Ore Mineralization on the Ocean Floor in the Central Atlantic in the Context of the Features of Its Geological Structure

摘要

In the multidisciplinary research on the geology and mineral resources of the ocean floor, special attention is paid to the geodynamical and metallogenetic studies of mid-ocean ridges. This is caused by the fact that, over the past two decades, large deposits of massive sulfide polymetalic ores were discovered in the axial parts of these ridges. Their formation is related to the so-called "black smokers." this phenomenon is represented by a powerful jet of a high-temperature fluid (300-400 deg C) welling out of the ocean floor; it contains a suspension of finely dispersed ore minerals (sulfides). A mound composed of virtually pure ore is formed around this kind of jet.
