*68 KRAFFT: EXOTIC BLOCKS OF MALLA JOHAR. 



part of E. B. 20 also extends for some distance south, where the 

 boundary range turns round towards peak Kungribingri No. 2. The 

 rock is extremely altered and calcspar veins abound in it, but there is 

 an approximately horizontal bedding seen in places. Traces of ammo' 

 nites, resembling Danubites and Flemingites are not uncommon, in 

 spite of the altered state of the rock. From the highest point of block 

 20 (app. 18,500') it may be seen that igneous rocks reach down 

 towards south-east into a valley running in the direction of Chirchun 

 E. G. In this valley exotic blocks also occur. 1 



Unfossiliferous blocks. — We now proceed to consider the un- 

 fossiliferous blocks. 



Sandstone blocks, apparently representing Gieumal sandstone, may 

 be seen almost everywhere, especially near the liassic block No. 16, 

 where they are perfectly denuded out of the igneous rocks and near 

 E. B. 12 (see. pi. 4 and map). 



Grey limestones (dachsteinkalk) occur in one or two places in 

 the vicinity of the liassic blocks. The limestone is decomposed into 

 small debris heaps. 



E. B. 14 is an occurrence of black shales extremely crushed and 

 weathering rusty brown, which looks exactly like certain palaeozoic 

 shales. Ferruginous concretions being common and brown weathering 

 flaggy limestones with plant remains interbedded, there can be no 

 doubt that the occurrence represents sub-division 4b of the upper 

 flysch. 



Two small patches of igneous rocks are seen at a short distance to 

 the north and north-east of the Kiogarh-Chirchun pass. The larger 

 of these includes an accumulation of large blocks, mapped as exotic 

 block 19 (pi. 8). This is one of .the most conspicuous blocks of 

 the area, but unfortunately is devoid even of traces of fossils. The 

 limestone is much altered, massive, of a red and white streaky colour, 



1 One of these exotic blocks is represented on both Mr. Griesbach's and Dr. 

 Diener's maps. In addition to these I have marked two others which 1 noticed 

 from a distance.
