140 WYNNE : TRANS-INDUS SALT REGION, KOITAT DISTRICT. 



The inversion and crushing- along the north side of the anticlinal 

 Inversion and crush- would seem to have been accompanied by fracture 

 ing * in some places, though probably of no great 



amount, for a highly coloured red band in the tertiary clay and sand- 

 stones occupies the flanks of the hills, outside of which comes a greenish 

 and gray band, chiefly of sandstones, not unlike those of Dungote on 

 Greenish lower tertiary the Indus (eastward of Kalabagh), and these beds 

 seem to be the same as those succeeding the lime- 

 stone where the positions are more natural. In one place at about 300 

 yards outwards from the limestone a thin band of conglomerate occurs 

 in the green sandstone, containing both quartzite and tertiary sand- 

 stone pebbles, a local feature which has been previously noted in the 

 lower beds of the series. 



One of the salt localities of the district occurs in the gypseous 

 series of these hills just on its north side, and on

streams. The exposure of salt, said to be small, lay concealed by fallen 



masses of the gypsum, but a strong white incrustation of the mineral
