DESCRIPTIVE GEOLOGY: CRYSTALLINE AND METAMORPHIC ZONE. 235 



sometimes showing foliation or cleavage across the original bedding, 

 are dipping (real dip) about 6o° N.N.E. In the gap to the south 

 of Doodha and between it and another hill further to the south, com- 

 posed of the Infra-Trias limestone, there is an apparent variation of 

 the latter near its junction with the quartz-schists. It becomes 

 brownish, thinner-bedded, and interbedded with shales. There is no 

 trace of any conglomerate. Towards the south in the direction of 

 Jum the same limestone, in inverted synclinal folds many times 

 repeated, seems to outcrop down the slopes and crags west of Beer. 

 The impression obtained by traverses along the southern base of the 

 Doodha hill-mass on the pathway from Kullungur via Jum to Kuch- 

 chee is the same, — an impression, that is to say, that fold after fold of 

 the Infra-Trias follow one another lying in a much-disturbed basin 

 among the schistose quartzites. The lower beds on the southern 

 side are of a darker brownish colour, and there is a thin zone of 

 sandy limestone at the base. Nowhere along this line of country, 

 either to the north of the Infra-Trias outcrop or to the south, is there 

 any occurrence of rocks which might be matched lithologically with 

 the basal beds of the Infra-Trias, neither conglomerate nor sand- 

 stones. Near the Burkot end of the Infra-Trias outcrop in the vici- 

 nity of Pind and Khunda Khoosh the aspect of the whole mass of the 

 Infra«-Trias limestone in its relaticn to the Tanols is as if it lay 

 above the latter, but was at the same time partly interbedded with it. 

 The dip is gentle, at angles of 15 to 20 , shewing the limestone 

 normally overlying Tanols near Hal and being in its lowest layers 

 interbedded with it. Some beds of trap also occur here, apparently 

 dyke rocks. 



Near Hal along the road to Seree-Sher-Shah the same aspect of 

 the rocks is very manifest. The dip gradually veers round from south 

 to south-west, then south again, and finally south-south-west again. 

 The strike thus runs nearly parallel to the Mangal N. The gentle 

 dip of 25 to 30 increases to 40 as the direction changes. Some 

 of the interbedded bands of quartz-schist shew a cleavage foliation 

 distinctly crossing both rocks as in fig. 43.
