Structural Setting and Petroleum Prospectivity of Margala Hills, Pakistan

Abstract

 Margala Hills are located in the north of Islamabad, the capital of Pakistan. The petroleum prospectivity of the Margala Hills is discussed through investigating its stratigraphy and structures style. Geological observations reveal that the contact between the molasse sediments and calcareous rocks is normal. Structures are although highly tectonised but the regional faults along the Margala Hills could not be confirmed. It is suggested that the prospective targets for petroleum occur in sedimentary sequences of the Margala Hills are probably also buried beneath regional Nathiagali Thrust. It enhances petroleum prospectivity of the area. Thick sediments with reasonable organic richness, reservoir horizons, top seal, and oil seepages are good indicators for existence of hydrocarbon system in the area.
