The
mineral is dedicated to H. Jordan (1808-1887), professor in Salzburg (Austria).
Jordanite is monoclinic, although sometimes form apparently hexagonal crystals
(known as pseudohexagonal) of considerable dimensions (crystals have been found
up to 5 cm, while the norm is 2-3 mm). They’re gray-lead tabular crystals,
frequently twinned in layers of different brightness, which alternate on the
faces of the individual crystal.
The crystals, which are often rounded, are often
associated with sphalerite, galenite, goyazite, dufrénoysite and lengenbachite;
much more rarely are associated with realgar. Lately, jordanite has been found
in other Binntal dolomites, such as in Messerbach and Reckibach.
