Early Mining: A Brief History • Lead Mining in the ...

Early Mining: A Brief History. Lead occurs within the rocks of the North East of England because of geological processes. Uplift and the movement of faults cause the limestone beds to crack. Mineral rich hot water is injected from deep within the crust and mantle into cracks in the crustal rocks and in particular the limestone rock beds.
