2014-9-10  Sri Lanka is rich in extensive deposits of dolomitic marbles with large quantities, which have not yet been exploited on an industrial-scale to produce value-added products such as precipitated calcium carbonate (PCC) nanoparticles. PCC is used extensively and is imported by Sri Lankan industries for application as a filler and extender.

Recent dolomites are found in the subtidal, intertidal and supratidal sediments of the lagoons and sabkhas of coastal Al-Khiran, Kuwait. Two stages of diagenetic dolomite formation have been recognised in the sabkhas; one formed during the earlier lagoonal (transgressive) phase and the other during the later sabkha phase after progradation has commenced.
