The lead, zinc and copper veins on Mendip were deposited by hot mineralising fluids typically between 50 and 150° C rising up from depth and depositing various minerals as they cooled. The source of the fluids were the deep sedimentary basins either side of the Mendips. As the Triassic and Jurassic sediments in these basins were buried, compacted and heated over time, some of the water in the rock was forced out, along with any diss

Lead ore ismonly found as lead sulphide PbS, galena, a heavy, shiny grey metallic ore with a conspicuous cubic cleavage, but locally pyromorphite, lead chlorophosphate Pb5PO43Cl, was worked on Green Hill, near Charterhouse and on Blagdon Hill. Around Charterhouse, the lead ore contained small amounts of silver. The lead ore occurs in two types of deposit: as primary lead ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary lead veins.See more on bgs.ac.uk

Galena is the main ore of lead, used since ancient times. Because of its somewhat low melting point, it was easy to liberate by smelting. It typically forms in low temperature sedimentary deposits.
In some deposits the galena contains about 12 silver, a byproduct that far outweighs the main lead ore in revenue. In these deposits significant amounts of silver occur as included silver sulfide mineral phases or as limited silver in solid solutionwithin the galena structure. These argentiferous galenas have long b

The mines at Leadhills were working lead ore by the mid thirteenth century, but most recorded activity in the 15th and 16th centuries relates to the search for gold, which was found in the local stream gravels. The Hope family acquired the land and minerals around the village in 1641 and took an active interest in lead mining there.

Lead has been mined in the limestone areas of the Peak since at least Roman times and continued until the last mine, Magpie mine, shut down in the 1950s. In geological times mineral rich magma was intruded into fissures and faults in the limestone.

The North Pennine fluorspar zone is centred on Weardale and during the 19th century the area supported a number of mines working this mineral, with lead ore as very much a by product. This industry died out in the 1980s as world prices fell and the national steel industry was reduced in

Lead mining has been taking place since the Iron Age. However, most mining took places during certain periods, particularly the Roman occupation, during the 17th and 18th centuries, and in the 19th century. Iron Age to Roman Times Mining on the Mendip Hills probably began in the late Iron Age.

Australias first metal mine was opened in 1841 at Glen Osmond, where lead ore was produced from the Wheal Gawler. However, South Australias current annual production 1998 of 3188 t of zinc and 15 t of lead is minor. Although PbZn mineralisation is widespread in a variety of geological environments, a major resource has yet to be developed in the State. Over 180 small deposits have
