Summary

[edit]
Description
English: Lee Moor China Clay Works. A view of the huge pit on the edge of Dartmoor from which clay is extracted. "Large parts of the granite body ... contain kaolinite derived from the alteration of the rock's feldspar component. It is now understood that this

is a result of a multi-stage process involving the alteration effects of both migrating superheated fluids and gasses which occurred soon after the granite was intruded, and later deep weathering caused by migrating lower temperature surface waters ... The hydraulic mining operations at Lee Moor {see 65094} were changed to dry mining techniques in 2001. Articulated trucks, working 12 hour shifts seven days a week, are used to haul the dry matrix (kaolin-bearing rock and associated waste rock) from the quarry face to the processing plant, where it undergoes similar processing as the wet workings" http://www.devon.gov.uk/amlp-ip37_lee_moor.pdf

The Lee Moor works, as run by Imerys, was to have closed, but "WBB decided it was still economically viable and is ploughing £6m into the pit and the surrounding area" http://news.bbc.co.uk/1/hi/england/devon/7083330.stm .
