DESCRIPTIVE GEOLOGY : SLATE ZONE. 131 



a north-east — south-west to a north and south, and then to a north- 

 west — south-east strike ; so that at the fault between them and the 

 Murree beds their foliation strike is parallel to the outcrop of the 

 Murree beds. The above faults are further indicated by the very 

 much broken up and powdered condition of the next rock to the 

 north, namely, the Infra-Trias limestone which rises in bold scarps. 



As we continue up the ridge towards Srikote over this limestone, 

 we find the beds settle down to a north-east — south-west strike, with 

 a north-vrest dip of 40 to 6o°. At the first rise in the ridge, how- 

 ever, there seems to be a small inverted anticlinal, exposing some 

 dark-coloured slates entirely unmetamorphosed. After passing these 

 there is a steady ascending series in the Infra-Trias, as far as the 

 first high point at the south end of the Srikote ridge. The Infra- 

 Trias limestone here is a little abnormal in character. It is some- 

 what thinner bedded than that of Sirban hill which I take as a type. 

 It is full of cherty bands more or less brecciated in places. Near the 

 high point just referred to, and as we reach the upper horizon of these 

 rocks, the cherty bands increase in number and size, and they become 

 more siliceous and more definitely banded and brecciated as the top is 

 reached. A tumbled mass of very rough crags then shew a clastic 

 breccia or agglomerate of this rock, with a few well-rolled pebbles of 

 white quartzite, and with a sandy and calcareous matrix not very 

 prominent. This clastic breccia and pebbly layer seem to indicate 

 an uncomformity, for the next rock above is a coarse slightly cal- 

 careous sandstone which seems to pass down into the conglomerate. 

 The sandstone is variegated in its colours and is not unlike the coal- 

 bearing sandstone of the Dore river. It is about 30 feet thick, and it 

 gradually passes upwards into dark concretionary Nummulitic lime- 

 stone of the ordinary Hazara type, with minute foraminifera running in 

 strings and throngs among and between the concretions. In this 

 section, which shews no signs of faulting above the Infra-Trias, there 

 is neither Trias, Jura, nor Cretaceous represented, and there is also 

 absent the limestone, which, for convenience, I have placed (not 

 without misgivings) with the Nummulitics, namely, the so-called Grey
