Introduction. Heavy mineral (HM) deposits associated with sediments in basins and paleovalleys are known in many places around the world. HM sands have two main deposit styles: (paleo-)shoreline/marine placers commonly associated with beach (including barrier and aeolian coastal dune) or shallow offshore deposits, and …

Enhancement of the aeromagnetic data, to emphasise linear features striking parallel to …
Mineral Exploration Ore Minerals and Precious Stones. Mineral exploration and mining involve the processes of searching and mining for the two kinds of mineral deposits, the metallic and nonmetallic ore deposits, as well as the precious stones. This is achieved by undertaking regional and detailed mineral exploration programs.
