Jun 20, 2023 · Shale Rock Facts. Shale is the most common stone found in the sedimentary rock family. It makes up about 70% of the earth’s outer crust. Shale Rocks are commonly referred to as Claystone because they are composed of mud and clay sediments that have accumulated over a long period of time. Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. Siltstone. Siltstone is a clastic sedimentary rock that formed from grains whose sized between that of sandstone and mudstone. It can found different environmental conditions different color and textures. Siltstone generally are red and gray color with flat bedding planes. Darker colored siltstone have plant fossils and other carbon-rich matter.Hampshire Formation - Interbedded red shale, red mudstone, and red to brown cross-bedded siltstone and sandstone; some thin green shale; greenish-gray sandstone and shale toward top; fragmentary plant fossils; thickness 1,400 to 2,000 feet in west, increases to 3,800 feet in east.Hello, I'm new here, so just chiming in.
