The volcanic activity and rock character of new proterozoic era marine facies in Lushan area

There develops a suit of meta-spilite baschtaunite system volcanic rocks in the south of Lushan Mountain. Lithology combination reflects the regularity of magma evolution from basic to acid. Volcanic activity characterizes extrusive facies-spurt-deposit facies, which constitutes multi-rhythmic volcanic spurting. The progeny of volcanic spurting in Jinningian is studied through isotopic era, which belongs to the morning of new proterozoic era
