Shale is typically gray, black, or brown in color and may contain fossils, indicating it was formed in a setting that allowed for the preservation of organic material. How does shale form within the context of the rock cycle, and what are the environmental conditions that contribute to its creation?
21 Αυγ 2023 · Shales are fissile clastic sedimentary rocks formed from transportation, deposition and compaction of detrital materials of silt and clay. Fissility of the clay is its main distinguishing characteristic from other sedimentary rocks.
Shale is a fine-grained clastic sedimentary rock characterized by its fissility, shale readily cleaves into thin, typically less than 1 centimeter thick, laminae. Shale primarily composed of clay minerals, along with minor constituents like quartz and calcite.
Shale: Shale breaks into thin pieces with sharp edges. It occurs in a wide range of colors that include red, brown, green, gray, and black. It is the most common sedimentary rock and is found in sedimentary basins worldwide. What is Shale?
21 Νοε 2023 · Shale is a clastic sedimentary rock. This means shale is formed from clasts, or fragments or sediments that originate from a pre-existing rock that underwent physical weathering.
They are formed by the compaction and cementation of deposited material, or sediment. E.g. sandstone, limestone, shale Usually the sediment is fragments of other rock (clasts)
Shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth.
