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.

组成这些钾质碱性岩带的岩石：在岩相上，包括深成相、浅成相和喷溢相等不同岩相；在岩性上，从超基性、基性、中性到酸性岩石；造岩矿物，从超基性到酸性岩石中均有透辉石，在基性、超基性岩中有霞石；在岩石化学成分上，所有岩石均表现出富碱高钾富钙，微量元素富集Rb、Sr、Ba等大离子亲石元素和Th、U等放射性元素，贫Nb、Ta、Zr、Hf等高场强元素；稀土元素富集轻稀土，铕负异常不明显；Sr、Nd、Pb同位素组成，显示了物质来源于富集地幔源区。
