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

即将到来的提案将是先前提案的后续，该提案致力于研究加拿大东南部海洋温莎群边缘的上密西西比大陆碎屑岩和潜水砾岩。该研究还涉及这些岩石在宾夕法尼亚时期的后续变形（Jutras et al., 2003a，地球物理学报，115:1538-1551;Jutras et al., 2003b, Atl.）。地球科学进展，39(3):391 - 391。最近在QC的gassp<s:1>东部发现了宾夕法尼亚断层角砾岩储集层（Galt #3井，目前由JUNEX和Petrolia开发），尽管目前研究的主要重点仍将放在其边缘海相/陆相碎屑单元的沉积学、地层学和成岩作用上，但仍需要更加重视加拿大东南部晚密西西比盆地的沉积后变形。该研究最终将涉及与欧洲年龄相当的岩石的对比，以获得阿巴拉契亚/加里东造山带上古生界后继盆地裂谷前古地理的更大图景。总而言之，本研究旨在通过对近海岸、大陆和浅海沉积的研究，更好地了解温莎海入侵的构造控制和古地理演化。它还旨在更好地定义密西西比晚期盆地的构造和边缘海相区域的地层关系，以便于最终在这些单元进行油气勘探。

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.
