Abstract:

在综合研究南方20多个大型石笋纵剖面的基础上,以董歌洞4号石笋为代表,论述石笋沉积特征与气候演化的对应性.4号石笋从距今147.838±2.6ka开始沉积以来,形成了53个沉积纹(壳)层组,组成24个亚旋回,构成9个旋回,呈现韵律式旋回性沉积特征.石笋纹(壳)层组分、结构、叠复构造呈多级次旋回性很突出,其中沉积间断具普遍性、沉积速率具多变性,间断和速率变化级次亦明显.以系统测试和测年引证沉积特征的同时揭示:①~⑨旋回间沉积间断时间累积达75.804ka,占石笋形成时间的51.21%,①~⑨旋回实际沉积时间仅72.222ka,占形成时间的48.79%;④旋回之前,沉积速率很小,最小仅0.36mm/100a,比最大速率小22~24倍,自⑤旋回起,沉积速率很大,最大达39.03mm/100a,是最小速率的3.8倍.石笋沉积特征与气候环境演化的成生关系表明,石笋沉积多旋回性的纹(壳)层组、亚旋回、旋回与气候演化的气候期、阶段和旋回彼此对应,石笋沉积的多级次旋回及其变化就是气候演化的级次及旋回性转(跃)变时间,彼此同时显示.论证了石笋沉积的多旋回性与气候演化的不稳定性,及其彼此协调的宏观、微观综合表现特征.
