Opening of the Drake Passage: Does this event correlate to climate change and
Summary The time frame for opening of the Drake Passage, which resulted in the onset of Antarctic climatic cooling and then to the development of ice sheets on the Antarctic Peninsula, is hypothesized to be an early Oligocene event. Rock units from the topmost levels of the La Meseta Formation on Se...
