RM2497   Aluminium

Bulla Island, Caspian Sea, Gobustan, Azerbaijan

Small particles containing grains of native aluminum, an extreme rarity. In the images we can see that they are associated with magnetite. They most likely contain akdalaite, an oxide hydroxide of aluminum, which we have not confirmed due to the limitations of the electron microscopy technique. We will send report to the buyer.
The Bulla or Boulla is a mud volcano on the island of the same name, in the Baku archipelago, a few km SE of the city of Baku. The most intense eruptions occurred in 1857 and 1940, when erupting breccia volumes reached a few million cubic meters. The most interesting mineralization (native metals, akdalaite) is related to the ejection of the 1947 eruption.

Size: 1.8 x 1 mm.
