Jul 1, 2024 · Apophyllite is commonly found in association with volcanic rocks, particularly in cavities or vesicles within basalt, andesite, or similar igneous formations. These cavities provide the ideal conditions for the formation of crystals, allowing for the growth of well-defined specimens.
Apophyllite is common worldwide in many basalt and diabase quarries, though large, well-formed crystals are limited to several important localities. By far, the largest crystals are from the Deccan Traprock s of India, and can be found in abundance in the zeolite -producing basalt quarries there.
These localities include: Jalgaon, India; the Harz Mountains of Germany, Mont Saint-Hilaire in Canada, and Kongsberg, Norway, with other locations in Scotland, Ireland, Brazil, Japan, and throughout the United States. Structure. Apophyllite has an unusual structure for a phyllosilicate.
Jul 3, 2024 · Where is Apophyllite found? Apophyllite is found in various locations around the world, including India, Brazil, Mexico, Canada, and the United States. It is often associated with volcanic regions and can be found in geodes or as individual crystals.

Mar 26, 2021 · Apophyllite crystals are being discovered from old lava flows that filled voids in which they are now hard masses. The cooled lava and the air bubbles resulted in hard pockets in the mass, which are called geodes. Apophyllite is typically clear, white, brown, pink, violet, yellow, and green.
Sep 26, 2022 · The mineral is usually found inside the once-open spaces (i.e. geodes, vesicles, cavities, cracks) of metamorphic rocks, spaces formed from gas bubbles while the lava cooled. You’ll usually see apophyllite inside lava rocks like basalt or trap rocks.
