Nov 13, 2017· To a geologist or mineralogist, "silica" only means a SiO2 compound, regardless of its actual crystal structure. If you had pure SiO2 glass, you could describe it as being made of silica, and you can say that chemically, pure quartz is also SiO2. ...
Most high grade silica sand deposits occurs in form of sandstone formations that bounds the Arabian Shield to the north and east. Sandstone''s deposits are in general friable, loosely to moderately cemented and require pulverization to yield silica sand.

Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type;, a soil containing more than 85 percent sandsized particles by mass.
The grade of a typical heavy mineral sand ore deposit is usually low. Within the 21st century, the lowest cutoff grades of heavy minerals, as a total heavy mineral (THM) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade.
metamorphic and sedimentary (Ketner,1973; Bourne, 1994). While quartz deposits are abundant, and quartz is present in some form in nearly all mining operations, high purity and commercially viable deposits occur less frequently. The composition of silica sand is highly variable, depending on the local rock sources and conditions.

in sand dunes helps geologists to distinguish dune deposits from other landforms. Because quartz grains can form from a number of different rocks, the original source of the quartz dune sand cannot be singled out. It should be noted that relatively few bedrock outcrops occur in Michigan. Instead, glacial drift almost completely covers the State.
