How it occurs in nature

This species has a documented chemistry and recognition record in the IMA catalog. The master list does not describe its formation environment. Consult the cited mineral-description studies below for species-specific occurrence and geological context; these cannot be inferred reliably from the formula alone.

Discovery & scientific record

The country refers to the master list’s first-discovery country, using modern borders. It is not a list of all deposits. A question mark is retained when the source is uncertain; a special-procedure date can refer to redefinition rather than discovery.

Catalog coverage and profile depth are different: every species in the cited IMA edition is indexed, but this edition does not provide every physical property or a full discovery narrative. The archive leaves those gaps explicit. Formulae and references are adapted from the IMA list under CC BY-SA 3.0; consult the original page for authoritative typography.
