Ashlar facing stone is one of resources, whose exploitation volume is increasing day by day. To date, there is a little of experience in the exploration of deposit of ashlar facing stone in Việt Nam. Basing on the collection and analysis of the geological, exploration practice and mining documents in several years, the authors have proposed a classification on the geological groups of the deposits, the type of the exploration works and its density grid with the hope to participate in enhancing the quality of exploration on deposits of ashlar facing stone.
