本文以层序－盆地－构造为主线，对层序成因动力学中的构造控制进行了研究。结果表明，层序发育的构造控制主要表现为：1）构造控制盆地边界，进而控制层序充填轮廓；2）构造级次控制层序和层序级别；3)构造属性控制盆地性质，进而控制层序成因格架和界面成因类型；4)随着层序规模和界面级别的增大，构造控制的意义和痕迹越明显；5)同沉积断裂活动控制层序的内部构型；6)构造基底活动形式控制着层序容纳空间和结构型式；7)构造演化控制着盆地演化及性质，进而控制着层序充填样式和组合类型。 相似文献

正On the platform of the Deep-time Digital Earth Program(DDE),sedimentary data are essential for achieving its scientific objectives.These data will take stratigraphic units as their core data carrier,for quantitative or qualitative data analysis.The DDE Sedimentary Data Group is responsible for the management of the sedimentary data on the DDE platform and has now developed into a group of nearly 40 disciplinary experts.This groups main tasks are constructing sedimentary knowledge 相似文献

正1 Introduction Sedimentary rocks archive important information for understanding how the earth system operates and how life and environments have evolved through earth history.Properly identifying characteristics of sedimentary rocks,along with the subsequent interpretation of depositional processes and sedimentary environments in a basin or locality,are fundamental to inter-basinal correlation of sedimentary successions as well as to understanding and deconvolving regional and global processes 相似文献

黔北桐梓红花园地区的五峰组是华南地区奥陶系的重要剖面之一,在其以泥质灰岩为特征的五峰组观音桥段下部黑色含炭质钙质页岩和褐色粉砂岩中分别产有较为丰富的双壳类Modiolopsis和腹足类Holopea。产双壳和腹足类的地层中岩性和生物具有差异性,表明观音桥段沉积早期的沉积环境具有多变的特征。横长卵形、较膨凸的Modiolopsis和其两瓣壳相连保存的标本表明为近原地埋藏,为弱水动力、有氧的、较浅水环境的软质基底。丰度较大的低圆锥形Holopea的不规则的壳顶指向指示了具一定水动力的、沙性基底的浅水环境。 相似文献

The surface sediments from the eastern Pacific Ocean are mainly composed of biogenetic fossils, silicate detritus, ferromanganese spherolites and clay fractions. Among them, the clay fractions with grain size less than 2 μm (mainly clay minerals) are mostprevalent, especially in the non-calcareous sediments (the content of calcareous fossils is less than 5%), the clay fraction contents often exceed 70%[1―5]. Because of the influences of Antarctic Bottom Water (AABW), equatorial currents, … 相似文献
