Sommaire: The closure of the iron and steel making plant at Consett in Durham in 1980 marked the end of an era—a long era in the world's iron and steel making history. Iron had been smelted in the Tyne- Wear area of the United Kingdom since before the Roman period, but apart from evidence of smithing in the Roman period, the historical evidence for iron production on a large scale dates from the 14th century.

Leuco-cratic fluorine- and boron-rich granites of the batholith exhibit many textural variations from aplite to pegmatite, but are dominated by a coarse-grained seriate unit and a fine-grained porphyritic unit.
Four distinctive tin vein occurrences within and near...
