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.
