...Lucie Ringuette; Jacques Martignole; Brian F. Windley Abstract The Jijal ultramafic-mafic sequence is the lowermost exposed part of the Kohistan terrane. Petrography and geothermobarometry show that garnet-bearing assemblages of the Jijal sequence consist of a mosaic of magmatic and metamorphic...

.... The work of Jan (in Tahirkheli & Jan 1979) over many years in the Swat Valley produced much petrological data on the Kohistan sequence. The Jijal Complex is a 200 km' tectonic wedge of high pressure granulites and ultramafic rocks exposed on the Karakorum High- way against the MMT (Jan & Howie 1981). Rb-Sr...

... Arc Complex (KAC) of Pakistan is a rare window into a nearly complete section of lower arc crust, revealing a sequence of igneous rocks representing discrete batches of magma underplated along the base of the arc crust. We present high-precision isotope dilution–thermal ionization mass spectrometry U...

...HIROSHI YAMAMOTO; EIZO NAKAMURA Abstract Sm–Nd mineral-isochron ages of garnet granulites in the southern part of the Kohistan complex are determined. The 91.0 ± 6.3 Ma age is obtained from a granulite body of the Jijal complex at Pattan and the 69.5 ± 9.3 Ma age is obtained from a granulite body...

...HIROSHI YAMAMOTO Abstract In the Swat-Indus Kohistan area, lower crustal rocks of the Kohistan arc including amphibolites, granulites and ultramafic rocks are widely exposed. Detailed petrological-structural studies reveal that the Chilas-Jijal metamorphic complex comprises essentially intermediate...

...; and were the jadeitites of the Jade Mines belt originally part of the Tagaung–Myitkyina belt? We compare the proposed protoliths of the Burmese jadeitites with similar, but unjadeititized, rocks from the Oman ophiolite mantle sequence and from the Jijal Complex, a sequence of ultramafic rocks (Sapat...

.... The general features of the geology of the arc can be found in Tahirkeli (1979, 1982), Tahirkeli & Jan (1979), Coward et al. (1982, 1986, 1987) and are briefly summarized below. From south to north the Kohistan sequence is made up of the following rock groups (see Fig. 1). Jijal complex Close to the MMT...

... arc and the Asian plate. The shear zone would have sliced across the lower part of the arc, obducting it over amphibolites and Jijal complex, thickening the arc sequence and causing the high grade metamorphic assemblages in the footwall to the shear. The local northerly directed thrusts along...

... rocks. In the southmost part of the Kohistan arc, the Jijal Complex represents the upper mantle to lower crust transition overlain by a thick sequence of metaplutonic and minor metavolcanic and metasedimentary rocks referred to as the Southern Amphibolites (Kamila Complex). The Chilas Complex resulted...

A plot of X Cr vs. X Mg shows that the samples are similar to those of arc cumulates ( Kepezhinskas et al., 1993 ; Arai, 1992 ), including those from southeast Alaskan complex ( Bird and Clark, 1976 ) and the Jijal complex in Pakistan ( Niida...

... are more clearly defined, permitting the construction of a revised magmatic-tectonic history for the arc. The oldest units are transitional oceanic-type basalts, which form the basement to the subduction related sequence. Arc-type gabbroic sheets and plutons intrude the oceanic basalts: together these form...
