About NobleiteHide

Levi F. Noble
Formula:
CaB6O9(OH)2 · 3H2O
Colour:
Colorless, white
Lustre:
Sub-Vitreous, Pearly
Hardness:
3
Crystal System:
Monoclinic
Name:
Named in honor of Levi Fatzinger Noble (11 November 1882, Auburn, New York, USA - 4 August 1965, Los Angeles, California, USA), geologist with the United States Geological Survey (USGS). He made significant contributions to the geology of the Death Valley, the Grand Canyon, and the San Andreas Fault.
Crystal structure details/elements:
- fundamental building block (FBB) in the structure, that comprises three BO4 tetrahedra and three BO3 triangles
- 3 tetrahedra have one common corner
- six-membered B-O rings, formed by corner sharing involving tetrahedra and a triangle
- sheets || 100 plane are due to polymerization of the FBBs
- Ca cations: in the holes of the sheets
- water molecules: between the sheets
- CaO6(H2O)3 polyhedra, with the oxygen atoms belonging to FBB; the polyhedron is a distorted hexagonal bipyramid, in which one vertex is split
- hydrogen bonds: mainly between the sheets, bonds, involve all OH and H2O groups.
Nobleite is not isostructural with tunnellite.
