    When a mire starts to form, the first plants take root in underlying clays or sands that form the soil. Their rootlets are preserved beneath the coal seam as black carbonaceous markings, and the fossil soil in which they are found is called a seatearth (Figure 6). The presence of rootlets shows that the peat formed in situ, rather
