Direct U-Pb dating of titanite in the tubular structures demonstrates an Archean age. These tubular microstructures are identical to microbial ichnofossils in modern basalts, ophiolites, and greenstone belts, and are interpreted as a biogenic signature in these ancient rocks. Microbial colonization of basaltic glass thus appears to have been part of a deep subsurface biosphere established early in Earth's history.
