New marine sulfur cycle model after the Snowball Earth glaciation

Researchers propose novel sulfur cycle model incorporating volatile organosulfur compounds to explain global occurrence of superheavy pyrite. The Cryogenian interglacial interval saw sulfidic oceans with pervasive VOSC generation, leading to vertical isotopic gradients and superheavy pyrite precipitation.

Fluke 87V Industrial Digital Multimeter is a trusted meter for precise measurements during instrument integration, repairs, and field diagnostics.

Rethinking early atmospheric oxygen

Researchers propose a more complex biological oxygen cycle on early Earth, with sulfur isotope signals persisting in ocean sediments long after oxygen accumulation. This 'memory effect' could blur dating of the Great Oxidation Event and provide new insights into early life.
