Heteromorphite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pb7Sb8S19
System:
Monoclinic
Colour:
Iron black
Lustre:
Metallic
Hardness:
2½ - 3
Name:
From the Greek ετερος for "different" and μορφή "form" in allusion to a proposed dimorph.
This mineral is an intermediate member of a homologous series. The thickness of a galena sheet in the structure determines the series member. A very rare mineral.

Feather ores ("plumosite" = jamesonite, boulangerite etc.) have often been mislabeled as heteromorphite; for discussion see http://www.mindat.org/forum.php?read,7,158675,158759#msg-158759

Classification of Heteromorphite

Valid - first described prior to 1959 (pre-IMA) - "Grandfathered"
2.HC.10c

2 : SULFIDES and SULFOSALTS (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.)
H : Sulfosalts of SnS archetype
C : With only Pb
3.6.20.3

3 : SULFOSALTS
6 : 2 < ø < 2.49
5.6.10

5 : Sulphosalts - Sulpharsenites and Sulphobismuthites (those containing Sn, Ge,or V are in Section 6)
6 : Sulpharsenites etc. of Pb alone
