Heavy minerals are diagnostic indicators of sandstone provenance, and provide crucial information on sediment transport pathways, sand body distribution and palaeogeography. Heavy mineral stratigraphy is an alternative method of correlation based on the recognition of stratigraphic changes in mineralogy.

Heavy Minerals are diagnostic indicators of sandstone provenance, and provide crucial information on sediment transport pathways, sand body distribution and palaeogeography. Heavy minerals are also useful guides to the extent of burial diagenesis of reservoir sandstones. Stratigraphic changes in heavy mineral assemblages enable the construction of a heavy mineral correlation framework.
