Petrography, mineralogy, and geochemistry of deep gravelly sands in the Eyreville B core, Chesapeake Bay impact structure

Funding

The drilling at Eyreville Farm was supported by ICDP, USGS, and NASA. We appreciate the work of general contractor DOSECC and drilling operator Major Drilling, USA. This work was supported by the Austrian Science Fund (FWF), project P18862-N10 (to C. K.). The help of the staff at the USGS National Center, Reston, during the sampling process is appreciated. We appreciate the help of E. Klapfer and J. Sterba (Institute of Atomic and Subatomic Physics, Vienna) with the irradiations. We thank R.- T. Schmitt, K. Krahn and H. R. Knofler (Museum of Natural History, Humboldt-University, Berlin, Germany) and P. Nagl and P. McDonald (University of Vienna) for the XRF analysis. The assistance of E. Libowitzky (University of Vienna) with the microRaman spectroscopy and of F. Brandstaetter (Natural History Museum, Vienna) with the SEM EDX analyses is highly appreciated. We thank F. Ottner (University of Natural Resources and Applied Life Sciences, Vienna) for performing simultaneous thermal analysis. W. U. Reimold (Museum of Natural History, Humboldt-University, Berlin, Germany) is thanked for providing thin sections of the gravelly sand samples from the Berlin sample suite. We thank C. W. Poag and an anonymous referee, as well as the internal USGS referees G. S. Gohn and L. E. Edwards, for constructive comments that helped to substantially improve the manuscript.
