庐山南麓发育一套变细碧-石英角斑岩系火山岩，岩性组合从早到晚反映了由基性到酸性的岩浆演化规律。火山活动具有由喷发相(喷溢亚相)-喷发-沉积相的特点，构成了具多韵律性的火山喷发特征。经同位素年龄研究属晋宁期火山喷发产物，时代归属为新元古代早期。

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. Vocalnic activity characterizes extru-sive facies - spurt - deposit facies, which constitutes multi-rhythmic volcanic spurting. The progeny of vocahic spurting inJinningian is studied through isotopic era, which belonys to the morning of new proterozoic era.
