Azomite
Azomite (pronounced ā-zō-mite, officially all-caps AZOMITE) is the registered trademark for a complex silica ore (hydrated sodium calcium aluminosilicate) with an elevated ratio of trace minerals unique to the Utah mineral deposit from which it is mined. When the ash from a volcanic eruption filled a nearby seabed an estimated 30 million years ago, the combination of seawater, fed by hundreds of mineral-rich rivers and the rare earth minerals present in the volcanic ash, created the deposit’s distinctive composition. Mineralogically described as rhyolitic tuff breccia, the geologic characteristic of its surface is referred to as an outcrop known as a hogback. == Scientific analysis == Scientific analysis of this combination of volcanic ash and marine minerals reports over 70 trace minerals, many recognized as essential by the National Research Council of Canada. A typical analysis of an Azomite sample using spark source mass spectrometry reveals the presence of many rare earth elements.〔(【引用サイトリンク】url=http://azomite.com/resources/coa.pdf )〕
