| 英文摘要: |
| On field geology, petrography, mineralogy, fluid inclusion, the bulk composition and geochemistry including REE, trace elements and stable isotopes, the author expounds that quartz-carbonatite, the result of the highly evolved magma, is geneticaly related to kimberlite. Kimberlite contains much volatiles, CO2 and H2 O. According to the theory of melt structure (polymerization model), the roles of CO2 and H2 O in kimberlite are analysed in this paper. With the melt evolution,the high concentration of volatiles and more and more obvious structure roles of CO2 and H2 O,quartz-carbonatite appears, which represents the end of kimberlite magmatism. So the quartz-carbonatite can ba used as a guidence to hiden kimberlite. |
