About Plumbonacrite
Formula:
Pb5O(OH)2(CO3)3
Colour:
Colorless to white
Lustre:
Pearly
Hardness:
3½
Specific Gravity:
7.07
Crystal System:
Trigonal
Name:
For the chemical composition ('plumbo') and the pearly lustre ('nacre').
A grandfathered species which was formerly not approved as a mineral. It was redefined and revalidated by the IMA in June 2012, with a newly defined type locality.
Plumbonacrite is closely related to hydrocerussite, but has a different chemical composition (less carbonate), unit cell and space group (P-3c1, Weil et al., unpublished data; note that the space group given in Krivovichev & Burns, 2000, is incorrect).
Plumbonacrite is also closely related to somersetite.
Visually very similar to Unnamed (Na-Pb Carbonate-Hydroxide II) (a slag phase).
Plumbonacrite has a narrow stability field (Taylor & Lopata, 1984).
