Common geological features of the known kimberlite-occurring regions in the continents are briefly described with special notice to certain tectonic processes that seem to be linked to the eruption of kimberlites.Some investigators suppose that kimberlite magma originated in the peridotite layer just below the Mohorovicic discontinuity. Judging, however, from the tectonic processes prior to the eruption of kimberlites in most regions and the structural model concerning to the crust and the upper mantle supported by the writer, sources of kimberlites might be in more deeper part of the mantle than the peridotite layer.
