This webinar presented by Susobhan Neogi, explores how SIMS technology uncovers secrets buried for 2 billion years.
Discover breakthroughs achieved by the Geological Survey of India (GSI) using the CAMECA Large Geometry SIMS, delivering unmatched precision in sulfur isotope analysis.
Learn how in situ pyrite measurements reveal microbial sulfate reduction in low-sulfate oceans—insights unattainable with conventional methods. By reconstructing Mesoproterozoic ocean chemistry (< ~2 mM sulfate), this research sheds light on Earth’s redox evolution and microbial ecosystems.
Don’t miss this chance to see how SIMS turns geological archives into high-resolution narratives.
⭐ Key learnings will include:
- Unmatched precision with CAMECA IMS 1300 HR3
- δ³⁴S zonation reveals microbial sulfate reduction
- Low-sulfate oceans (< ~2 mM): global impact on biogeochemical cycles
- SIMS delivers insights beyond conventional methods
