Log Properties of Coal Successions containing coals were commonly developed in deltaic environments with clastic deposits of shales, siltstones, and sandstones, as well as occasional ironstones (typically siderite). Coal is a sedimentary rock formed from peat that has been subjected to temperature, pressure and microbial action over millions of years. Over time, coal progresses in rank from lignite, to sub-bituminous coal, to bituminous coal and finally to anthracite; a process known as coalification.Boxho et al. found that the MAC of bituminous coal decreased by 0.8% per degree Celsius [12]. Hofer et al. [13] and Bustin et al. [14] obtained values of 2.2% and 1–3%, respectively.
