Petrology of Gravel Size Clasts from Miocene sediments collected at Site U1521 during International Ocean Discovery Programme (IODP) Expedition 374 to the Ross Sea, Antarctica

This dataset comprises continuous logging of clasts >2 mm from International Ocean Discovery Program Expedition 374 Site U1521 to the Ross Sea, collected on the RV JOIDES Resolution. Shipboard biostratigraphy and magnetostratigraphy suggests the sediments are early Miocene in age (McKay et al., 2019, Proceedings of the International Ocean Discovery Program). Logged clasts are grouped by core into seven main lithological groups: igneous rocks, quartz fragments, dolerites, volcanic rocks, metamorphic rocks, sedimentary rocks and sedimentary intraclasts. A full methods description is provided at the bottom of the data file. The clast abundances can be compared to knowledge of terrestrial geology, allowing the changing provenance of the sediments to be traced.

Statement

The gravel fraction (>2 mm) was characterized in continuum along the core, between 648.17 and 209.17 mbsf. Clasts exposed in the cut surface of the archive half core were measured, logged and described on the basis of macroscopic features (e.g. shape, colour, texture). Logging aimed to identify the distribution and variation of the gravel-size clasts along the core length. Clast logging followed the methodologies applied to the ANDRILL and CRP records; on the basis of macroscopic features, clasts were grouped into seven main lithological groups: igneous rocks, quartz fragments, dolerites, volcanic rocks, metamorphic rocks, sedimentary rocks and sedimentary intraclasts (Talarico and Sandroni, 1998; 2009; Talarico et al., 2000; Sandroni and Talarico, 2001). In addition, 73 pebble to cobble-sized clasts were sampled for petrographic analysis, of which the most representative of each lithological group were analysed using standard petrographic methods with polarized light microscopy.
