Overview

Excerpt from Special Reports on the Mineral Resources of Great Britain, Vol. 2: Barytes and Witherite Most of the North Of England spar occurs in veins traversing the upper strata Of the Carboniferous Limestone Series, with the important exceptions of New Brancepeth and Ushaw Moor, in which the Coal Measures form the country-rock. Around Wolsingham the country-rock invariably consists of the Millstone Grit, while the Cumberland veins traverse the Lower Palaeozoic rocks. On the whole, the barytes is of good quality, and in certain cases, of very high grade. Many of the mines have their own grinding-mills, and any bleaching required is confined to the small lump.
