This is Swansea coal from Kilvey Hill.Picked this up in the vicinity of the Swansea 2ft Seam.I was lucky to see coal deposits in the hole left after a Larch had blown down. Remarkable to see coal like this around Swansea nowadays.It looks like good quality bituminous coal. Close up you can see the bands of fusain, durain and vitrain as identified by expert palaeobotanist #MarieStopes in early 1900s.In the enlargement you can see the glassy layers. #KilveyHistory, #SwanseaHistory #GeologyHistory
