Sandstone is a clastic sedimentary reservoir rock composed of mainly quartz and/or feldspars, and typically deposited by relatively high-energy processes, which winnow out much of the fine particle size fraction while transporting and depositing the coarser (sand-sized) particles. Like sand, sandstone may be any color, but the most …

Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic …

Quartz sandstone: quartz sandstone in the Jinbaoshi Formation has a high frequency of development. It is mainly distributed with sections in Guangyuan and Jiange. It is usually expressed as interbedded thin siltstone and grey-green mudstone, thick sandstone intercalated thin siltstone, mudstone intercalated thin fine sandstone (Fig. 3 a).
