The available data on the effect of2.1.4.1 Material Composition. The matrix materials in the deformable porous media are made up of either one single mineral or several minerals. For example, quartz sandstones are mainly composed of quartz (SiO2), while greywacke is composed of quartz, feldspar, mica, clay, and other minerals. Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. [1] Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Medium-grained rocks composed mainly of sand are called sandstone, or sometimes arenite if well sorted. Sediment grains in sandstone can having a wide variety of mineral …In situ leaching (ISL) is becoming the main mining practice for sandstone-type uranium deposits in China.
