Types of quartz veins of the Urals and their crystal content
Authors:
Abstract
Three systems of jointing cracks predominate in the rocks of the crystal-bearing strip of the Northern Urals: concordant, intersecting and transverse. Almost all crystal-bearing quartz veins of the Northern Urals are confined to these cracks. Among the quartz veins of the Northern Urals, the first two types are most common. Transverse quartz veins are less common. It should be noted that the division of quartz veins into the listed types is conditional, since they are all of the same age, genetically related and fulfill a system of three interconnected tectonic cracks
