MineralisationTypes of Lead OrePrimary Lead VeinsSecondary DepositsOrefieldsThe 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 dissSee more on bgs.ac.uk

Lead was the first metal mined in Australia at Glen Osmond in South Australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead zinc ore. In 1876, lead silver ore was discovered and mined at Thackaringa, near Broken Hill in New South Wales, but the mines closed in 1877. Partially eroded lead deposits exposed at the surface were relatively easily

Lead's per particle abundance in the Solar System is 0.121 ppb parts per billion. This figure is two and a half times higher than that of platinum, eight times more than mercury, and seventeen times more than gold. The amount of lead in the universeis slowly increasing as most heavier atoms all of which are unstable gradually decay to lead. The abundance of lead in the Solar System since its formation 4.5 billion years ago has increased by about 0.75 . The solar system abundances table shows that lead, d
