Sedimentary rocks of Larsen basin

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 were funded by NSF awards to David Barbeau at the University of South Carolina (IPY/ANT-0732995 on Drake Passage opening; and EAGER/ANT-1241460 on the purported Cretaceous glaciation of Antarctica), and to Sidney Hemming at Lamont-Doherty Earth Observatory of Columbia University (EAGER/ANT-1241574 on the purported Cretaceous glaciation of Antarctica).

A metadata file detailing the samples collected and/or analyzed as part of the collection of this sample and data suite can be found through SESAR at the URL listed in this AMD entry. The associated SESAR metadata file will remain Private until September 2015 to facilitate publication of results. However, any investigators interested in access to, details about, or the status of various samples should contact the PI (David Barbeau, at the Tectonics and Sedimentation Laboratory of the University of South Carolina) in advance of that date if necessary.

Many of the samples & unpublished data in this dataset are being used for a subsequent NSF-funded project, thus access to and use of the samples may be limited through 2015.
