Short summary
The history of Earth is a story of the co-evolution of minerals and microbes. We present the evidence that moonmilk precipitation is driven by microorganisms within the rocks and not only on the rock surfaces. Moreover, the moonmilk produced within the rocks contributes to rock formation. The calcite speleothem moonmilk is the only known carbonate speleothem on Earth with undoubted biogenic origin, thus representing a biosignature of life.
The history of Earth is a story of the co-evolution of minerals and microbes. We present the...
