Sedimentologic, diagenetic and tectonostratigraphic study of upper Mississippian, near-coast continental and shallow marine units in successor basins of the Appalachian belt

即将提出的建议将是前一项建议的后续行动，前一项建议专门研究位于加拿大东南部海洋温莎群边缘的密西西比河上游大陆碎屑岩和潜水钙质岩。该研究还涉及这些岩石在宾夕法尼亚时代的后续变形（Jutras等人，115：1538-1551; Jutras等人，2003 b，Atl.地质学39：201-211）。最近在加拿大加斯佩西东部发现了一个由宾夕法尼亚断层角砾岩控制的油藏（Galt#3井，目前由JUNEX和彼得罗利亚开采）要求更加重视加拿大东南部密西西比晚期盆地的沉积后变形，尽管正在进行的研究的主要重点仍将是沉积学，其边缘海相/陆相碎屑岩单元的地层学和成岩作用。这项研究最终将涉及与欧洲年龄相当的岩石的相关性，以获得阿巴拉契亚/加里东造山带上古生界后继盆地的裂陷前古地理的更大图景。总之，正在进行的研究旨在通过对近岸、大陆和浅海沉积的研究，更好地了解构造对温莎海入侵和古地理演化的控制。它还旨在更好地确定密西西比晚期盆地的结构和边缘海区的地层关系，以促进这些单元的最终石油和天然气勘探。

The upcoming proposal will be a follow-up of the previous, which was dedicated to the study of upper Mississippian continental clastic rocks and phreatic calcretes that are marginal to the marine Windsor Group of southeastern Canada. The study also involved the subsequent deformation of these rocks in Pennsylvanian times (Jutras et al., 2003a, GSA Bull. 115: 1538-1551; Jutras et al., 2003b, Atl. Geol. 39: 201-211). The recent discovery of an oil reservoir hosted by Pennsylvanian fault breccia in eastern Gaspésie, QC (Well Galt #3, presently exploited by JUNEX and Petrolia) calls for greater emphasis to be placed on the post-sedimentary deformation of the late Mississippian basins of southeastern Canada, although the main emphasis of the ongoing study will remain on the sedimentology, stratigraphy and diagenesis of their marginal marine/continental clastic units. The study will eventually involve correlations with age equivalent rocks of Europe in order to obtain a greater picture of the pre-rifting paleogeography of upper Paleozoic successor basins in the Appalachian/Caledonian orogenic belt. In a nutshell, the ongoing research aims at obtaining a better understanding of the tectonic controls on the Windsor Sea invasion and paleogeographic evolution through the study of near coast, continental and shallow marine deposits. It also aims at obtaining a better definition of late Mississippian basin architectures and stratigraphic relationships in marginal marine areas in order to facilitate eventual oil and gas exploration in these units.
