Geology of Part of Warwan Valley, Doda District, Kashmir Himalaya

Systematic geological mapping of an area of about 1000 sq.km.in the Warwan valley by the authors brought out a stratigraphic succession ranging in age from Proterozoic through the Jurassic which is represented in the ascending order by the Proterozoic Salkhala Group and the formations of Palaeozoic Ramsu-Machhal, Lolab, Karihul, Margan, Muth Quartzite, Syringothyris Limestone, Fenestella Shale, Agglomeratic Slate, Panjal Volcanics and Zewan, and Mesozoic Khunamuh, Khrew, Wuyan and Drungam. The Jurassic sequence in the area, designated as the Drumgam Formation, occurs as isolated outliers resting over the upper Triassic rocks with an angular unconformity in Drumgam- Kelnar area. Structurally, the area has experienced polyphase deformation, with atleast three distinct phases of folding, the best example being the Warwan valley Anticline, whose eastern limb is overturned. A pronounced unconformity between the Salkhala (Precambrian) basement and the overlying Palaeozoic-Mesozoic succession occurs in the southern part of the area.
