Southern Exposure: New Paleoclimate Insights From Southern Ocean and Antarctic Margin Sediments
Southern Ocean Antarctic Margin Sediments
2015/7/15
Much of what is known about the evolution of Antarctica's cryosphere in the geologic past is derived from ice-distal deep-sea sedimentary records. Recent advances in drilling technology and climate pr...
Re–Os isotope geochemistry in the surface layers of ferromanganese crusts from the Takuyo Daigo Seamount, northwestern Pacific Ocean
ferromanganese crust Re and Os isotopes geochemistry Takuyo Daigo Seamount northwestern Pacific Ocean
2017/4/10
Os isotope compositions in ferromanganese crusts (Fe–Mn crusts) have been used for the dating of model ages from
present to the Late Cretaceous. This dating method assumes that the Fe–Mn crusts prese...
