1830s exploration on Kilvey.Geologist Sir #WilliamLogan mapped the area to search out coal seams,seen as of national importance in the 1830s. Here's an extract from Logan's first map of #Swansea.The coal seams of the Hill were vital knowledge.We still have one of the rock exposures he studied to decide the position of the coal.There were no trees left so Logan could wander and search for coal and rock outcrops.Logan was the first to understand our coal seams. #KilveyHistory #GeologyHistory

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

#Swansea amateur geologist #MatthewMoggridge at a #PennantSandstone quarry on Swansea's Townhill in 1861.There were many quarries on the Hill providing building stone for houses in the west of the town and building of the South Dock and the River Tawe New Cut in the early 1850s.Matthew is standing next to some spectacular current bedding in the sandstone.He is holding his folding ruler, probably a Rabone model.As a geologist I'm sure he carried it around with him! #GeologyHistory #Carboniferous
