Sequence Stratigraphic Backstripping with Application to the Cenozoic of the North Sea

预计的研究将建立层序地层反剥离程序。层序地层学和成因地层学数据，再加上测井和地壳厚度，将成为沉积物加载的二维、弯曲、反剥离效应的输入。基于各自独特的时间和空间特性，将住宿空间的升降和构造组件分离将成为可能。热沉降随深度呈指数形式，这将是地壳和地幔拉伸的函数。平面内应力对边缘距离有明确的形式，但在时间上没有可预测的形式。尤斯塔西在时间上也没有可预测的形式。然而，尤斯塔西在太空中是不变的。该模型将被设计用于热沉降区域。该模型将在北海盆地北部新生代的大量数据集上进行测试。利用体系域层序地层学和成因层序地层学的概念，对包括走向剖面和倾角剖面在内的5条断层进行了详细解释。最新的生物地层资料、测井资料和深部地震资料也将包括在数据库中。应用层序地层反剥可以得到北海盆地北部一系列可能的拉伸因素、起伏曲线和应力史。显示分解沉积物厚度的横截面以及下面的水深测量将有助于解释沉积物来源和沉积的基底控制。

Kominz 9506572 The projected research will establish a sequence stratigraphic backstripping procedure. Sequence stratigraphic and genetic stratigraphic data coupled with well logs and crustal thicknesses will be the input for a two-dimensional, flexural, backstripping effects of sediment loading. Separation of the eustatic and tectonic components of accommodation space will then be possible, based on the unique temporal and spatial properties of each. Thermally driven subsidence has an exponential form with depth, that will be a function crustal and mantle stretching. In-plane stress has a well-defined form with respect to margin distance, but no predictable form in time. Eustacy also has no predictable form in time. Eustacy, however, is constant in space. The model will be designed to be applied to a thermally subsiding region. The model will be tested on an extensive data set from the Cenozoic of the northern North Sea Basin. Five traverses, including strike and dip sections, will be interpreted in detail, using both systems tract sequence stratigraphic and genetic sequence stratigraphic concepts. Recent biostratigraphic data, well logs and deep seismic data will also be included in the data base. Application of sequence stratigraphic backstripping will produce a range of possible stretching factors, eustatic curves and stress histories for the northern North Sea Basin. Cross sections showing the decompacted sediment thicknesses as well as underlying bathymetry will add insight to interpretations of sediment sources and basement controls on deposition.
