About Gramaccioliite-(Y)Hide

Carlo Maria Gramaccioli
Greasy, Sub-Metallic
Specific Gravity:
Crystal System:
Honouring Carlo Maria Gramaccioli (1935-2013), mineral collector and Professor of Physical Chemistry, University of Milan, Italy.
A member of the Crichtonite Group.

The yttrium analogue of senaite and the lead analogue of dessauite.

Classification of Gramaccioliite-(Y)Hide

Approval Year:

4 : OXIDES (Hydroxides, V[5,6] vanadates, arsenites, antimonites, bismuthites, sulfites, selenites, tellurites, iodates)
C : Metal: Oxygen = 2: 3,3: 5, and similar
C : With large and medium-sized cations

IMA Formula:

Crystallography of Gramaccioliite-(Y)Hide

Crystal System:
Class (H-M):
3 - Rhombohedral
Cell Parameters:
a = 10.411(3) Å, c = 20.97(3) Å
a:c = 1 : 2.014
Unit Cell V:
1,968.40 ų (Calculated from Unit Cell)
Six-sided tabular crystals (rhombohedral-pseudohexagonal), often with a strongly corroded appearance.
Cell refined from powder data; single-crystal data gave smaller parameters, a = 10.383, c = 20.882 Å (Orlandi et al., 1994). REE-rich material from Samos island has a = 9.1814(5) Å and α = 68.820(4)° (hexagonal setting: a = 10.377, c = 20.872 Å) (Theye et al., 2010).
