Shale is a laminated or fissile clastic sedimentary rock that composed of predominance of silt and clay other minerals , especially quartz and calcite. Characteristic properties of shale is breaks along thin laminae or parallel layering or bedding called fissility. It is most abundant sedimentary rock. The composition (silt and clay) of shale ...

Siltstone. A siltstone is a lithified, nonfissile mudrock. In order for a rock to be named a siltstone, it must contain over 50% silt-sized material. Silt is any particle smaller than sand, 1/16 of a millimeter, and larger than clay, 1/256 of millimeter. Silt is believed to be the product of physical weathering, which can involve freezing and ...Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud."

Sedimentary rock often contains fossils because it is formed differently. It consists of sandstone, limestone, or shale that was once mud or sand in which the bodies of dead animals settled. The temperatures and pressures that create sedimentary rock are much lower and don’t destroy fossil remains. For fossils to form, the parts of a dead ...
