Rock fragments will also remain where the rocks are not completely weathered. Not only is quartz the most stable of the common rock forming minerals in chemical weathering, its high hardness and lack of cleavage make it quite resistant to mechanical weathering.

Sands are loose, unconsolidated rocks having particle sizes between those of silt and pebbles (1/16-2 mm). When held together by chemical cement or by clay, they are called sandstones. These rocks result from the breaking down or weathering of older rocks and from the transportation and sorting of rock fragments by moving water or by wind.
