This report is based upon field investigations covering an area of about 1,400 square miles (3,626 sq km) in the Hindu Kush Mountains of Chitral State in Northern Pakistan and also includes a discussion of geological questions relating to an area of about 8,000 square miles (20,720sq km) in the Chitral-Gilgit Area. The area is extremely rugged; local relief is more than 8,000 feet (2,438 meters) over most of the area and commonly reaches 10,000 feet (3,048 meters). Many peaks are higher than 17,000 feet (5,182 meters), and tirich mir, 8 miles(12,9km) north of the mapped area, is 25,263 feet (7,700 meters) high. The mapped area includes the following units: Devonian Unit; Sarikol Shale (Devonian tocarboniferous); a broad belt of metamorphic rocks of Devonian to Jurassic age; reshun formation, a volcanic Greenstone Unit, a limestone and Phyllite Unit, a Greenschist Unit, and the Chitral Slate-All of Cretaceous Age. Elongate bodies of granite (Cretaceous) underlie large parts of the area. Of stratigraphic interest are (1) the lateral facies change of the reshun formation from fossiliferous conglomeratic red shale and phyllite at reshun, to marble in the Kafiristan area, and (2) the determination of a Cretaceous age for the Chitral Slate, which formerly was considered to be of Paleozoic Age. Structurally, the mapped area is characterized by a system of folds over turned toward the east and south. This fold pattern marks the regional trend of the Hindu Kush Range, from north in the southwestern part of the area to east-northeast in the eastern part. Several reverse and thrust faults separate belts of rocks of Cretaceous age from belts of older rocks. Metallic deposits in the area include (1) veins containing antinomy, lead, and copper with associated gold, silver, and tin; (2) copper localities in mafic rocks and greenschist; and (3) miscellaneous showings, mainly of copper. Antimony has been mined on a small scale at krinj since 1939. The places of mineral potential are the vein-type deposits along the fault zones in the Awireth Gol-Shoghot-Madashil area, the Krinj Mine area, and in the Shishi Valley area. Along these faults the largest showings of copper, lead, and antimony are found, and in the awireth gol locality the lead ore contains large amounts of gold and silver. Nonmetallic mineral deposits include limestone, marble, dolomite, granite, pegmatite, and talc. No commercial limestone industry exists in the Chitral area. However, limestone and marble are used locally for building stone. Granite is also used locally for building stone. Mica and beryl are mined on a small scale from pegmatites 15 miles (24km) northwest of the mapped area.
