about one mile wide entirely encircle the town. In a southerly 

 direction from Idar these split up into more and more detached 

 rocky hillocks and isolated tors, until they arc finally lost to vu-w 

 altogether at a distance of 3 to 4 miles away. In a northerly 

 direction the Idar group splits up into more widely separated but 

 larger masses, such as the notable one forming the Sabalvada hill, 

 that of Dantroli, Vasna and Asai, and lastly that of J)harol hill. 

 some 10 or 12 miles north of Idar. The members of this extended 

 group of granite hills mostly rise straight out of the Recent alluvial 

 deposits, and form the only hills in the neighbourhood. Their 

 striking and picturesque outlines naturally contrast very much 

 with the continuous and monotonous ridges of Delhi Quartzite 

 seen further to the east and south-east. 



Within a short distance of the Idar-Dharol group there are 

 found to the west, near the banks of the Sabarmati river, one or 

 two isolated granite hills near Mhor, some large and small groupings 

 near Veherabar and Kawa, and from there to the south in the 

 direction of Ora, Umedpura, Desotar, Manpara Chitrori, where 

 the outcrops again become extremely split up into curious little 

 isolated patches and weathered-out gw/sZ-monolithic forms. Across 

 the Sabarmati river, which is here the limit of Idar State, the same 

 granite may be discerned building similar hill features in the Palan- 

 pur State. The Mhor and Veherabar groups are associated with 

 hills of calc-gneiss, vein-quartz, doleritc and other rocks, so that 

 here the country is not so simple as round about Idar. Neverthe- 

 less it is still true that the granite hills keep almost entirely to 

 themselves, rising up from bases entirely surrounded by alluvium, 

 and so absolutely detached from direct contact with any other 

 formation. 



South and south-east of the Idar group, to the N.E. of 

 Ahmednagar in the neighbourhood of Jamla. Wantra and Mundeti, 

 the outcrops of Idar granite are of smaller size and importance. 

 They are here much associated with rather similar tors of black 

 quartz-porphyry and also with ridges of Delhi Quartzite, which 

 they only doubtfully penetrate. The most southerly occurrences, 

 as at Berna and Wantra, are horizontally truncated and capped 

 by outliers of the Ahmednagar sandstone series. 



Throughout all this area it will be seen that the Idar granite 

 occurrences are as a rule restricted to the lower-lying portions of 

 the State. Granite has not been found to the north and east
