Neogene paleoceanography of Western Australia : rivers, winds, ocean currents and latitudinal controls over sedimentation ...
During the Neogene period, between 23 and 2.58 million years ago, dramatic changes in tectonic and climatic patterns affected ocean currents, sea level, and sedimentation on the continents and in the oceans. A global warm period in the early Miocene ended when ice-sheet expansion on the Antarctic co...

| Summary: | During the Neogene period, between 23 and 2.58 million years ago, dramatic changes in tectonic and climatic patterns affected ocean currents, sea level, and sedimentation on the continents and in the oceans. A global warm period in the early Miocene ended when ice-sheet expansion on the Antarctic continent lowered global temperatures in the middle and late Miocene. Global temperatures rebounded during the Pliocene, succeeded by a return to cooling conditions in the Pleistocene. These Neogene climatic events are important because they represent some of the best past analogues to modern and future climate change. The study of Neogene sedimentary archives therefore constitutes a research opportunity to elucidate the effects that warming climates will have on Earth’s oceans and atmosphere. The Australian continent was particularly affected by the Neogene reorganization of climate and tectonics as the northward movement of the Australian plate shifted the continent to warmer sub-tropical climates.
