About Glushinskite
Formula:
Mg(C2O4) · 2H2O
Colour:
Creamy white, colorless
Lustre:
Sub-Adamantine
Hardness:
2
Specific Gravity:
1.85
Crystal System:
Monoclinic
Member of:
Name:
Named in honor of Peter Ivanovich Glushinskii (Петр Иванович Глушинский) (1908–1990), coal geologist, Institute of Arctic and Antarctic Geology, St. Petersburg, Russia.
Type Locality:
Isostructural with:
The Fe analogue of lindbergite, andreybulakhite, humboldtine, and katsarosite.
Both alpha and beta forms are known as synthetic compounds.
Glushinskite is identical to the beta form.
The unnamed alpha form has been reported from the Lake Huleh basin, Jordan Rift Valley, Israel (Cowgill, 1989).
Common biomineral formed at lichen Lecanora atra - serpentinite interface (vide Burford et al., 2003).
