Subsurface habitats on Earth host an extensive extant biosphere and likely provided one of Earth's earliest microbial habitats. Although the site of life's emergence continues to be debated, evidence of early life provides insights into its early evolution and metabolic affinity. Here, we present the discovery of exceptionally well-preserved, ~3.

- * A new plasma ion source, Hyperion-II, significantly improves the spatial resolution and sensitivity of measurements in comparison to older methods, allowing for high-precision analysis of iron isotopes in pyrites.
- * Tests confirm that factors such as crystal orientation and topography have minimal impact on measurement accuracy, leading to a reliable method for analyzing micrometric pyrites with enhanced clarity and stability.
