About TubuliteHide

Formula:

Ag₂Pb₂₂Sb₂₀S₅₃

Colour:

Black

Lustre:

Metallic

Specific Gravity:

6.06 (Calculated)

Crystal System:

Monoclinic

Name:

Named after its characteristic tubular morphology.

Co-Type Localities:

ⓘ Le Rivet Quarry, Peyrebrune, Montredon-Labessonnié, Castres, Tarn, Occitanie, France
ⓘ Borgofranco Mines, Biò, Borgofranco d'Ivrea, Metropolitan City of Turin, Piedmont, Italy

A characteristic of this mineral is its peculiar tubular morphology. On the origin of the tubes, Moëlo et al (2014) propose that this is caused by capillary forces acting on very thin lamellar crystallites around gas bubbles or liquid droplets.

The unit cell of tubulite is very close to those of sterryite and parasterryite.

Compare 'UM1979-14-S:AgPbSb'.
