Sandstone. Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earth''s crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red

The lithology of the Lower Devonian is mainly quartz sandstone, fine siltstone, limestone, siliceous rock intercalated with shale, argillaceous siltstone, and black shale. In the upward direction, the gray and sandy matter are reduced, while the argillaceous matter is increased.
It usually develops in the upper part of mudstone on outcrops, interbeds with quartz sandstone in different thicknesses (Fig. 3B), or appears as a thin interbed between quartz sandstone layers, with a thickness of 2–3 cm, mainly light grey, medium-thick layer, fine-medium grain, with massive structure.
The fine-grained lithofacies include the fine sandstone, siltstone and shale of the alluvial fan deposits (Fig. 4G,I–K). They are reddish-brown or greyish yellow in colour, with layers ranging

The sandstone from the Oligocene Xiaganchaigou Formation (E3) in the Lengdong area, Qaidam Basin, China, is extensively distributed and acts as an effective regional reservoir for hydrocarbon accumulation. Based on thin sections, scanning electron microscopy (SEM), X-ray diffraction (XRD) image analysis and cathodoluminescence (CL), a comprehensive analysis of the sedimentology, petrography
sandstone, SEM, 1-4 microfractures, kern lithic quartz-sandstone, single polarizing. Fenggu Structure lays on the southern of inherited uplift belt of Western Sichuan Depression, China(Fig.1), performs as a NEE-trending nosing structure.
Some of these fractures are filled with calcite or quartz. The density of tectonic fractures in siltstone is the highest, followed by those in fine sandstones and medium sand; the fracture density of gritstone is the lowest (Fig. 4). With the increase of sandstone particle diameter, the density of natural fractures decreases.
Fine Buff Sandstone is a kind of beige sandstone quarried in China. This stone is especially good for exterior, wall cladding, paving and other design projects. It is also called China Buff Sandstone,Sichuan Buff Sandstone. Description Fine-grained sandstone without visible laminations. Durable with excellent weathering qualities.
Pore size and pore throat size distribution are acquired from mercury injection test. Porosity values range from 0.5% to 30%, and permeability ranges 0.006–7000 mD. Pore radii of coarse-grained sandstone and fine-grained sandstone range from 0.2 to > 4 µm and 1 nm to 1.60 µm, respectively, by MICP analysis.
