“…We recognized a number of the rock units and named formations mapped by Calkins et al (1981), Pudsey et al (1985), and Pudsey (1986). In addition, we discovered a new mineralized zone (,20 km 2 ) using the ASTER imagery ( figure 13).…”

Several image-processing techniques were used to map the Chitral area, northern Pakistan. In this area, the world's three greatest mountain ranges, the Himalayas, the Karakoram, and the Hindukush blocks, merge together. The area is extremely rugged; local relief is more than 2500 m. Many peaks are higher than 5000 m and Tirch Mir, 12 km north of the mapped area, is 7702 m. ASTER imagery and a digital elevation model developed from the ASTER data are used for decorrelation stretches, principal components analyses, and spectral angle mapper (SAM) classifications. These image-processing techniques were used to characterize the lithology and structure of the area. This study produced the most current geologic map for fully understanding the interaction between the Kohistan, western Karakoram, and eastern Hindukush blocks along the Shyok Suture and the Tirch Mir Fault. We utilized previously published geologic maps and fieldwork of the area to validate the image classifications. We have discovered two new strike-slip faults, and recent earthquake activity along the faults indicates that the faults are active. Recognition of these faults has potential tectonic significance, as they may be associated with the Chaman Fault -a major transcurrent fault linking the Indian plate with Pamir. Furthermore, we have discovered an anomalous mineralized zone and further work may uncover new mineral deposits.

“…Stauffer (1975) described Devonian in the central part of Chitral, with the Charun quartzite, Koragh dolomite and Shogram quartzite, and laterally Chitral slate. Calkins et al (1981) also gave a description of some Devonian rocks in western Chitral, with rugose corals indicating Middle to late Devonian age.…”

New U-(Th)/Pb geochronology and geochemical analyses of plutonic bodies in the Hindu Kush range, NW Pakistan, provide insight on the crustal growth and tectonic evolution of the southern Eurasian margin. These new data outline a protracted magmatic history that spans the Cambrian to the Neogene (ca. 538 to 23 Ma) and record a variety of petrogenetic associations variably influenced by within plate, volcanic arc, and collision tectonic environments. The Kafiristan pluton (538 ± 4 to 487 ± 3 Ma) yields geochemical signatures consistent with extensional plutonism and rifting of the Hindu Kush terrane from Gondwana. The Tirich Mir (127 ± 1 to 123 ± 1 Ma) and Buni-Zom (110 ± 1 to 104 ± 1 Ma) plutons have geochemical signatures that can be attributed to a subduction related continental volcanic arc system that developed along the southern margin of Eurasia in the Mesozoic. The Garam Chasma pluton, the youngest body in the study area (27.3 ± 0.5 to 22.8 ± 0.4 Ma), yields a geochemical signature consistent with widespread anatexis during crustal thickening related to the development of the Himalaya. The present geochemical and geochronological analysis from the Hindu Kush have produced important new constraints on the timing of tectonic events and variable tectonic settings along the south Eurasian margin before and after the continued India-Asia collision.
