Another Van der Mineral

Content image: Another Van der Mineral

Just approved and pending publication here is news of yet another vanadate mineral, and this time by coincidence it has a "van" in the name.

Vandermeerscheite is a new mineral chemically similar to carnotite.

 

Vandermeerscheite K2[(UO2)2V2O8]·2H2O Monoclinic: P21/n
Carnotite K2(UO2)2(VO4)2·3H2O Monoclinic: P21/b

 

We will find out if it gets added to the carnotite group in due course.

The type locality for vandermeerscheite is Schellkopf, Brenk, Eifel, Rhineland-Palatinate, Germany.

It is interesting that the only other vanadium mineral discovered so far at Schellkopf is carnotite.

The picture shows the yellow colour and the association with phillipsite.

The mineral is understood to have been named for Belgian mineralogist Eddy Van Der Meersche, and author of the book Laacher See Minerals (1997) pertinent to the origins of vandermeerscheite.
