Wairakite is one of the rarer zeolite species. It’s typically found around hot springs and forms white dodecahedral crystals similar to analcime. In this case, the white wairakite is completely replacing the elongated, stick-like crystals...
Green prismatic epidote with apparent paler tips, white prismatic flattened crystals of laumontite, and green platelets of pumpellyite. Small colourless quartz crystals. Width 9mm, stack of 78 images (epidote). Width 4.5mm, stack of 30 images...
