Serpentine thin section

Relief: Low-Moderate positive Habit/Form: Fibrous serpentine is typically chrysotile and it commonly forms veins with fibers across the width or matted masses. Lizardite is commonly very fine-grained and may form an irregular net-like pattern with uneven or undulatory extinction. Antigorite is often more or less micaceous and may form foliated or scaly masses.
