The mineral composition of the rocks was estimated using modal analysis in accordance with procedure suggested by ISRM. It was stated that modal analysis is a valuable tool in the precise determination of the proportion of minerals present in fine to medium grained rocks (gneiss and limestone).

Characterizing the abrasiveness of soil/rock and the allowable wear of hard-facing products in various conditions is a critical factor in selection of the best material for certain applications related to drilling and excavation in mining and construction industries.
