About BaumhaueriteHide

Heinrich A. Baumhauer

Formula:

Pb₁₂As₁₆S₃₆

Simplified Pb₃As₄S₉. May contain minor Sb substituting for As.

Colour:

Lead-grey, steel-grey; iridescent at times

Lustre:

Metallic

Hardness:

Specific Gravity:

5.33 - 5.44

Crystal System:

Triclinic

Member of:

Sartorite Group

Name:

Named in 1902 by Richard Harrison Solly in honor of Heinrich Adolf Baumhauer [October 26, 1848 Bonn, Germany - August 1, 1926 Fribourg, Switzerland], Professor of Mineralogy, University of Fribourg, Switzerland.

Type Locality:

ⓘ Lengenbach Quarry, Fäld, Binn, Goms, Valais, Switzerland

Compare argentobaumhauerite (formerly 'baumhauerite-2a') and bernarlottiite (Sb-rich); also 'UM1966-04-S:AsPb'.

The structure contains isolated and interconnected AsS₃ pyramids, as, e.g., in case of dufrénoysite, gratonite, sartorite, and seligmannite.
