The four corners represent the processes and factors that turn one type of rock into another: Weathering and erosion; Sedimentary ...Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.They conventionally are subdivided into categories based on mode of genesis. Structures that are produced at the same time as the sedimentary rock in which they occur are called primary sedimentary structures. …By. Andrew Alden. Updated on September 28, 2018. Lithification is how soft sediments, the end product of erosion, become rigid rock ("lithi-" means rock in scientific Greek). It begins when sediment, like sand, mud, silt and clay, is laid down for the last time and becomes gradually buried and compressed under new sediment.. Sedimentary rocks alongside the metamorphic and igneousSedimentary Rocks. Sedimentary rocks are formed a Chert is a broad term for chemically precipitated sedimentary rocks made up of microcrystalline silica. Most charts are nearly pure silica with up to 5% other minerals like calcite, dolomite, clay minerals, hematite, and organic matter. Some cherts may have up to 99% silica, while others have 65% silica content. Photographs and information for a large collection o Organic Sedimentary Rocks .
