WebShale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated. WebApr 9, 2024 · The phyllite parent rocks are shale, pelite, or slate which further comes from a shale protolith. Shale can be transformed into schist, slate or genesis depending on the degree of heat and temperature. Similar to slate, phyllite has a typical texture known as phyllitic sheen and has the feasibility or tendency to split into sheets like slate rocks.
