Abstract

The study was made in an attempt to differentiate between various modern environments using the natural surface features observed in quartz grains. Quartz grains from a number of recent environments (beach and nearshore, tidal flat and sabkha, coastal and inland dunes) were examined from Jeddah region. Different information is available concerning occurrence and distribution of chemical and mechanical surface features and their relationship to the different environments. Examination of quartz grain surface textures using the scanning electron microscope indicates that the transport and deposition in certain environments can be recognized by characteristic features.
