Applicability of quartz grains surface analysis to the study of the genesis of unlithified sediments
Abstract
Applicability of quartz grains surface analysis to the study of genesis of unlithified sediments. - This paper deals with genetic types of unlithified sediments and their characteristics with an emphasis on quartz grain surface microrelief. There are various physical-geographic agents in different sedimentary environments which play important role in the origin of certain marks on the surface of sedimentary grains.
That is why the study of features on quartz grain surfaces enables us to determine possible origin of sediments and landforms. Reference samples were chosen from geomorphological landforms of known origin: moraine in the Labský důl Valley, debris flow in the Důl Bílého Labe Valley, flood sediments and deluvium from the Důl Bílého Labe Valley in the Krkonoše Mountains and eolian sediment from Klárov in Prague.
There were found significant differences in surface micromorphology among these samples.
