Determining Biostratigraphy And Correlation Using Color Alteration Index And Lithofacies Of Conodonts In The Edinburg Formation, Central Virginia, Lauren Showalter
Determining Biostratigraphy And Correlation Using Color Alteration Index And Lithofacies Of Conodonts In The Edinburg Formation, Central Virginia, Lauren Showalter
Senior Honors Projects, 2020-current
Conodont species, CAI and lithofacies analysis are used as methods of correlation to determine the relative age, depositional environment, and post depositional burial history of the Edinburg Formation in central Virginia. Samples collected for conodont microfossils yielded faunas of Baltoniodus sp. or Amorphognathus sp., Periodon grandis and Protopanderodus liripipus from a site near Luray and Drepanoistodus suberectus, Plectodina sp., Protopanderodus liripipus, Oistodus sp., Phragmodus undatus, Erismodus radicans and Panderodus gracilis from a site in Harrisonburg. The species supports a Late Ordovician (Late Sandbian age). Conodonts from both sites have a CAI of 4-5, indicating post-depositional heating of …
Using Foraminifera In Stemseas Site 1 To Understand The Recent Paleoceanographic And Paleoclimatic History Of Tanner Basin, California Borderland, Michael Stanley Stone
Using Foraminifera In Stemseas Site 1 To Understand The Recent Paleoceanographic And Paleoclimatic History Of Tanner Basin, California Borderland, Michael Stanley Stone
Senior Honors Projects, 2010-2019
In May of 2016, the STEMSEAS Educational Transit cruise OC1605-tranA collected the STEMSEAS Site 1 core from the Tanner Basin in the California Borderland. This research serves as the first formal survey of the foraminifera preserved within that core. The purpose of this research is to use foraminifera preserved within that core to understand the recent depositional and paleoenvironmental conditions at Site 1, and to place that information into a regional paleoceanographic and paleoclimatic context. In pursuing this purpose, this research aims to answer three questions: 1) Can biostratigraphic markers in the foraminiferal assemblages in STEMSEAS Site 1 core be …
