Inderborite

specimen number:
2354255

location:
Inder, Atyrau, Kazakhstan

description:
Colorless crystallized inderborite across the top of matrix. Good reference quality example for the species from the type locality. The specimen comes with a previous label from the collection of Jack Nieburger.

The Inder region in the Atyrau province of Kazakhstan is characterized by a prominent salt dome whose caprock hosts extensive and complex evaporite borate deposits. Discovered and heavily explored for its rich industrial mineral resources since the Soviet era, the area became famous as a major global type locality for rare borates. Among these unique discoveries is inderborite, a hydrous calcium magnesium borate mineral that forms transparent to translucent, colorless or white prismatic crystals within the saline caprock environment. Mineral collectors and researchers prize fine specimens from this locality due to their sharp crystal morphology and association with other rare borates formed in arid lacustrine evaporite settings.
