A mineral deposit in the form of a network of veinlets diffused in the country rock.



an ore body formed by a mass of rock permeated by a dense network of variously oriented veins and vein-lets containing the ore minerals; such minerals in the form of phenocrysts are usually found in rocks interpenetrated by veinlets.

A distinction is made between areal and linear stockworks. Areal stockworks are cube-shaped with sinuous boundaries. Linear stockworks extend in one direction. The dimensions of stock-works range from a few dozen meters to several kilometers. Stockworks are classified with the group of hydrothermal formations that arise upon the deposition of the metal-bearing substance from hot mineralized solutions circulating in fissured rock. Some deposits of copper, molybdenum, tungsten, gold, tin, beryllium, uranium, mercury, and other metal ores belong to this group.
