AZOMITE® is a highly mineralized complex silica ore (Hydrated Sodium Calcium Aluminosilicate or HSCAS), mined in Utah from an ancient deposit left by an volcanic eruption that filled a small nearby seabed an estimated 30 million years ago. AZOMITE® is used as a naturally rich soil re-mineralizer for plants, as well as a feed ingredient for animals. In a typical chemical assay, AZOMITE® contains more than 70 trace minerals which include many rare earth elements (lanthanides). Many of these elements have been depleted from soils worldwide.
