Crystal formation in minerals
WebApophyllite can be a beautiful mineral, forming in lustrous, transparent crystals that are well-formed and occasionally very large. Though it is found worldwide in volcanic zeolite environments, the Indian traprock quarries have produced enormous quantities of this mineral in all different shapes, sizes, and colors, making Apophyllite easily obtainable … WebMinerals play an important role in crystal formation but are not the only "ingredient" found in crystals. They are building blocks for crystals and they form crystals under specific conditions. For instance, the chemical …
