Just as in the atmosphere, the moving and interacting of gas masses results in various climatatic and meteorological phenomena,there are also in oceans many sea-water masses. Whose movement and interaction results in various oceanic phenomena. Mixing occuring on the oceanic frontal zones between water masses can lead to syngenetic sedimentary enrichment of ore-building materials. This is a new mechanism of ore-building for sedimentary deposits and for source beds in sedimentary rocks. It occurs very often on the earth surface through the geological time, but is not yet well known.
