Polarized light photomicrograph of a thin section of serpentinized peridotite from Alpe Arami, Switzerland. Peridotite, mainly made of the mineral olivine, is the main constituent of the Earth's mantle. When peridotite interacts with water, its mineral content is easily altered, forming another hydrous silicate called serpentine. The diagonal blue veinlet seen here is composed of serpentine and some black magnetite; the veinlet is surrounded by olivine. Polarized light, crossed polarizers and red tint lambda plate. The rock slice (thin section) is 30-micron-thick. Zeiss Axioscop 40pol. Width of view: 2.7 mm. | |
