The Mount Pavagadh volcanic suite, Deccan Traps: geochemical stratigraphy and magmatic evolution
The patterns of eruption and dispersal of flood basalt lavas on the surface, or as magmas in
dykes and sills within the crust, determine the volcanological and stratigraphic development
of flood basalt provinces. This is a geochemical and Sr-isotopic study of lavas of varied
compositions that outcrop around Mount Pavagadh (829m), Deccan Traps, an important
outlier north of the main basalt outcrop. Most of the∼ 550-m thick exposed section at
Pavagadh is made up of subalkalic basalts rich in the incompatible elements (particularly …
