This is a short review illustrating the fact that Mineral Surface Science and Nanogeoscience are closely associated to the study of mineral nanoparticles, nanominerals and natural nanoporous metal-oxide materials. Typical examples of these natural solid phases include Ti-oxides (e.g., anatase) and peculiar Fe-oxides, as well as fascinating Mn-oxide and Fe-oxide minerals such as todorokite and hematite, occurring in ores and in terrestrial, aquatic and marine environment. All the above solid materials, apart from their involvement in raw materials and mineral resources, show an additional technological and industrial significance.
