US-Czech Research on Plant Taphonomic Character of Intermontane Carboniferous Floras

INT 9513189 Gastaldo 这个美国-由奥本大学的罗伯特·加斯塔尔多和捷克地质调查局的兹贝内克·西穆内克合作的捷克古植物学研究项目将研究捷克共和国三个山间盆地地质沉积物中代表的波希米亚地块的石炭纪植物。 其目的是比较这些沉积环境的特点与低地沿海植物区系的泥炭沼泽和碎屑基质植物组合中发现的密西西比-宾夕法尼亚州的层型部分的阿巴拉契亚山脉，这是众所周知的美国参与者。 这项比较工作将大量利用捷克地质调查局过去几十年从钻孔中提取的大量植物化石。 目的是在性格背景下解释这些数据集。 这一合作研究的结果应有助于我们了解美国山间盆地石炭纪植物群的埋藏条件。 这一点意义重大，因为大多数欧美地层都受到海平面大范围波动的影响。 相比之下，波希米亚地块的样品提供了山间盆地内连续配置的例子。 在这些盆地的沉积学和植物区系方面的比较了解，预计将产生有价值的新信息的古气候变化和植被的反应，在一个地区跨越纳穆里纪（晚密西西比）到Autunian（晚宾夕法尼亚-早二叠世）。 这将提供一个机会，以评估石炭纪植被的变化，在这一地质间隔在沿海影响以外的设置。 此外，研究结果可能提供有关煤层中硫和灰分的来源以及山间盆地煤层甲烷潜力的实际见解。 这个古植物学和古环境研究项目实现了促进基础科学知识的计划目标，使美国和东欧的领先专家能够联合收割机互补人才，并在共同感兴趣和能力的领域汇集研究资源。 ??

INT 9513189 Gastaldo This U.S.-Czech paleobotanical research project between Robert Gastaldo of Auburn University and Zbynek Simunek of the Czech Geological Survey will examine Carboniferous plants of the Bohemian Massif as represented in geologic deposits of three intermontane basins of the Czech Republic. The intent is to compare the characteristics of these deposition environments with lowland coastal floras of peat swamps and clastic substrate plant assemblages found in the Mississippian-Pennslyvanian stratotype section of the Appalachians which are well known to the U.S. participants. The comparative work will draw heavily upon a large fossil plant collection extracted from boreholes over past decades by the Czech Geological Survey. The intent is to interpret these data sets within dispositional context. Results of this cooperative study should contribute to our knowledge of the taphonomic conditions of Carboniferous floras in the intermontane basins of the United States. This is significant because most Euramerican strata were subjected to wide-scale fluctuations in eustatic sea level. In contrast, samples from the Bohemian Massif offer examples of continuous disposition within intermontane basins. A comparative understanding of the sedimentological and floras aspects in these basins is expected to yield valuable new information on paleoclimate change and vegetational responses during an area spanning the Namurian (Late Mississippian) into the Autunian (Late Pennsylvanian-Early Permian). This will provide an opportunity to assess Carboniferous vegetation change over this geological interval in a setting outside coastal influences. Additionally, results may provide practical insights concerning the origin of sulfur and ash in coal beds as well as coal bed methane potential in intermontane basins, in general. This project in paleobotany and paleoenvironmental research fulfills the program objective of advancing basic scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of mutual interest and competence. ??
