Data report: summary of XRF scanning on core sections, IODP Expedition 381

Abstract

IODP Expedition 381 was conducted to examine, at high resolution, the tectonic and sedimentary processes of the earliest phase of continental rifting and the role of climate and sea level change in these processes. Three sites were drilled within the Corinth Rift, central Greece: two sites in the main Gulf of Corinth basin (Sites M0078 and M0079) and a third site in the Alkyonides Gulf in the eastern rift (Site M0080). One of the primary aims of the expedition was to generate a high temporal resolution chronostratigraphy for the synrift section, in particular for the last ~1 My. To assist with this aim and also contribute to investigations of the basin paleoenvironment, regional paleoclimate, and sedimentary geochemistry, a series of core sections were analyzed using X-ray fluorescence (XRF) core scanning. The cores were scanned at the Center for Marine Environmental Sciences (MARUM) facility at the University of Bremen (Germany). This phase of scanning focused on the expanded high-resolution section within Hole M0079A. In addition, the shallowest sections of Holes M0078A and M0078B were scanned (Holocene and/or latest Pleistocene). Along with these sections, a series of intervals were also specifically scanned at a higher resolution for (1) investigation of potential tephra layers (in Holes M0078A, M0078B, and M0080A) and (2) investigation of turbidite-homogenite layers that may have links to earthquake triggering (in Holes M0078B, M0079A, and M0080A). The data presented here are available as a shipboard data set.
