Ediacaran Acritarch Biostratigraphy in Australia
The Global Stratotype Section and Point for the newly defined Ediacaran System has been ratified at the base of the cap carbonate in Enorama Creek. A near-continuous section from the Marinoan glaciation to the base of the Cambrian is exposed in the Flinders Ranges, with type sections of included stratigraphic units exposed in the area around Brachina and Bunyeroo gorges. The stratigraphy and lo...
متن کاملSediment mixing in the tropical Pacific and radiolarian stratigraphy
[1] The reworking of older radiolarian microfossils into near-surface sediments of the tropical Pacific has long been the source of confusion for the development of radiolarian stratigraphy and of puzzlement over the mechanism(s) that could effect such pervasive reworking. Widespread dissolution “pits” in the sediments of the tropical Pacific are believed to be associated with hydrothermal circ...
متن کاملOverview of Eocene Planktonic Foraminiferal Taxonomy, Paleoecology, Phylogeny, and Biostratigraphy
This monograph has been compiled by members of the Paleogene Planktonic Foraminifera Working Group (hereafter referred to as the Working Group) of the International Subcommission on Paleogene Stratigraphy, International Union of Geological Sciences. It is the second such work in a projected series of three, the first being the Atlas of Paleocene Planktonic Foraminifera published by Smithsonian ...
متن کاملTriassic Lithostratigraphy and Biostratigraphy North of Currie, Elko County, Nevada
The Triassic section north of Currie in southern Elko County, Nevada, is almost 500 m thick and is assigned to the Thaynes Group and overlying Shinarump Formation of the Chinle Group. The Thaynes Group disconformably overlies the Permian Gerster Formation and is mostly calcareous shale with interbedded wackestones that yield marine invertebrate fossils, especially ammonoids. The Shinarump Forma...
متن کاملBiostratigraphy and Paleoenvironmental Analyses of Pleistocene NJ Shelf Sediments
The long-term goal of this project is to understand the patterns and timing of latest Pleistocene sedimentation in the Geoclutter area of the NJ margin. Paleoenvironmental reconstructions of the study area were developed using benthic foraminifera and sediment texture analyses of drill cores obtained in Fall 2002 using the ACHC-800 from the RV Knorr. This award was extended through October 31, ...
