Short summary
We have developed a high-resolution 3-D tomography approach and successfully applied it. We provided in situ evidence and reveal an abundance of mineral nanoparticles, in dense thin layers or nano-aggregates/clusters, instead of crystalline clay-sized minerals on or near OC surfaces. The key working minerals for C stabilization were reactive short-range-order (SRO) mineral nanoparticles and poorly crystalline submicron-sized clay minerals in a Fe oxyhydroxide-poor environment.
