Organic matter reported inside Pumapunku andesite
- what the source states
- The authors report organic matter within Pumapunku andesite stone, interpreted as residue of an organo-mineral binder used in casting.
- limitations
- Same team and sample set as GEO-E006 — not independent evidence; treat the pair as one line.
- Volcanic rocks can host organic and glassy phases naturally; discriminating criteria not blind-tested.
