Description: Heulandite + Chabazite + Mesolite Moonen Bay, Isle of Skye, Scotland, UK 50mm x 30mm x 35mm high I was not alone on Skye on this occasion: my friend Dave found a small cavity full of 'mesolite' and when the 'mesolite' was washed off, some nice heulandite crystals appeared, accompanied by chabazite. A lot of the chabazite occurs as tiny crystals growing on the 'mesolite' needles, forming white globular masses. The main heulandite crystal measures 10mm x 8mm x 3mm thickness. Collected March/April 2013.
