plant can be devised. That the oil occurs north-east of the fault 

 rather points to the conclusion that it has been to some extent 

 prevented from escaping by the protective remains of some sort 

 of anticlinal structure ; the gassiness of some of the seepages may 

 be mostly due to sulphuretted hydrogen. It seems quite probable 

 that the plane of the fault is parallel for some way down with the 

 axial plane of the anticline, but the latter is, in any case, too tight 

 to hold oil in any quantity. Hand-dug wells might perhaps pay in 

 places, and the number and liveliness of the seepages should offer 

 some inducement to such experiments. Boring would be a pure 

 speculation. Any tests should, of course, be located north-east 

 of the limestone core, preferably perhaps where this is seen to form, 

 high ground.

Talishan anticline. 



South of Kifri in the neighbourhood of Talishan a low flat anti- 

 cline extends N.AV.— S.E.. exposing zones " c " and " d " only of the 

 Kurd series. The conglomeratic zone " d " is exposed in the north- 

 eastern limb of the fold, but is not very well developed : the dip 

 here is not more than 3° or 4° and to the north-east. In the 

 brown clays of zone " c ' ; beneath, the dip rises to 17° in one place ; 

 the south-western limb is buried beneath alluvium. The fold prob- 

 ably pitches towards Talishan where the Sarchan River breaks 

 through and rises again south-eastwards, but this was not properly 

 determined. 



Jabal Gilabat Anticline. 



No more Tertiary exposures are seen along the road till the bridge 

 at Shaul Kupri is reached ; here a few feet of practically horizontal 

 greenish and brown, banded clay are exposed in the stream and prob- 

 ablv belong to the upper horizons of the Conglomeratic stage,
