Beautiful Blue!

One mineral that is very abundant in Parys is pisanite, an iron-rich mineral found in pyrite-containing environments.In Parys pisanite occurs in many locations and takes various forms, from deep blue to blue-green and the very altered orange.

The images below show two of the current pisanite formations underground in Parys. Note now the relatively small stalagmites in the second one are themselves blue like the pisanite, rather than the typical orange/brown found elsewhere in the system.

Nothing to report on the microbiology as yet from Parys, but watch this space. Both myself and my host group here at Bangor University (BART) will be attending the UK Geomicrobiology Network meeting in Leeds on June 24th, where hopefully some results will be presented.

Even the stalactites are blue in this pisanite-dominated chamber
