Article Synopsis

* A study focused on a 2-billion-year-old rock in South Africa's Bushveld Igneous Complex used advanced techniques to detect both native and contaminant microbes in drill core samples.
* Researchers identified microbial colonization in clay-filled veins of the rock, revealing that tightly packed clay minerals provide essential energy for microbial survival over geological timescales.

Organic matter in carbonaceous chondrites is distributed in fine-grained matrix. To understand pre- and postaccretion history of organic matter and its association with surrounding minerals, microscopic techniques are mandatory. Infrared (IR) spectroscopy is a useful technique, but the spatial resolution of IR is limited to a few micrometers, due to the diffraction limit.
