Abstract

This dataset contains provenance detrital data from the glacimarine sequence of Deep Sea Drilling Project Leg 28, Site 271 e 272. The two boreholes are located in the middle of the Ross Sea, in a key site close at 180° longitude that is considered the present confluence between ice flows fed by West Antarctica and East Antarctica. These two sites, together, provide insights to Middle Miocene to Present ice sheet dynamics.
We analyzed eight detrital samples of glaciomarine sediments, four from 272 drill core and 4 from 271. We used an integrated single-grain provenance approach (Olivetti et al., 2023). This multi-proxy provenance study employs conventional U-Pb detrital zircon dating integrated with apatite U-Pb and fission-track dating and trace element analysis of detrital apatite.
The dataset suggests a recurrent E - W oscillations of the ice flow divide between ice fed by West and East Antarctica ice sheets, respectively.

          • abstract
            • CharacterString: This dataset contains provenance detrital data from the glacimarine sequence of Deep Sea Drilling Project Leg 28, Site 271 e 272. The two boreholes are located in the middle of the Ross Sea, in a key site close at 180° longitude that is considered the present confluence between ice flows fed by West Antarctica and East Antarctica. These two sites, together, provide insights to Middle Miocene to Present ice sheet dynamics. We analyzed eight detrital samples of glaciomarine sediments, four from 272 drill core and 4 from 271. We used an integrated single-grain provenance approach (Olivetti et al., 2023). This multi-proxy provenance study employs conventional U-Pb detrital zircon dating integrated with apatite U-Pb and fission-track dating and trace element analysis of detrital apatite. The dataset suggests a recurrent E - W oscillations of the ice flow divide between ice fed by West and East Antarctica ice sheets, respectively.
