The Quartz Page Occurrence

Rocks are sometimes cut by quartz veins at random orientations, with or without crystals. In other cases there is an obvious pattern in the orientations of the veins: for example, when a igneous rock shrinks during cooling, the cracks may develop into a regular system of fissures that might be filled with quartz from percolating hot brines.
