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前一项提案的后续，前一项提案致力于研究密西西比上部大陆碎屑岩和潜水钙质岩，这些岩石位于加拿大东南部海相温莎群的边缘。这项研究还涉及这些岩石在宾夕法尼亚时代的后续变形(朱特拉斯等人，2003a，GSA Bull)。115：1538-1551；朱特拉斯等人，2003b，Atl.吉奥尔。39：201-211)。最近在昆士兰东部加斯佩西(Galt#3井，目前由Junex和Petrolia开采)发现了一个由宾夕法尼亚断层角砾岩托管的油藏，这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其边缘海/陆碎屑单元的沉积学、地层学和成岩作用。这项研究最终将涉及与欧洲相当于年龄的岩石的对比，以便更好地了解阿巴拉契亚/加里东造山带上古生代后继盆地的裂谷前古地理。简而言之，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的控制和古地理演化。它还旨在更好地界定密西西比晚期盆地结构和边缘海洋地区的地层关系，以便最终在这些单元进行石油和天然气勘探。

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.
