鄂北南化地区寒武纪缓坡沉积及层序

  • 出露于鄂北南化地区的寒武纪地层,总厚约1400m,主体为一套碳酸盐岩。对沉积岩相及相组合的分析表明,本区寒武系主要是形成于碳酸盐缓坡之上,并可以划分出四种主要的沉积相带:浅水陆棚、深水缓坡、浅水缓坡建隆和近岸浅水缓坡。本文还初步研究了区内寒武系露头的层序地层学特征,划分出两个亚层序,并探讨了亚层序内部岩相的不同叠置类型及其在时间上的演化与相应的海平面升降变化。通过与已有的旋回性海平面变化模式相对比,得出了本区寒武纪层序内部的次级旋回可能指示第三级海平面变化旋回的认识。

鄂北南化地区寒武纪缓坡沉积及层序

Abstract: 

出露于鄂北南化地区的寒武纪地层,总厚约1400m,主体为一套碳酸盐岩。对沉积岩相及相组合的分析表明,本区寒武系主要是形成于碳酸盐缓坡之上,并可以划分出四种主要的沉积相带:浅水陆棚、深水缓坡、浅水缓坡建隆和近岸浅水缓坡。本文还初步研究了区内寒武系露头的层序地层学特征,划分出两个亚层序,并探讨了亚层序内部岩相的不同叠置类型及其在时间上的演化与相应的海平面升降变化。通过与已有的旋回性海平面变化模式相对比,得出了本区寒武纪层序内部的次级旋回可能指示第三级海平面变化旋回的认识。
