Aplowite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
CoSO4 · 4H2O
System:
Monoclinic
Colour:
Bright pink
Lustre:
Vitreous
Hardness:
3
Member of:
Name:
Named for Albert Peter Low (1861-1942), Canadian geologist and former director of the Geological Survey of Canada.
Rozenite Group. The Co analogue of rozenite, ilesite, etc. Chemically also analogous to drobecite (same point group, different space group).

It is a higher hydrate when compared to cobaltkieserite, and lower hydrate when compared to bieberite and moorhouseite.


Classification of Aplowite

Approved

7 : SULFATES (selenates, tellurates, chromates, molybdates, wolframates)
C : Sulfates (selenates, etc.) without additional anions, with H2O
B : With only medium-sized cations
