为刻画林子宗群火山岩的喷发强度及演化序列，对典型剖面采用旋回-期次-岩相三级划分的方案。结果表明：林子宗群酸性火山岩岩相序列多以火山通道相开始，爆发相结束，中基性岩多以爆发相与喷溢相交替出现。典中组从底到顶部酸性岩石序列、中性岩石序列及中酸性岩石序列，代表了典中组的三个喷发旋回。年波组从底到顶部火山-沉积序列、沉积序列及中基性岩石序列，代表了年波组的三个旋回。帕那组底部为酸性序列，上部为酸性-沉积序列，代表了帕那组的两个喷发旋回。林子宗群火山活动强度总体表现出由强-弱-强，演化序列具方向性，表现为从酸性→中酸性→中基性→酸性物质的连续喷发。

In order to depict the eruption intensity and evolutionary sequences of Linzizong Group volcanic rocks, this paper adopted three divided methods of volcanic cycle-stage-lithofacies. The results of study show that Linzizong Group volcanic acidic rocks start with volcanic channel phase, and end with the outbreak facies. The intermediate-basic rocks mostly expose as alternating phase of mafic eruption and effusive facies. From bottom to top the Dianzhong group are acidic lithological successions,intermediate lithological successions, and intermediate-acidic rocks. They represent three volicanic cycles of Dianzhong Group. From bottom to top the Nianbo Group are volcanic-sedimentary sequences, sedimentary successions, and intermediate-basic rocks. They represent three volicanic cycles of Nianbo Group. The bottom of Pana group are acidic rocks, and the top are acidic-sedimentary sequences. And they represent the two eruption cycles of Pana group. The intensity of volcanic activity is from strong to weak, then to strong. And the evolution sequence of the rocks is directional, as performing a continuous eruption from acid-intermediate and acidic-intermediate and basic- acid.
