Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. [1]
Learn about shale, the most abundant sedimentary rock that forms from compacted mud. Find out how shale is used for oil and gas, brick and tile, cement, and more.
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, 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.
