Maximum grain sizes range from 6.37 -22.45 mm (fine to coarse gravel). The range in maximum grain size for the rocks at lower elevations is narrower (~10-15 mm) compared …In order to be present in a sandstone as a lithic fragment, the grain size of the minerals in the lithic fragment must be smaller than the grain size of the sediment. Thus, granitic fragments will be expected to be rare, except in coarse sands, and volcanic and fine-grained metamorphic fragments will be expected to be more common.For example vfL sand ranges in size from 62 to 88 microns. Note that 1000 microns equals 1 millimeter. Thus, Cu sands range is size from 710 microns up to 1000 microns (or 1 m).

Conglomerate Breccia Sandstone Siltstone Shale Rock Name Crystalline LimestoneBreccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.

Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand [ 52 ]. Fine silt and clay can cross very long distances, even entire oceans suspended in the air.
