The type of rock formed by mud or clay under pressure is called shale. Shale is a sedimentary rock that forms from the compaction of fine-grained sediments, primarily composed of clay minerals and silt. Over time, the pressure from overlying materials causes these sediments to lithify into a solid rock. Shale can also contain fossilized remains and is often significant in the study of geological history.
A metamorphic rock.
Slate is silt changed under pressure.
Rock can be changed into metamorphic rock by heat and pressure.
By the metamorphosis of limestone, marble is formed. By the thermal decomposition of limestone, quicklime is formed. Which process depends on the temperature and pressure.
metamorphic - formed when igneous or sedimentary rocks are put under extreme heat and/or pressure. igneous - volcanic rock (comes from a volcano) sedimentary - particles of rock/sand/shells/clay etc. 'gathered' to make a rock.

Granite, china clay is a by product of granite which means when granite is weathered and put under pressure china clay is formed . Hope this helps!
compaction!(:
Slate is silt changed under pressure.
Rock can be changed into metamorphic rock by heat and pressure.
Shale exposed to great pressure can form slate, a fine-grained metamorphic rock. The intense pressure and heat cause the clay minerals in the shale to recrystallize, resulting in a denser and more durable rock with distinct foliation.

Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.
Marble is a metamorphic rock because it is formed from limestone that has been squeezed under pressure.
Heat and pressure deep beneath Earth's surface can change any rock into metamorphic rock
Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.
