The characters of geochemistry are rich alkali. And at the same time the content of calcium is high. They are rich in alkali, high in Potassium, enriched in LILE, LREE and Pb, depleted in HFSE and have a small Sr, Nd, Pb isotope range. Their source is probably a kind of even metasomatic mantle. This is consistent with the fact that there is kimberlite containing flogopite in the deep-source enclosure of Cenozoic super-K alkali lava in the southern part of this rock zone.
