  • ACTINOLITE (Calcium Magnesium Iron Silicate Hydroxide)

    www.galleries.com/Actinolite Actinolite is a relatively common mineral in some metamorphic rocks. It belongs to a series with the minerals tremolite and ferro-actinolite. A series occurs when ions can freely substitute between each other. In this case, when iron is predominant the mineral is ferro-actinolite and when magnesium is predominant the mineral is tremolite.
