====Surface texture====
Surface texture describes the small-scale features of a grain, such as pits, fractures, ridges, and scratches. These are most commonly evaluated on [[quartz]] grains, because these retain their surface markings for long periods of time. Surface texture varies from polished to frosted, and can reveal the history of transport of the grain; for example, frosted grains are particularly characteristic of [[Aeolian processes|aeolian]] sediments, transported by wind. Evaluation of these features often requires the use of a [[scanning electron microscope]].{{sfn|Boggs|2006|pp=68-70}}
