WebbOre genesis. High-grade gold ore from the Harvard Mine, Jamestown, California, a wide quartz -gold vein in California's Mother Lode. Specimen is 3.2 cm (1.3 in) wide. Various theories of ore genesis explain how the various types of mineral deposits form within Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined. A pisolite (from Ancient Greek πίσον (píson) 'pea') is a sedimentary rock made of pisoids, which are concretionary grains – typically of calcium carbonate which resemble ooids, but are more than 2 mm in diameter. These grains are approximately spherical and have concentric layers reaching 10 … Visa mer • Ooid • Oolite Visa mer • Manutchehr-Danai, Mohsen (2009). Dictionary of gems and gemology (3rd ed.).
