New Evidence Confirms 'Snowball Earth' Reached Equatorial Regions
Geologists find critical proof in Colorado rocks, supporting the theory of a global ice age 700 million years ago.
- Researchers from CU Boulder have uncovered physical evidence in Colorado's Front Range that supports the Snowball Earth hypothesis.
- The study highlights Tava sandstone formations as proof that glaciers covered the Earth, even at the equator, during the Cryogenian Period.
- Using laser ablation mass spectrometry, scientists dated these formations to between 690 and 660 million years ago.
- The findings suggest that massive ice sheets likely pushed sediments into underlying rocks, forming unique geological features.
- This discovery provides insights into the climatic conditions that preceded the emergence of multicellular life on Earth.
