mineralogy
Quick Summary
The tremolite-actinolite series consists of amphibole minerals that are silicates of calcium, magnesium, and iron. These minerals are commonly found in regionally metamorphosed rocks like schists. Tremolite is a white or gray mineral, while actinolite is a green variety.12
The minerals in this series can alter into talc, chlorite, or carbonates. The magnesium-rich members of the series, when found in fibrous forms, are known as asbestos. These asbestos varieties have fine, silky fibers with considerable tensile strength.1
