1) transgressive sequence sets

海侵型层序组合
2) transgressive sequence

海侵层序
3) transgressive-regressive sequence

海侵-海退层序
1.
Two transgressive-regressive sequences can be distinguished in Doushantuo Formation by studying sedimentary structures and succession in the Taoyi.
通过对贵州江口桃映及邻区的坝黄、石竹溪的陡山沱组剖面的沉积序列研究,将陡山沱组划分为2个海侵-海退层序,并根据层序对比认为陡山沱期的生物群均产于陡山沱期第二次海平面开始上升之后形成的沉积中。
4) Succession formation

层序组合

6) Late Quaternary transgressive formation

海侵地层
1.

CAS号:
性质:在红外光谱中通常出现很多的弱吸收,组合模式或组合振动系指对应于两个或多个基本振动频率之和起源,它的弱吸收于多原子分子振动态相互作用的振子的非谐性。与基频振动及倍频所引起的吸收相比,这些吸收是比较弱的。
