Shale.
They accumulate and gather up into thick layers, which with time get compacted and lithified to form sedimentary rock.
Firing clay is when a clay is fired in a kiln, this is to make the clay stay strong.
a clay slab is a slab made of clay
Clay is made of clay ...
There are different minerals present in each clay body. Red clay typically has a higher iron content than grey clay.
Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.
== Shale is a sedimentary rock, comprised of lithified mud and clay minerals.
Clay can turn into limestone through a process called diagenesis, where the clay particles are subjected to compaction and cementation, forming a new rock material. Over time, the minerals in the clay are altered and precipitate out to form calcium carbonate, which is the primary mineral in limestone.
Shale is formed from the compaction and cementation of fine-grained silt and clay particles. These particles are typically compacted in low energy environments such as deep ocean basins or lake bottoms, where they settle slowly over time and become lithified into shale.
Sedimentary rock can be formed from lithified sediments.
Some examples of lithified sediment are sandstone, shale, and limestone. Sandstone forms from grains of sand compacted together over time, while shale is formed from compacted clay and silt particles. Limestone is made predominantly of calcite that has accumulated and solidified in marine environments.
The bulk of oceanic crust is composed of the extrusive rock basalt, the remainder being lithified and non-lithified sediments.
Unconsolidated refers to rock or sediment material that has not been lithified, meaning it has not been compacted and cemented together. Unconsolidated materials are loose and can include things like sand, gravel, and clay.
Mud is lithified clays and silt.
the sediment is loosened
Clastic sedimentary rock.
Sedimentary: mainly lithified from sediments on sea or lake floors. Evaporites: salts deposited by evaporation of saline lakes in hot, semi-arid climates. Igneous: lava and ash from volcanoes. Mineral: limited to locality - precipitates from hot springs. Non-lithified sediments: sands, gravels, periglacial "head", glacial moraine and outwash deposits ("boulder clay" etc), loess
