DELHI QUARTZITE SERIES. 83 



North of Mundeti, and separated by about a mile of alluvium 

 from the Mundeti series (already described p. 



North of Mundeti. „ . , . * r 



do) the more loltv. northern ranges of the 

 Delhi Quartzite are largely outside the boundary of Idar State. 

 Their southern prolongations, however, forming the 1.150 feet peak 

 at Kathroti. the 1,033 feet peak and the 1,607 feet peak, together 

 with the bays between them, have revealed the steady, steep 

 dips to E.S.E. and the line of discordance between the Delhi 

 Quartzite and the Mundeti beds as described in the section devoted 

 to the Mundeti series (see p. 00), and have elicited the im- 

 portant fact that none of the Mundeti series of calcareous and other 

 rocks (so well developed in the 1,333 feet hill, 2 miles north of Mundeti 

 and in the group of straggling outcrops near Sisasan) are continued 

 into these hills, although their strike (if there were no discontinuity) 

 would carry them directly in that direction. The outcrops of 

 Delhi Quartzite in these northern spurs are in fact sharply separated 

 from the more or less uniform, and somewhat less elevated, range 

 of Delhi Quartzite at Vasai and Jhumsar by a plain of alluvium 

 and Mundeti outcrops, some 4 miles in extent, that completely 

 interrupts them except for two minor, very broken extensions, 

 as indicated by two little sets of knolls and low ridges, all being 

 of quartzite. The first of these comprises the ridge N. E. of Mundeti 

 and that between Mundeti and Vasai (which appear to form a 

 synclinal trough with marked platy structure), whilst the other 

 is much less well-marked and embraces the 980 feet knoll S.E. of 

 Kasangad and the 799 feet hillock north of Ghanti. 



At Vasai fine-grained, pink or purple and white, splintery (fissile 

 or cleaved) uuartzites or quartz-schists are 

 exposed in the little south-westerly termina- 

 tions of the spurs given off from the 1,127 feet peak, and seen dipping 

 at 30° to 4.0° E.S.E.. which is the same in direction and amount 

 as that in the Mundeti series. 



The expanded, and somewhat elevated hill-mass of Delhi Quart- 

 zite lying to the south of this and to the west 



West of Man. , • ' °. . ( 



or Mau, is a curious tract or country, com- 

 posed of pink and white quartzite of the usual kind. It keeps 

 a low elevation, and consists of round-backed undulatory ridge- 

 lets. The evidence of dip, derived from beds of varying degrees 

 of massiveness, is fairly satisfactory across the main area from 

 Kuvava via Munai to Mau. where it appears to be E.S.E. or S.E.
