Permo-Triassic unconformities in the Central European Basin: Their petrographic, geochemical and petrophysical fingerprints and tectonic implications

中欧盆地二叠纪-三叠纪不整合面:其岩石学、地球化学和岩石物理指纹及构造意义

基本信息

项目摘要

The Late Permian/Early Triassic succession of the Central European Basin was repeatedly affected by tectonic pulses associated with the earliest phases of Tethyan and Arctic-North Atlantic rifting. Effects of differential tectonic subsidence are particularly well recorded by unconformities which form widespread sequence boundaries. The anatomy, thickness of erosion and the petrographic, geochemical and petrophysical characteristics of such unconformities will be examined by an integrated analysis of available seismic sections, wireline logs and field outcrop data. Sequence stratigraphic concepts are used to establish a high-resolution correlation between time-equivalent sequences from (A) contrasting depositional settings (marine influenced Alpine Triassic vs non-marine fluvial and aeolian of N. Europe) and (B) contrasting tectonic (rift vs "cratonic" basin) settings. The proposed project aims to identify, separate and quantify tectonic controls on sequence development. Priority questions are: How are unconformities expressed in these contrasting depositional and tectonic settings and what is the relevant tectonic input to the provision of accommodation space? Knowledge of the distribution, geometry, and erosional thickness of unconformities provides not only key information on the palaeotectonic setting of the Central European basin but is also of great importance for HC reservoir modelling and seismic section analysis. Published results will evaluate the potential relative importance of tectonism in the development of sequences generally and thus will stand as a baseline study by which to calibrate sequence stratigraphic and hydrocarbon reservoir investigations elsewhere.
中欧盆地的晚二叠世/早三叠世序列反复受到与特提斯和北极-北大西洋裂谷最早阶段相关的构造脉冲的影响。差异构造沉降的影响特别好地记录在形成广泛层序边界的不整合面上。将通过对现有地震剖面、电缆测井和野外露头数据的综合分析,对这种不整合面的解剖学、侵蚀厚度以及岩相学、地球化学和岩石物理特征进行研究。层序地层学概念用于建立时间等效层序之间的高分辨率对比,这些时间等效层序来自(A)对比沉积环境(受海洋影响的阿尔卑斯三叠纪与N.欧洲)和(B)对比构造(裂谷与“白垩纪”盆地)背景。拟议项目旨在识别、分离和量化构造对层序发育的控制。优先问题是:不整合面在这些对比鲜明的沉积和构造环境中是如何表现的?提供可容纳空间的相关构造输入是什么?不整合面的分布、几何形状和侵蚀厚度不仅提供了中欧盆地古构造背景的关键信息,而且对HC储层建模和地震剖面分析也非常重要。已发表的结果将评价构造作用在层序发育中的潜在相对重要性,从而将作为基准研究,用于校准其他地方的层序地层和油气藏调查。
