    However, the size of iron oxide precipitate particles is limited by the sandstone pore size, which is typically smaller than tens of microns 17,18. Note that a typical particle size of iron oxide in Navajo Sandstone is ~10 mcrometers 3. Thus, iron oxide precipitates confined in these pores remain effective almost forever for Ostwald ripening.
