About Abhurite
Formula:
Sn21Cl16(OH)14O6
Colour:
Colourless
Hardness:
2
Specific Gravity:
4.42
Crystal System:
Trigonal
Name:
Named as a new mineral by Matzko et al. (1985), after its discovery locality, in the Sharm Abhur Cove, Jiddah (Jeddah), Red Sea, Mintaqat Makkah, Saudi Arabia. However, the mineral was first described by Griffin et al. (1977) as a new basic tin chloride found on pewter plates from a shipwreck off Hidra island, Norway. It was published, but not formally admitted to the IMA.
A tin hydroxychloride mineral.
This mineral is formed from the reaction of pure tin with sea water, and has exclusively been associated with tin ingots from shipwrecks. If discovered today it would be unlikely this would be accepted as a true mineral.
