Stratigraphy of the Mississippian Antler Basin: An AnomalousForeland System

密西西比鹿角盆地的地层学:异常的前陆系统

基本信息

项目摘要

The Mississippian Antler basin is a well known but poorly understood sedimentary system. It has been called a foreland, but the geometry and timning of the orogeny that formed the basin have been the subject of diverse speculation. Preliminary work has revealed new stratigraphic detail and several features that are anomalous for a foreland: synorogenic deformation is mild and poorly preserved, deformation took place as several discrete events that caused uplift, the basin was wide and shallow, the foreland was long-lived but the sedimentary section is not thick, and the sedimentary sequences are mostly transgressive. Current foreland basin models are defined by the type of associated orogency, and basin stratigraphy reflects ongoing tectonism. The stratigraphy of the Antler system provides an excellent test of these foreland basin models, because it differs from most foreland systems described to date. This project will emphasize detailed sedimentology of newly recognized stratigraphic sequences, mapping of sedimentary facies, and analysis of synorogenic deformation. The results will be applied to existing models of foreland evolution in order to expand foreland basin models.
密西西比鹿角盆地是一个众所周知但却鲜为人知的沉积体系。它被称为前陆,但形成盆地的造山运动的几何和时间一直是各种猜测的主题。初步工作揭示了新的地层细节和前陆的几个异常特征:同造山变形温和且保存较差,变形是作为几个离散事件而引起的隆升,盆地宽而浅,前陆寿命长但沉积剖面不厚,沉积层序大多为海侵。目前的前陆盆地模式是由伴生造山带类型定义的,盆地地层学反映了持续的构造作用。鹿角体系的地层学为这些前陆盆地模型提供了极好的测试,因为它不同于迄今描述的大多数前陆体系。该项目将着重于新发现的地层层序的详细沉积学,沉积相的绘制,以及同造山变形的分析。这一结果将应用于现有的前陆演化模型,以扩展前陆盆地模型。
