Growth faults and the record of tectonic and sedimentary signals in growth strata

重力驱动的生长断层和生长断层沉积序列已在世界许多地区被发现，通常与经济上重要的碳氢化合物资源有关。然而，很少有研究针对这些系统进行详细的构造-沉积分析，因此，有关它们发展的几个问题仍然没有解决。在讨论(1)同沉积断层生长和同构造沉积的主要控制因素的相对重要性和量化这些因素的可能性；(2)控制千米级生长断层沉积中心的开始、活动和放弃的机制，包括解释边界断层在规模、倾角方向和断层运动方面的不同构造发展；以及(3)缺乏井控或露头控制的地球物理地下数据对生长序列岩性的可预测性时，问题尤其出现。本研究通过三种不同的地质分析方法来解决上述问题：1)基于露头的野外工作，2)高分辨率遥感分析，3)对位于不同地理和地质环境中的几个大型生长断层系统进行2D/3D地震解释。对不同方法和环境的结果进行量化和比较分析，将允许将特定环境或方法的观察与系统固有信息分开，揭示生长断层和生长地层学发展背后的基本规律。

Gravity-driven growth faults and growth-faulted sedimentary successions have been identified in many parts of the world, often associated with economically important hydrocarbon ressources. However, few studies have targeted a detailed tectonic-sedimentary analysis of these systems, and therefore several issues concerning their development remain unsolved. Questions particularly arise when discussing (1) the relative importance of the main controlling factors for syn-sedimentary fault growth and syn-tectonic deposition, and the possibility to quantify these; (2) the mechanisms that control the initiation, activity and abandonment of kilometre-scale growth-fault-bound depocentres, including the explanation of the diverse structural development of the bounding faults concerning scale, dip direction, and fault movement; and (3) the predictability of lithological properties of growth successions from geophysical subsurface data lacking well or outcrop control. This study tackles the above issues by applying three different geological analysis approaches, 1) outcrop-based field work, 2) highresolution remote-sensing analysis, and 3) 2D/3D seismic interpretation to several large-scale growthfault systems located in different geographic and geological settings. The quantification and comparative analysis of the results from the different approaches and settings will allow to separate setting- or approach-specific observations from system-immanent information, exposing fundamental rules behind the development of growth faults and growth stratigraphy.
