fine particles are comminution debris and that their presence points strongly to the loess quartz particles being formed by glacial grinding. Calcium carbonate appeared to form discrete overgrowths on the Karlsruhe particles rather than existing as a complete coating on the quartz grains. Some surface textures were observed on Nebraska grains which were very similar to those observed on desert sand grains. This content is PDF only. Please click on the PDF icon to access.
