The Antarctic Plate started to subduct beneath South America 14 million years ago in the Miocene, forming the Chile Triple Junction. At first the Antarctic Plate subducted only in the southernmost tip of Patagonia, meaning that the Chile Triple Junction lay near the Strait of Magellan.
Miocen (z gr. μείων ‘mniej’ i καινός ‘nowy’) – najstarsza epoka neogenu. Czas przemian geologicznych skorupy ziemskiej. Wypiętrzenie nowych łańcuchów górskich zmieniło cyrkulację powietrza i wód.

25 paź 2024 · Learn about the Miocene Epoch, the earliest major division of the Neogene Period, from 23 to 5.3 million years ago. Explore the evolution of land and marine life, especially mammals, primates, and whales, during this period.
The Miocene is the first geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago (Ma). The Miocene was named by Sir Charles Lyell.
The Miocene Epoch, 23.03 to 5.3 million years ago,* was a time of warmer global climates than those in the preceeding Oligocene or the following Pliocene and it's notable in that two major ecosystems made their first appearances: kelp forests and grasslands.
23 gru 2020 · The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and fauna evolved into the same taxa that exist today.
The Miocene is a geologic time period lasting over 17 million years, characterized by the transition from a greenhouse to an icehouse world. It was marked by global cooling, tectonic activities, stabilization of Antarctic ice sheets, development of Northern Hemisphere ice sheets, intensification of monsoon systems, and expansion of grasslands.
