TKANS-INDUS HILLS. 275 



At a distance of about nine miles to the westward of Kalabagh, 

 the southern escarpment of the continuation of 

 the Salt Range is intersected in a north and 

 south direction by the fine gorge of the Chichali Pass, at one part 

 of which, where it crosses the nummulitic limestone (called the 

 * Barwdza' or gateway, by the natives), the shallow stream finds 

 its way over a bed of flat sand between vertical rocky walls 250 or 

 300 feet high, and only 14 feet 6 inches apart at the narrowest 

 place. 



In this gorge near its mouth there is a good section exposed, showing 

 extraordinary disturbance, and to a certain extent inversion of the 

 strata (see sketch section. Fig. 55, PI. XXXI). At the entrance, crushed, 

 contorted, and faulted beds of the purplish-grey tertiary sandstones and 

 dark-brownish red clays (Nos. 16 and 17) are seen, and the passage into 

 the glen lies between vertical masses of the nummulitic limestone 

 (No. 14) occupying a space of 150 yards across; parts of this limestone 

 show the most intense crushing and compression within the mass. 

 Black, flaggy, and olive-weathering alum-shales (No. 12), containing 

 limestone-nodules, and nearly vertical, are next met with ; then another 

 mass of nummulitic limestone (No. 11), the strata of which, inclining 

 at a high angle to the north, are faulted against some reddish-purple 

 cretaceous sandstones (No. 9), with carbonaceous patches. These are 

 inverted so as to dip steeply underneath dark-greenish olive sandy 

 clays with Gryphaa and non-canaliculate Belemnites (No. 8), associated 

 with which are some greenish sandstones with Ammonites and Belemnites, 

 apparently underlying and passing into black alum-shales (No. 7) with 

 canaliculate Belemnites. These, by reason of a reversed, crooked, 

 angular, fault, partly underlie thin-bedded Jurassic limestones (No. 5), 

 with Pectens, &c., and these beds are again obliquely faulted and 

 brought beneath more thin-bedded impure Jurassic limestones and 

 dark shales, red clays, and white sandstones (No. 4 ?) containing a 

 few fossils such as Gervillia. Another fault, yet more oblique than 

 the last, nearly coincides with the axis of an inverted anticlinal fold
