In addition to this eastern marginal appearance of this rock

more detail) there are a few other bands 

 developed as follows — (1) a band east of the Golwara calc-gneiss, 

 running N. and S. past Chandap and near Nawawas. (•_>) a small 

 area south of Wasan, and (3)' a poorly exposed band in the valley 

 between Matora and Semlia. All these areas are very scattered 

 and isolated from each other and sometimes from all other cooks 

 by the all-pervading alluvium,, just as was found to be the case 

 with the more southerly exposures of the calc-gneiss. 



The eastern exposures are, however, the fullest and most in- 

 teresting, and these must be considered in 

 Eastern exposures. ' 



some detail. We find them best developed 



in a string of outcrops a few miles N.E.. E. and S.E. of lined 

 Brahma in the neighbourhood of Walren. Dijio, Derol, Damavas 

 and Medh, localities which will be easily picked out on the map bv 

 the separate tint allotted to these rocks. In spite of their scattered 

 exposures it can be seen that they lie generally occupying an in- 

 termediate position between the calc-gneiss formation to the west 

 and the foot of the Delhi Quartzite hills to the east.

Walren, and with but a small intervening- 

 space, as near Medh. and although agreeing in the strike and 

 dip of their foliation planes — which latter is about 30° in an 

 east or south-east direction — there is no evidence of any interbed- 

 ding of the calc- and non-calc-series, the junction being somewhat 

 sharp and the change sudden and final from the one rock to 

 the other. The relationship of the non-calc-schists to the Delhi 

 Quartzite in the. other direction is also of the nature of a sudden 

 change with a distinct line of junction ; but in this case the junction 

 is much more complicated, and in certain features resembles an 

 eruptive unconformity, or at least one of great plastic deformation. 

 About this more will be said anon.
