Roundness and surface features of quartz grains in Middle Devonian deposits of the East Baltic and their palaeogeographical implications
East Baltic Devonian roundness of detrital particles surface texture of quartz
2009/10/21
The roundness and surface texture of quartz grains were studied in Devonian sediments of 32 drill cores. Roundness was estimated in more than 800 samples and surface textures were examined under scann...
