New method of structural analysis and measurement of V-shaped percussion cracks in quartz sands surface by confocal laser scanning microscope (CLSM).

Microtextures of quartz sand grains can be used to establish sedimentary provenance of sedimentary deposits. V-shaped percussion cracks (Vs), which are randomly produced by grain-to-grain mechanical collision in high-energy subaqueous environments, are significant microtextures used for investigation of fluvial and marine sediment. In previous studies, others have used the percentage of microtextures obtained by scanning electron microscope to compare sediment samples.
