1.4 - Sedimentary Rocks. Sedimentary rocks are formed via the breakdown and redeposition of other materials, often older rocks. Sedimentary rocks are classified by their dominant particle size (sand, silt, or clay) and their mineral composition.lassic sedimentary rocks (i.e., sandstone or shale) are composed of minerals, grains and rock fragments derived from older rocks; while biogenic sedimentary rocks are made up of shells, their recrystallized remnants (i.e., limestone) or plant fragments (i.e., coal).
Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma. Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals.
