| Alteration processes: | Pyroxenite Intrusive Has Been Sheared And Altered To Multiform Chlorite Schist And Subsequently Ankerized And Silicified. Chlorite Schist Sometimes Resembles Serpentine Schist Due To The Lusterous Green; In Places This Rock Has A Pseudomorphic Texture Much Like Serpentinized Peridotite But The Phenocrysts Instead Of Being Bastite Are Chlorite Embedded In A Fine-Grained Chlorite Matrix. |
