Formula:
NaMn2[Si3BO9](OH)2 · 2H2O
Original formula: Na(Mn,□)2[Si3(B,Si)O9(OH)2]•2H2O
Colour:
Colourless to pale green
Lustre:
Vitreous
Specific Gravity:
2.79 (Calculated)
Crystal System:
Triclinic
Name:
Named for Dr. Gert Nolze (b. 1960), a crystallographer at the Federal Institute for Materials Research and Testing (BAM), Berlin, Germany. Dr. Nolze, in conjunction with Dr. Werner Kraus, developed Powdercell (Kraus & Nolze 1996; currently in ver. 2.4), a program that has been extensively used in the calculation of powder X-ray diffraction patterns of minerals.
A pyroxenoid related to steedeite (its anhydrous counterpart) and the members of the pectolite-sérandite series.
Crystal structure details: (1) chains of tetrahedra (dreier type) with 3 independent SiO4 groups in C-shaped clusters; (2) BO2(OH)2 tetrahedra enclosing the clusters [(1) + (2) give dreier borosilicate chains]. Double borosilicate chains are formed by linking the single chains by MnO5(OH) octahedra.
Discovered by Col. Quintin Wight in August 1987 and was provisionally designated UK78
