Cobaltoan Calcite: A variety of Calcite containing Co2+ From Morocco

Good Morning, Friends…

Here we have PENTAGONITE, a rare hydrous vanadium silicate mineral with the chemical formula Ca(VO)Si4O10·4(H2O)

The term “Penta” comes from Ancient Greek and refers to “five”… having five or containing five…

Penta’s name association to this pretty mineral is due to its crystal twinning * which has a FIVE-fold symmetry / habit.

* Crystal twinning is the result of two separate crystals sharing
some of the same crystal lattice points in a symmetrical manner.
This results in an inter-growth of two separate crystals in a number of different forms.

Who noticed that the blue in pentagonite is very similar to that of cavansite? There is good reason for this.

They are POLYMORPHS of each other (same chemical composition, different crystal structure). The primary difference lies within the arrangement of the layers of silicate.

Cavansite forms as prismatic (resembling a prism) crystals, often as radiating clusters.

Interesting to note that both of these gorgeous blue minerals come from around the same area: Poona (aka Pune), India.

From the Wagholi Quarries (Pune District) of Maharashtra, India :


Fred. Pick up some the next time you are in Morocco; to go with my trilobites.. R
