The micropaleontology and stratigraphy of the subsurface "Heath" formation (Mississippian-Pennsylvanian) of western North Dakota
<p>The thesis here abstracted was written under the direction of F. D. Holland, Jr., and approved by Wilson M. Laird and Walter L. Moore as members of the examining committee, of which Dr. Holland was chairman.</p> <p>The “Heath” Formation, between the underlying Otter and the overlying Amsden(?) …

Analysis of Two Neighboring Miocene Paleo-Turbidite Systems in a Complex Deep-Water Environment: Implications for Biostratigraphic Techniques Used in Gulf of Mexico Petroleum Exploration Studies
… (2005), (b) determine specific pitfalls of micropaleontology as a tool in this environment, and (c) provide guidelines for the application of biostratigraphic data in the deep-water. Results indicate that the previous depo-history modeling did not account for local complexity, thus lessening …

Cenozoic deep-water agglutinated foraminifera in the North Atlantic
Cenozoic (predominantly Paleogene) "flysch-type" agglutinated foraminiferal assemblages and their modern analogs in the North Atlantic and adjacent areas have been studied to provide an overview of their spatial and temporal distribution and utility for paleoenvironmental analysis. Over 200 species …

Benthic foraminiferal change and depositional history across the Cretaceous – Paleogene (K/Pg) boundary in the Brazos River area, Texas
… stratigraphy package is determined based on the micropaleontology and sedimentology in the Brazos River area. The latest Maastrichtian is marked by a sealevel rise immediately before the K/Pg boundary. Immediately after the K/Pg event, sealevel fell and is recorded as a change from mid to inner …

Late cretaceous (Maestrichtian) calcareous nannoplankton biogeography with emphasis on events immediately preceding the cretaceous/paleocene boundary
The Maestrichtian biogeography of calcareous nannoplankton is investigated in order to characterize paleoenvironmental conditions in the marine photic zone during the latest Cretaceous. Different theories explaining the biospheric turnover at the Cretaceous/Paleocene (KIP) boundary have …

High-resolution stratigraphy of Central and Southern Adriatic Quaternary deposits of sub-Milankovian climate change on Mediterranean circulation
… the project. The final framework based on: micropaleontology (calcareous nannofossils and foraminifers’ bioevents), climatic cyclicity (foraminifers’ assemblages), geochemistry (oxygen stable isotope, made out on planktic and benthic records), paleomagnetism, radiometric ages (14C AMS), …
