| Dataset abstract | This dataset comprises 40Ar/39Ar dated detrital hornblende grains for 5 samples from IODP Expedition 374 Site U1521 to the Ross Sea, collected on the RV JOIDES Resolution. Shipboard biostratigraphy and magnetostratigraphy suggests the samples are early Miocene in age (McKay et al., 2019, Proceedings of the International Ocean Discovery Program). These data can be compared to terrestrial geochronological data, allowing the changing provenance of the sediments to be traced. |
