RUI: Sedimentology of the Fluvial to Mid-Estuarine Facies of PA-Aged Valley-Fill Deposits

9405123拉尼尔，本科生参与教师研究，在加强这些学生攻读科学高级学位的准备以及为从事科学教育事业做好准备方面，可以发挥关键作用。这项提议要求资金支持本科生研究堪萨斯州东部道格拉斯集团(密苏里-维吉利安)宾夕法尼亚切割山谷充填矿床的河流向河口中段过渡的沉积学。该研究项目包括获取钻芯，以研究这些古河口相转变的沉积学细节。考虑到这些相的特征是细粒、粉质到泥质的岩性，它们几乎没有形成良好的地表暴露。然而，现有的露头已经从沉积学、地层学和古生物学方面进行了非常详细的分析，这将使这些信息能够同样详细地投射到地下。虽然这些研究的重点是区域性的，但对于切割的山谷充填序列的沉积学和层序地层学具有广泛的影响。这项研究非常适合本科生，因为它的目标明确，它的应用具有科学意义，而且它的范围有限。

9405123 Lanier The involvement of undergraduate students in faculty research can play a critical role in enhancing the preparedness of these students to pursue advanced degrees in the sciences as well as preparation for careers in science education. This proposal requests funding to support undergraduate research concerning the sedimentology of the fluvial to mid-estuarine transitions of Pennsylvanian incised valley-fill deposits from the Douglas Group (Missourian-Virgilian) of eastern Kansas. The research project involves the acquisition of drill cores to study the sedimentological details of these paleoestuarine facies transitions. Given the fine-grained, silty-through-muddy lithologies which characterize these facies, they form few good surface exposures. However, the existing outcrops have been analyzed in great detail in terms of their sedimentology, stratigraphy, and paleontology, which will allow for a similarly detailed projection of this information into the subsurface. Although regional in its focus, these studies have broad implications with regard to the sedimentology and sequence stratigraphy of incised valley-fill successions. The research is ideally suited for undergraduates insofar as it well-defined in its goals, scientifically significant in its application, and confined in its scope.
