Sedimentary rocks of Larsen basin
Entry ID: dlb_LarsenBasin


Summary
Abstract: This dataset consists of: (1) a suite of sedimentary rocks (primarily sandstones, with subordinate mudstones, conglomerates, glauconites and volcanic ashes) collected from Cretaceous through Paleogene strata of the Larsen basin, Antarctic Peninsula, and (2) geochronology and geochemistry data from some of the aforementioned samples.

The collection and analysis of samples in this growing database ... View entire text

Purpose: These samples and resulting data were collected to assess the provenance of sediment delivered to the Larsen basin during the lead-up to the purported glaciation of Antarctica in the late Eocene and earliest Oligocene, primarily to understand the history of opening of Drake Passage between the Antarctic Peninsula and southernmost South America. Some samples and data were collected to improve the age constraints on the sampled strata. These samples are also being used to understand the Cretaceous depositional and provenance history of the Larsen basin, in part to assess the Cretaceous glaciation hypothesis.

ISO Topic Category
Quality The quality of geochronology and geochemistry data is variable depending largely upon sample quality, but is generally within the standards required for publication in scientific journals in the first decade of the 21st century.
Access Constraints Access to and use of samples is dependent upon the state of ongoing projects at the University of South Carolina. Contact PI (David Barbeau) for any sample usage requests.

Use of acquired and published geochronology and geochemistry data is unconstrained.

Access to and use of unpublished geochronology and geochemistry data is dependent upon the state of ongoing projects at the University of South Carolina. Contact PI (David Barbeau) with any requests or inquiries about existing unpublished data.
Use Constraints Use of acquired and published geochronology and geochemistry data is unconstrained, pending acknowledgement of the Tectonics & Sedimentation Laboratory at the University of South Carolina and citation of peer-reviewed publications in which the data was originally published.

Access to and use of unpublished geochronology and geochemistry data is dependent upon the state of ongoing projects at the University of South Carolina. Contact PI (David Barbeau) with any requests or inquiries about existing unpublished data.
