Description
Summary:碩士 === 國立臺灣大學 === 海洋研究所 === 85 === The basalts from Buon Ma Thuot located in an area dominated by the extrusion tectonics are worthy to study since it is interesting to investigate whether these basalts could have resulted from riht-inducedasthenospheric decompression during stress redistribution associatedwith the cessation of South China Sea basin opening.By compare the chemistry of the alkali and tholeiitic basalts in Buon Ma Thuot area,with REE spestra, spider diagram and the plots of trace element, we findthe usehul information regarding the origin and special significance of these basalts.
