About PalmieriteHide

Luigi Palmieri

Formula:

K₂Pb(SO₄)₂

K may be replaced by minor Na.

Colour:

Colourless, white; colourless in transmitted light

Lustre:

Vitreous, Pearly

Hardness:

Specific Gravity:

4.363

Crystal System:

Trigonal

Member of:

Palmierite Group > Palmierite Supergroup

Name:

Named in honor of Luigi Palmieri (22 April 1807, Faicchio, Benevento, Italy – 9 September 1896, Naples, Italy), physicist and meteorologist, and Director of the Vesuvius Observatory. He was famous for his scientific studies of the eruptions of Mount Vesuvius, for his research on earthquakes and meteorological phenomena and for improving the seismograph.

Type Locality:

ⓘ Mount Vesuvius, Metropolitan City of Naples, Campania, Italy

Isostructural with:

Kalistrontite

The lead analogue of Kalistrontite. Compare eleomelanite.

In experimental volcanic gas condensation by Africano et al. (2002) it deposited in the range of ca. 600-400^oC.

Commonly found as an alteration product in man made pigments and smelting residues.
