Cryogenian Glacial Erosion and Tectonics as Agents of Crustal Recycling Zircon preserves evidence of recycling processes that link surface environments to the mantle. Combined δ18O-εHf in zircon fingerprints magmatic sources and tracks how crustal material is reworked ov....

#openaccess collaboration exploring global #Neoproterozoic records of #zircon O- and Hf-isotopes to study the complex interplay of tectonics, climate, and large igneous province processes in shaping Earth's crustal evolution.

Tonian (Geological periods 🌍)

The Tonian is the first geologic period of the Neoproterozoic Era. It lasted from 1000 to 720 Mya. Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry. The Tonian is […]

The Rise of Algae promoted eukaryote predation in the Neoproterozoic benthos The rise of marine algae stimulated microbial predation at the seafloor, rerouting carbon and energy to the earliest animals.

Adding planktonic algae to anoxic marine sediments promotes the anaerobic growth of phagotrophic #eukaryotes. The #Neoproterozoic Rise of Algae may have similarly promoted benthic phagotrophs, directing carbon, energy, and nutrients to early animals. #ProtistsOnSky
