Abstract

The importance of the sandstones of Murree Group is becoming more and more due to the possibilities of occurrence of hydrocarbons. It is evident from the petrographic and geochemical studies that these sandstones are of sublitharenite type. Probably low to medium grade metamorphic, intermediate to acid igneous and preexisting sedimentary rocks were sources for these rocks. A cratonic near-shore depositional environment is suggested for these sediments. The palaeoclimatic conditions were mild as indicated by their mineralogy.

Abstract

A gabbroic pluton of 4 sq km areal extension crops out at Warikwah, Baramulla District, Kashmir Himalaya. The three rock types in the pluton are recognized as norite, gabbro and quartz gabbro which are the products of differentiation under low PH₂O conditions in that order. The parental magma is considered to be of tholeiitic nature and is derived from a deep source as reflected by major and trace element variation. After the emplacement in an orogenic (collisional) tectonic setting, the pluton has undergone low-grade. amphibolite facies metamorphism.

Abstract

The Gulabgarh region of Kashmir Himalaya presents an interesting area in providing the complete geological section from Salkhalas to Tertiaries which are traversed by two tectonic planes viz., the Murree Thrust in the south and the Panjal Thrust in the north. An attempt has been made in this paper to present pragmatic classificatory models of granites after comparing the tectonic groups of the present area with the classic areas elsewhere in the world.
