Veins in rocks are a result of the precipitation and/or crystallisation of minerals in faults or, more rarely, bedding planes in that rock, usually long after the formation of the rocks in question. This example is of a quartz-vein in a plutonic igneous rock that belongs to an ophiolite series in Wadi Abyad in the Al Hajar Mountains of northeastern Oman | |
