Sillimanite is a metamorphic mineral. It occurs mostly in schist and gneiss. It may be present in lesser amount in some granites as an accessory mineral. As a sand grain it usually is accompanied by other metamorphic minerals like kyanite, staurolite, mica, and garnet. It is usually colorless or light brown in color.

What is Sand - Overview and Geology

Sometimes sand contains new minerals or mineral aggregates that were non-existent in the source rocks. Notable example is a clay mineral glauconite which forms in marine sand and gives distinctive dark green color to many sand samples. In some instances glauconite in sand may come from disintegrated glauconitic sandstone nearby, but eventually it is of marine

Silica sand - Sandatlas

30-12-2011 · If the particular sand deposit contains almost nothing but quartz, we often call it a silica sand. Such sand deposits are said to be mature because other rock-forming minerals are already broken down by the weathering process leaving only the super-resistant quartz as a residue. Silica sand is a mineral resource. It is mined mostly for glass ...

16.4 Glacial Deposition – Physical Geology

16.4 Glacial Deposition. Sediments transported and deposited during the Pleistocene glaciations are abundant throughout Canada. They are important sources of construction materials and are valuable as reservoirs for groundwater. Because they are almost all unconsolidated, they have significant implications for mass wasting.
