FORMATION OF SEDIMENTARY ROCKS
The particles that form a sedimentary rock are called sediment, and may be composed of detritus/minerals or biological detritus/organic matter. Thus, sedimentary particles or sediments are building blocks of sedimentary rocks. We can classify sedimentary particles into three groups: 1.

What are Igneous, Sedimentary, & Metamorphic Rocks?
Metamorphic Rocks. Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure).

As the tectonic plates converge, the sedimentary rock is subjected to higher pressures and temperatures, which can chemically as well as physically alter it into a metamorphic rock.
