The quartz grains affected by outer environments in the processes of transport and sedimentation must be left some marks on their surfaces. The different sedimentary environments may have made the quartz grains different in shapes and surface characteristics. The sample, taken from three Tertiary sedimentary facies in Kuqa Basin, Xinjiang, are possessed of their own surface characteristics. The quartz grains from the lake facies commonly have on their surfaces silica precipitation and dish-shaped concavities, which represent desert environment,and the solution pits formed by later chemical corrosion,The quartz grains in the river facies generally have charactev0istics typical for underwater -ranport-V-form pit、Because of weakening of the waterpower, we can also observe the silica precipitation and secondary quartz crystal on their surfaces. In the littoral facies the quartz grains exhibied the laminated and stepped cleavabes, or solution brooves and pits as a result of the mechanical and chemi- cal corrosion.
