242 VREDENBURG: SKETCH OF BALOCHISTAN DESERT. 



former case the rocks are cretaceous, in the latter they are probably 

 tertiary. The case is analogous to that of the Chapar range and 

 the strata south of it (page 59), and here also the probable explana- 

 tion is a fault or thrust-plane. 



There are a few outcrops of rocks west of the Malik Gatt, the 

 Small hills south-east most westerly ones forming some small hills 



of Chah-i-Sundan, ., . - -,, ,, . _. _ _. 



south-east of Chah-i-Sundan. They consist of 

 strata very similar to those that form the Malik Gatt ; shales and 

 limestones interbedded with sandstones and conglomerates formed of 

 volcanic fragments. The dip here is not in the same direction, 

 however, as near the Malik Gatt; it is io° west of south at low 

 angles from ro° to 15 . 



This is the most westerly hill which can be regarded as the con- 

 tinuation of the more northern of the two ranges which we have 

 followed from the neighbourhood of Nushki. West of this point 

 everything is hidden by recent deposits for a distance of sixty miles 

 when another set of low parallel ranges rises out of the alluvium 

 south-west of the K6h-i-Sultan, this time with a west-north-west 

 strike. It has already been mentioned (page 55) that they may 

 represent the continuation of the Kharan hills, but it is just as 

 probable that they are connected with the range last described. In 

 fact it is quite possible that beneath the recent deposits of the great 

 sandy desert north of the Hamun-i-Mashkhel, the flexures of both 

 ranges become broader and shallower and finally coalesce into one 

 broad folded area south-west of the K6h-i-Sultan. 



Hills of the Baluch- Afghan Boundary. 

 Let us take it for granted that the folded strata do really continue 

 beneath the recent alluvium between these last hillocks of Chih-i- 

 Sundan and the low ridges south-west of the Koh-i-Sultin, in 

 accordance with the above supposition. We would then have an 

 uninterrupted band of folded strata extending from Nushki to the
