Eastern China is a Cenozoic composite volcanic rock province,where volcanic rocks of the tholeiiteseries,calc-alkali series,Hy-norm-bearing olivine basalt series,Na-alkali series and K-alkali series coexist.Eastern China is separated into the northern and southern volcanic rock regions by the Changzhou-Yueyangold deep fault.Magma generation and magmatic activities in the northern region were controlled by themantle uplift and old deep faults.These old deep faults were revived and some of them were changed into amultiple rift system due to back-arc expansion.The Bohai Sea depression is situated at the intersection ofthe Lujiang-Tancheng-Shenyang-Mishan and Zhangjiakou-Tianjin uplift belts of the upper mantle.Eogene(71.5—28.5 Ma)tholeiites largely occur in the central part of the mantle uplift;the well developedNeogene (23.8—2.6 Ma)alkali olivine basalts are distributed in the outer lane of the former and theQuaternary(1.48 Ma-recent)peralkali volcanic rocks are far away from them.In the southern region magmageneration and magmatic activities were controlled mainly by plate subduction and three sets of old deepfaults.Studies of incompatible elements and REE show that the degree of enrichment of incompatibleelements and LREE increases with decreasing age,increasing source depth and decreasing degree of partialmelting of the upper mantle.This presumably is an indication of a rapid uplifting and then waning magmatichearth with gradually decreasing temperature,accompanied with down-cutting of the lithospheric faults.We call such a process“a reverse process of magma generation”.And the opposite process of the magmaticevolution of the East African rift in Kenya can be called “a positive process of magma generation”.
