About Adanite
Formula:
Pb2(Te4+O3)(SO4)
Colour:
beige
Lustre:
Adamantine
Hardness:
2½
Specific Gravity:
6.385 (Calculated)
Crystal System:
Monoclinic
Name:
The mineral is named adanite in honor of American systematic mineral collector/ micromounter Charles (Chuck) Adan (b. 1961) of Salt Lake City, Utah, USA. Mr. Adan, a former President of the ‘‘Mineral Collectors of Utah’’ club in Salt Lake City, has self-collected most of his rare mineral collection. He is the discoverer of pararaisaite (Kampf et al. 2018a), northstarite (Kampf et al. 2020), and adanite (described herein), and he provided the holotype specimens for all three species.
Known synthetic analogue.
Not to be confused with adamite. Chemically resembles northstarite (which, however, is a tellurate-thiosulfate), schieffelinite, and to some extent also eztlite.
