A crystal of analcime, euhedral and glassy, perched on slender needles of natrolite. Field of view: 2.8mm.
Within a cavity, very slender needles of natrolite, transparent colourless crystals of stilbite and cloudy-white laumontite crystals. Field of view: 5.5mm.
In a small cavity, cloudy-white laumontites among tiny translucent stilbite crystals and a few slender needles of natrolite. When first collected at the quarry, these laumontite crystals were clear and colourless. Field of view: 3.7mm.
