WebFeb 28, 2024 · Peat is an accumulation of partly decayed vegetation that has gone through a small amount of carbonization. However, peat is still considered part of the coal “family” because it contains energy that its original plants contained. WebAug 1, 1998 · Abstract. The peat-to-coal transition is commonly assumed to be accompanied by compaction that decreases the thickness of the organic deposit to values of 10% or less of the original peat thickness. Decompaction modeling using such values for coal seams in contact with penecontemporaneous channel sandstones leads to …
