Top best answers to the question «Where do you find actinolite»

  • Actinolite is commonly found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of metamorphism of magnesium-rich limestones. The old mineral name uralite is at times applied to an alteration product of primary pyroxene by a mixture composed largely of actinolite.
