Shale description
Slate was formed under low-grade metamorphic conditions— i.e., under relatively low temperature and pressure. The original material was a fine clay, sometimes with sand or volcanic dust, usually in the form of a sedimentary rock ( e.g., a mudstone or shale). The parent rock may be only partially altered so that some of the original mineralogy ...Slate is a fine-grained, metamorphic rock formed by compression of sedimentary shale, mudstone, or basalt. Gray slate is common, but the rock occurs in a variety of colors, including brown, purple, green, and blue. Slate consists mainly of silicates (silicon and oxygen), phyllosilicates (potassium and aluminum silicate), and …

Description. Ashfield Shale comprises black mudstones and grey shales with frequent sideritic clay ironstone bands.The thickness ranges between 45 and 64 metres. It is 20 metres thick at the Sydney Olympic Site. The chemistry of the rock is typical of shales, with high iron levels, and some iron sulphide and low calcium levels. The geology of the …Shale is a rock made mostly of clay, siltstone is made up of silt-sized grains, sandstone is made of sand-sized clasts, and conglomerate is made of pebbles surrounded by a matrix of sand or mud. Biologic Sedimentary Rocks: Biologic sedimentary rocks form when large numbers of living things die. Chert is an example for this type of rock, and ...Shale is a soft, brittle, fine-grained, and easily eroded sedimentary rock formed from mineral-rich silt, or mud, that was deposited in an aquatic environment, buried by other sediment, and compacted and cemented into hard rock. When exposed at the surface by erosion, shale weathers into thin layers called plates.

Shale has a particular connotation in people's minds. Back in the day when I was in school, our professors used the Ingram (1953) classification and told us that shales were fissile and mudstones were massive. Now we know that fissility has more to do with clay-content, diagenesis and weathering. ...

However, additional elements in the rock often give it different colors. For example, ferric oxides impart red, brown, or orange color. The exact color due to iron oxide depends on the type of oxide in the rock. Hematite (ferric oxide) gives a red color ...

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.11 Şub 2022 ... Shale gas is a form of natural gas (mostly methane), found underground in shale rock.
