What is shale rock.
Aug 2, 2020 · Shale is the most common sedimentary rock, accounting for about 70 percent of the rock found in the Earth's crust. It is a fine-grained clastic sedimentary rock made of compacted mud consisting of clay and tiny particles of quartz, calcite, mica, pyrite, other minerals, and organic compounds.
Oct 9, 2019 · Shale can be fairly hard if it has a silica cement, making it closer to chert. Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate. Geologists have long known that shale rock formations contain large amounts of natural gas and oil, but the fossil fuel resources were trapped in layers of rock and could not easily be extracted. During the initial phase of the fracturing operation, a well is drilled vertically underground to a point past the deepest aquifer containing fresh groundwater.There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.
