WebShale is formed from tiny particles of clay with some quartz and occasional decaying algae at the bottom of slow moving rivers. This gives the shale a layered structure and the trapped algae... WebWhen muddy sediments are buried and compacted for a long time, they form shale. When shale is buried deeper, for a longer time, and heated by the Earth's crust, it forms slate. The qualities of shale and slate vary with the makeup of the original sediments, the degree of compaction, the amount of heat and the ...
WebSlate is composed mainly of clay minerals or micas, depending upon the degree of metamorphism to which it has been subjected. The original clay minerals in shale alter to micas with increasing levels of heat and … Web23 jul. 2024 · How is slate formed? 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).
