1.2 Myr Band of Earth?Mars Obliquity Modulation on the Evolution of Cold Late Miocene to Warm Early Pliocene Climate

The climatic transitions during the Miocene-Pliocene epochs had significant impacts on worldwide biological diversity and were associated with large turnovers of continental vegetation fauna. Previous studies have shown that late Miocene cooling aridification which was initiated 7 Ma reversed to warm conditions across Boundary ?5.3 Ma. Here, we present detailed orbital pacing Asian monsoon deposits constrain further global climate change this period. We produce high-resolution magnetic susceptibility records reveal 1.2 Myr obliquity modulation would been main driving factor warming occurred ?7 5.3 Ma, respectively.
