Скачать или смотреть Peridot Exploration: A Geologist's Field Guide to Finding Gemstones

Peridot exploration in ultramafic cumulates focuses on locating gem-quality olivine within fractures and sheared zones, often associated with secondary magmatic or metamorphic fluid injections. These geological settings are typically enriched in minerals like magnesite, clinochrysotile asbestos, and serpentine, which occur as fracture-filled veins. The sheared zones and fluid pathways provide ideal conditions for the crystallization of peridot, particularly in areas where olivine has been preserved or recrystallized during hydrothermal alteration. Understanding the structural geology, mineral associations, and alteration patterns is essential for identifying promising exploration targets, as these features indicate the potential for gemstone-grade peridot formation.
