Witryna23 kwi 2024 · A vein may be defined as an aggregation of mineral matter, more or less tabular or lenticular in form, which was deposited from solution and is of later origin than the inclosing rock. This definition differs from the one found in many textbooks in that no assumption is made as to the origin of the space occupied by the vein or the manner … Veins are common features in rocks and are evidence of fluid flow in fracture systems. Veins provide information on stress, strain, pressure, temperature, fluid origin and fluid composition during their formation. Typical examples include gold lodes, as well as skarn mineralisation.
