about a stratiform deposit when occurring in or as a stratigraphic bedding, but a stratabound deposit when just restricted to a particular part of the stratigraphic column Other times we refer to ore deposits typical of certain places, like Bushveld Type (stratiform) and Alpine Type (podiform) orthomagmatic chromite deposits;

In recent years, stratiform copper deposits have accoun-ted for some 20-25% of the western world's copper production, as well as 80% of its cobalt (the latter mostly from Central Africa) Freeman (1986) estimated the total *Sediment-hosted stratiform copper deposits are confined to well-defined stratigraphic units (ie they are stratabound)
Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractur They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore mineralsIn some occurrences, minerals can be extracted at a profit by mining
