项目摘要
Trace fossils, unlike most other fossils, allow an assessment of how animals interacted with their environment while they were alive. In rocks of shallow-marine origin, they comprise one of the most common biological features, yet are relatively understudied. Nothing is more sensitive to changes in the environment and climate than the animals that inhabit them, and so trace fossils provide an unparalleled opportunity to investigate how their responses have operated and changed through time. Animal behaviours, and their resulting trace fossils, vary in response to changes in salinity, physical energy, sediment size, deposition rate, water turbidity, etc., permitting highly detailed interpretations of the ancient sedimentary and environmental record. Correspondingly, this research proposal outlines seven studies that focus on assessing how animal-sediment relations have operated in ancient delta, shoreface/beach, and estuarine settings (paleoenvironments). These paleoenvironments will be assessed with respect to their responses to sea level change, used to establish systems tracts that are fundamental subdivisions of sequence stratigraphy. These shallow-marine environments commonly respond to a complex interplay of river, wave, storm and tidal processes, and are referred to as mixed-process systems.The studies in this proposal are designed to answer fundamental questions about shallow-marine deposits, how they change along the paleoshoreline (e.g., delta asymmetry, tidally influenced shorefaces), and how they have responded to changing sea level in the past (e.g., accumulation during falling sea level, low sea level, rising sea level, and stable but high sea level). Concomitantly, the studies also provide young scientists the opportunity to acquire much-needed skills in the identification and interpretation of trace fossils and bioturbation (animal-generated) fabrics, and the integration of these data with physical (process-response) sedimentology. Together, these avenues of research yield more accurate interpretations of the origins of ancient sedimentary deposits, enable the spatial mapping of resulting deposits, and provide criteria for recognizing how ancient marginal-marine environments vary along the shoreline and seaward into the basin. The biological and physical characteristics of the these sedimentary successions have a major impact on the distribution and quality of hydrocarbon reservoirs and aquifers.
与大多数其他化石不同,痕迹化石可以评估动物活着时如何与环境相互作用。在浅海成因的岩石中,它们构成了最常见的生物特征之一,但研究相对较少。没有什么比栖息在环境和气候中的动物对环境和气候的变化更敏感,因此痕迹化石提供了一个无与伦比的机会来研究它们的反应是如何随着时间的推移而运作和变化的。动物的行为以及由此产生的遗迹化石随着盐度、物理能量、沉积物大小、沉积速率、水的浑浊度等的变化而变化,从而允许对古代沉积和环境记录进行非常详细的解释。相应地,这项研究建议概述了七项研究,这些研究侧重于评估动物-沉积物关系在古代三角洲、滨海/海滩和河口环境(古环境)中的作用。这些古环境将根据它们对海平面变化的反应进行评估,用于建立体系域,这些体系域是层序地层学的基本细分。这些浅海环境通常对河流、波浪、风暴和潮汐过程的复杂相互作用作出响应,并被称为混合过程系统。本方案中的研究旨在回答关于浅海沉积的基本问题,它们如何沿古海岸线变化(例如,三角洲不对称,受潮汐影响的海岸),以及它们如何响应过去海平面的变化(例如,在海平面下降、低海平面、海平面上升和稳定但高海平面期间的堆积)。与此同时,这些研究还为年轻科学家提供了在鉴定和解释痕迹化石和生物扰动(动物产生的)组构以及将这些数据与物理(过程-响应)沉积学相结合方面亟需的技能的机会。总之,这些研究途径对古代沉积矿床的起源作出了更准确的解释,使由此产生的矿床的空间制图成为可能,并为认识古代边缘海洋环境如何沿海岸线和向海面进入盆地提供了标准。这些沉积序列的生物和物理特征对油气藏和含水层的分布和质量有重要影响。
