Amphibole, Tridymite, and Pseudobrookite from Wannenköpfe Quarry, Germany

Amphibole, Tridymite, and Pseudobrookite from Wannenköpfe Quarry, Ochtendung, Maifeld, Mayen-Koblenz, Rhineland-Palatinate, Germany

Bit of a mouthful that. This is a nice micro specimen of mixed minerals - amphibole, pseudobrookite, and tridymite from the Wannenköpfe Quarry, Germany.

Magnification is essential for this specimen; the area of mineralisation is less than a centimeter across.

Looking at the magnified image we can see the three minerals - straw-yellow crystals of amphibole, white/clear six-sided plates of tridymite, and a single small crystal of gun-metal grey pseudobrookite. Almost certainly some other minerals on this matrix, but I've only identified the three.

This specimen comes boxed with our ID label.
