Magnesiobermanite (original) (raw)
A valid IMA mineral species
Formula:
MgMn3+2(PO4)2(OH)2 · 4H2O
Colour:
orange-red to brownish red
Crystal System:
Monoclinic
Name:
The magnesium analogue of bermanite, in which Mg replaces Mn2+ in the bermanite structure, hence the name.
The Mg analogue of bermanite.
Magnesiobermanite is structurally related to ercitite, mengeite and coralloite.
Magnesiobermanite was recently (2018) found on a specimen collected from the White Rock No.2 quarry in the 1960s.

Type Occurrence of MagnesiobermaniteHide
This section is currently hidden. Click the show button to view.
General Appearance of Type Material:
as twinned, bladed to tabular crystals, up to 0.3 mm long, forming aggregates up to 1.2 mm across. Magnesiobermanite occurs in cavities in a matrix comprising quartz and hydrothermally altered dark brown to black dufrénite-group minerals (dufrénite–natrodufrénite–gayite–bimbowrieite) that have nearly completely replaced earlier triplite.
Place of Conservation of Type Material:
Type material is deposited in the mineralogical collections of the South Australian Museum, North Terrace, Adelaide, South Australia, Australia, registration number G34762
