Abhurite

Abhurite is a mineral of tin, oxygen, hydrogen, and chlorine with the formula Sn21O6(OH)14Cl16[4][2] or Sn3O(OH)2Cl2.

[5] It is named after its type locality, a shipwreck with tin ingots at Sharm Abhur, a cove near Jeddah in the Red Sea.

Abhurite forms alongside other tin minerals like romarchite and cassiterite.

[6] Abhurite can vary in color, from pale green/yellow to darker brown/green[7] Abhurite is attributed for forming on tin materials when in contact with sea water.

The mineral was described in 1977 from a shipwreck near Hidra Island, Norway, where it occurred on pewter plates.
