Get Latest PriceSedimentary rocks are formed by the accumulation and subsequent consolidation of sediments into various types of rock. the key is the sediments. sediments are unconsolidated material and have different origins. ultimately, the origin of these sediments is the weathering, erosion andor the chemical breakdown of other rocks.
Read MoreCoal is a sedimentary rock of biochemical origin. it forms from accumulations of organic matter, likely along the edges of shallow seas and lakes or rivers. flat swampy areas that are episodically flooded are the best candidates for coal formation. during non-flooding periods of time, thick accumulations of dead plant material pile up.
