166 KRAFFT: EXOTIC BLOCKS OF MALLA JOHAR. 



2. — The Exotic blocks. 



South of the Kiogarh high plateau igneous rocks occur in three 

 patches. The largest of these is very complicated in outline, owing to 

 the disturbances it has undergone. It is remarkable for its very 

 interesting blocks. Of these E Bs. g, 13, 15 to 18 and 20 yielded 

 fossils, pointing to permo-carboniferous (9, 13, 15, 18), lower liassic 

 (16,17) and lower triassic age (20). Other horizons represented are: 

 Gieumal sandstone, dachsteinkalk and upper flysch, sub-division 4b 

 (14 on map). We will first consider the — 



Permo-carboniferous blocks. — E. B. 9 is the largest of that age 

 found in Malla Johar. It is comparatively little altered,, no doubt in 

 consequence of its size. As recorded above, rare permo-carboniferous 

 brachiopoda are found in it. A few fossils of this age were also found 

 in blocks 13, 15 and 18. A permo-carboniferous age can safely be 

 inferred with respect to blocks 11 and 12, as large crinoid stems 

 abound in them. Block 10 and several others (left out on map) are 

 of doubtful age. What has been mapped as E. B. 18, is a large 

 number of blocks of red and white limestones (pi. 9). They yielded 

 a few permo-carboniferous species. 



Lower Liassic blocks. — In the vicinity of E. B. 18 intensely red, 

 conspicuous patches of debris are seen. In these ammonites of lower 

 liassic age were found. In one place the limestone is in situ (partly 

 to be seen on pi. 9). There it is noticed that the rock is bedded, 

 concretionary, chiefly of red colour but with a few grey layers, thicker 

 than the red beds. It is impossible to say how many liassic blocks 

 were originally present, as they have all been more or less decomposed 

 into large patches of debris. We can distinguish two main occurrences, 

 one (E. B. 17) situated near E. B. 18 and the other, E. B. 16 some- 

 what higher up near the crest of a ridge running from south to north. 



Lower triassic blocks (Fig 4 below). — On the frontier ridge south 

 of the liassic crags an occurrence of red limestones with ammonites
