About PolariteHide
This section is currently hidden. Click the show button to view.
Crystal System:
Orthorhombic
Name:
From the type locality in the Polar Urals.
Note: New analyses of the holotype sample of borishanskiite, defined as "Pd1+x(As,Pb)2 , x = 0-0.2" (IMA no. 1974-010), show that this mineral is identical to polarite (IMA no. 1969-032).
Compositional similarity to, e.g., urvantsevite and 'UM1981-02-Bi:AsPbPd'.
