Researchers have uncovered a dynamic geologic history for Antarctica's Transantarctic Mountains, revealing ancient mountain-building and glaciation events.
A study led by Timothy Paulsen and Jeff Benowitz analyzed mineral grains from igneous rocks, providing insights into the evolution of landscapes hidden beneath the ice sheets. The research highlights a more dynamic Antarctic landscape history than previously recognized.
Key findings include evidence of a glacial period around 300 million years ago. These events likely played a crucial role in shaping the modern landscape and influencing glacial cycles, suggesting a more complex and active past for the region than previously understood.
