Encyclopedia
Hoelite is a mineral
, discovered in 1922 at Mt. Pyramide, Spitsbergen
, Norway and named after Norwegian geologist Adolf Hoel
(1879–1964). Its chemical formula is (C6H4)2(CO)2 or C14H8O2.
It is a very rare organic mineral which occurs in coal fire environments in association with sal ammoniac
and native sulfur.
Mineral
A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties. By comparison, a rock is an aggregate of minerals and/or mineraloids and does not...

Sal ammoniac
Sal ammoniac is a rare mineral composed of ammonium chloride, NH4Cl. It forms colorless to white to yellow-brown crystals in the isometric-hexoctahedral class. It has very poor cleavage and a brittle to conchoidal fracture. It is quite soft, with a Mohs hardness of 1.5 to 2, and has a low specific...
