Abstract
Mongolia possesses considerable identified reserves of marine sedimentary-metamorphosed sheeted phosphorites. More than 60 deposits and occurrences were discovered and identified in Mongolia. Most of phosphorus deposits and occurrences are sedimentary, both marine and terrestrial origin. General distribution of phosphorus resources is concentrated into two main localities (Fig. 1), Khubsugul and Zavkhan, both occurring in the metamorphic-sedimentary sequences of Neo-Proterozoic to Cambrian age. Total estimated phosphorite reserve is 2.4 billion tons, but no mining activity is yet started on phosphorite deposits because of geo-ecological matter.
