| Abstract: | This paper studies the fractional crystallization of basaltic magma by Pearce ratio diagram in Shanwang area, Shandong Province . The result shows that the basanitic magma and the olivine tholeiitic magma in the southern area of Shanwang were derived from the primitive alkalic olivine basaltic magma by the fractional crystallization of 5% ~ 13% and 15% ~ 28% clinopyroxene , respectively .And the alkalic olivine basaltic magma in the north of this area can evolved into basanitic magma by the fractional crystallization of about 18% olivine ,1% ~ 7% clinopyroxene and 7% ~ 13% plagioclase . |
