it not for similar sections elsewhere that suggest questions on the 

 lines of those with reference to the Bamanvada white pyroxene 

 (diopside) series. There is, first, a dark-grey quartzose dolomite 

 with quartz stringers— s 2 7 r, 3 (12410) and 4 ^ a — the passage ap- 

 pearing to be a regular conformable one with interbedding — all plain- 

 ly visible in the naked rocks of the river-bed. The dark dolomite 

 is succeeded by a little white tremolite-calcite rock, jj 2 7 - 4 and 4 2 2 ° 8 

 (12412), and that in turn is followed by pale dolomites with filmy 

 layers of steatite, — 4 2 2 \ (12413) — exactly reproducing a rock that 

 will presently be described in more detail associated with the 

 steatite of the Dev Mori-Kundol exposures. A detailed search above 

 the village along the strike revealed none of the magnesian and cal- 

 careous rocks extending up into the ridge ; but, inasmuch as the 

 height of the latter is only about 400 feet above the plain at Khercha. 

 the anticlinal structure of the hill would hardly be able to accom- 

 modate them together with 500 fit. of the Delhi Quartzite, unless 

 the dip were very steep. A sketch view of the hill outline as seen 

 from the river near Khercha is added (see text fig. 18) with

described, the rest of the river-bed up to Samalpar gives no 



exposures, whereas on the analogy of the Dev Mori-Kundol section 



(see p. 99) we should expect dolomite or other magnesian rocks 



o underlie the surface here. The problem then is how does this
