| 摘 要： | 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，火山活动具有喷发相（喷溢亚相）－喷发－沉积相的特点，构成了具多韵性的火山喷发特征，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。

| Abstract: | 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. |
