Sandstone vs shale
Shale usually contains about 50% silt, 35% clay, and 15% chemical materials, many shales may also contain organic plant materials and fossils. Shale is characterized by thinly, laminated layers, representing successive deposition of sediments. Shale accounts for about 50% of all sedimentary rocks deposited on the Earth’s surface. Jan 4, 2018 ... When compared to other sedimentary stones like shale, the framework of the grains maintains the porosity through lithification and burial.Shale: Shale has specification for size, soundness, or abrasion resistance, and typically breaks down fairly readily. Shale’s availability and lowcost make it ideal for large fill projects. o. Pit-run: A minimally processed material usually excavated right from the ground. Varies widely in quality and typically only used for fill material. o

When muddy sediments are buried and compacted for a long time, they form shale. When shale is buried deeper, for a longer time, and heated by the Earth's crust, it forms slate. The qualities of shale and slate vary with the makeup of the original sediments, the degree of compaction, the amount ...given for the common igneous and metamorphic rocks and for sedimentary sandstone, shale, and limestone and summary data are given for other less-common rocks. Specific heats for rocks can be obtained from data on rock-forming minerals. It is anticipated that values of these thermal properties of rocks and minerals will be useful for Sedimentary Rocks Clastic: are formed from mechanical weathering,which breaks rocks into pebbles, sand, or clay particles.
