多期伸展构造作用控制了纽芬兰大浅滩、爱尔兰陆架和北海中央中生代断陷盆地的形成。Jeanne d’Arc盆地、Porcupine盆地和Moray湾盆地构造和地层的一系列响应证明了构造幕之一的晚Cimmerian期同生构造对沉积作用的控制。于沉降速率在大范围出现差异,但断块旋转还不明显的构造作用之后裂谷作用才开始。晚Cimmerian期沉降的“初始挠曲”方式对于晚Oxfordian末期至Kimmeridgian期间局限的缺氧盆地形成及富含有机质的高产层源岩发育都有决定作用。晚Cimmerian裂谷作用的最显著和可识别的构造/岩性地层响应是沉积楔的形成。Jeanned’Arc和Porcupine盆地的Tithonian—上Valanginian阶地层总体上向近于南北走向的断层加厚,表明在广大地区张应力方向为北西西—南东东向。晚Cimmerian期区域张应力方向与局部组构的不一致可能是由于外Moray湾盆地断块的压扭隆升引起。沉积作用对晚Cimmerian裂谷作用的响应是变化着的,尽管一个相同的岩相叠置模式被识别出。在裂谷变形开始时,沉积了不同厚度的砾岩和(或)砂岩,古环境为冲积平原和辫状平原,个别盆地甚至出现水下扇。底部相对较粗的沉积物向上变细,变成富含有机质的页岩和泥灰岩。晚Cim—merian裂谷构造作用末期,古环境和沉积层厚度变化很大,尽管这三个盆地都有水深变浅,氧含量增加和粒度增大的证据。粗—细—粗(储层/源岩/储层)的岩相叠加方式及不整合边界,很大程度上决定于裂谷作用控制的递进沉降。断裂作用初期,裂谷盆地的沉降速率较小,到裂谷中期达到峰值,随后减慢沉降直到伸展作用结束。本文对许多可能解释裂谷诱发的递进沉降作用的地壳反作用机制进行了分析。 The multi-stage extensional tectonics controlled the formation of the Great Forwad in Newfoundland, the Irish shelf, and the central Cenozoic rift basin in the North Sea. A series of responses of tectonics and stratigraphy of the Jeanne d’Arc basin, Porcupine basin and Moray bay basin demonstrate the control of sedimentation by the late Cimmerian synsesis of one of the structural veins. The rifting began only when there was a large range of sedimentation rates, but the tectonism where the fault block rotation was not obvious. Late “Cimmerian” subsidence “initial deflection” is crucial for the development of localized hypoxic basins and organic-rich high-yielding source rocks during the late Oxfordian to Kimmeridgian periods. The most pronounced and identifiable tectonic / lithologic stratigraphic response to late Cimmerian rifting is the formation of sedimentary wedges. The Tithonian-Upper Valanginian stratums of Jeanned’Arc and Porcupine basins are generally thickened to the north-south faults, indicating that the tensile stress direction is in the north-west-south-east-east in the vast area. Late Cimmerian period regional stress direction inconsistencies with local structures may be due to the compression of the Moray Bay basin block caused by compression and uplift. The response of sedimentation to late Cimmerian rifting varies, although a same pattern of facies overlap has been identified. At the beginning of the rift deformation, conglomerates and / or sandstones of different thicknesses were deposited. The paleoenvironment was alluvial plain and braided plains, and even submarine fans appeared in some basins. The relatively thick bottom sediment tapers upward into organic-rich shales and marls. At the end of late Cim-merian rift tectonics, the paleoenvironment and sediment thickness varied greatly, although there was evidence of shallow water depth, increased oxygen content and increased grain size in all three basins. The facies superimposition and unconformity boundary of crude-thin-coarse (reservoir / source rock / reservoir) are largely determined by the progressive subsidence controlled by rifting. At the beginning of the fault, the sedimentation rate in the rift basin was small and peaked in the mid-rift period, then the sedimentation slowed down until the extension was completed. In this paper, many crustal reaction mechanisms that may explain the rift-induced progressive subsidence are analyzed.
