| Summary: | A research work was embarked in the area in order to understand the sedimentary geology, remote sensing,
geomorphology and petrology of the district Sudhunhoti and Poonch, Azad Jammu and Kashmir, Pakistan. For
this purpose the Khirik, Muttail Maira, Thandi Kassi, Kothian, Hill, Maidan, Rhera, Dar, Sairhan, Afsar Market,
Gorah, Nakkar bazaar, Gui Nala, Bandia, Mang, Jassa Pir and Thorar areas were mapped and interpreted on
Digital Elevtion Model (DEM) in the sub-Himalayas of Pakistan. The area has been mutilated by folding and
faulting governed by orogenic forces. The clastic rocks exposed in the area are sandstone, siltstone, claystone
and conglomerates. The sedimentary structures include planner bedding, ripple marks and pebble
imbrications. The rip ups of siltstone and clay occur at the base of sandstone. The sandstone of Nagri Formation
is well exposed in the area. The sandstone contains clasts of volcanics, quartzites, schist and chert. The
sandstone of Dhok Pathan Formation is medium to coarse grained. It contains clasts of gneiss, schists,
quartzites, granite, carbonate and marble. The sandstone is comprised of mineral quartz (23% to 45%), feldspar
(3% to 13%) and the rock fragments of igneous, metamorphic and sedimentary rocks. The accessory minerals
in the Nagri Formation sandstone are biotite (1% to 3%), muscovite (up to 2%), tourmaline (few traces) and
zircon (1%). The cementing material in the rock is calcite (6% to 18%) and silica (2% to 3%). The modal
mineralogical data of the sandstone shows that the sandstone is lithic arenite and lithic graywacke. The modal
data reveal that the detritus was derived from the rising Himalayas in north of the |
