Short summary
Phytoliths contain occluded organic compounds called phytC. The nature and location of phytC in biogenic silica structures is poorly understood. Here, we reconstructed the 3-D structure of phytoliths using 3-D Xray microscopy. We further evidenced a pool of phytC, continuously distributed in the silica structure, using nanoscale secondary ion mass spectrometry (NanoSIMS). Our findings allowed the re-evaluation of previous suggestions regarding phytC quantification and environmental meaning.
