项目摘要
Magmas erupting on the earth's surface have experienced various degrees of fractional crystallization, but they keep geochemical information of the source mantle. Tertiary volcanic rocks from various parts of Central and Northeast Japan were studied. A non-peridotite mantle source is suggested from the low-Ni basalt of the Hokuriku Province, degree of melting of the source mantle and its chemical characteristics were determined from the primitive basalt of the northeastern Yamagata Prefecture, and the similarity and difference of the source mantle were discussed by comparing rhyolites from Northeast Japan and continental rift zone.
地球表面喷发的岩浆经历了不同程度的分异结晶作用,但保留了源地幔的地球化学信息。对日本中部和东北部各地的第三纪火山岩进行了研究。推测北陆省的低镍玄武岩为非橄榄岩地幔源区,并根据山形县东北部的原始玄武岩确定了源区地幔的熔融程度及其化学特征,并分析了源区的异同通过比较日本东北部和大陆裂谷带的流纹岩来讨论地幔。
