Floating mires may also produce low-ash peats, but these are thought generally to be of limited extent. Examination of modern delta plain peats show that they have an ash content of over 50% on a dry basis, and that peats with less than 25% ash on a dry basis rarely exceed 1 m in thickness. These peats if preserved in the geological record would form carbonaceous mudstones with coaly stringers. Studies of raised mires indicate that ash levels can be less than 5%, and over large areas may be as low as 1–2%.
Most modern peats are situated in low terrains not far above sea level. However, even in conditions of slow plant accumulation, peat can still develop in large quantities. Diessel (1992) quotes evidence that most Gondwana coal deposits were formed under cool to temperate conditions, whereas the European Paleogene–Neogene coal formations began in tropical conditions in the Eocene, changing to temperate conditions in the Miocene. A number of peat types have been summarized by Diessel (1992) as: 1.
Detailed interpretation of the sedimentary sequences exposed in outcrops, boreholes and in underground workings allows a facies model to be constructed, this in turn may help predict the orientation of washouts. Contemporaneous fault and fold inﬂuences during sedimentation can result in clastic wedges pinching out against these positive elements, with coal seams tending to merge over the structural highs. 20 Mapped lithotypes compiled from 1000 boreholes over an area of 1000 km2 , illustrating the regional depositional setting of the Beckley Seam, West Virginia, United States.
