5Q BUNDELCUND. 



is the stripe that I have colored with the Bijawurs, west of the Dessaim 



and north of the breccia ridge ; its connexion with the latter is very vague 



and on the other hand the rocks in it are of a type not elsewhere seen 



among the crystallines — granular, quartzose, gneissose schists with much 



earthy base, and often charged with well-rolled pebbles of quartz. 



I did not detect any peculiar arrangement among the granitic rocks ; at 



all parts of the field one may find similar varieties ; small discontinuous and 



'„ .,. strangulated patches of earthy schists are not un- 



Type chiefly smceo- ° r J 



felspathic. frequent but the general type is highly siliceous 



and felspathic ; there are no extensive zones of the more earthy foliated 

 rocks, as mica or chlorite schist. Two felspars are easily detected through- 

 out, each is often exclusive of the other in the fully crystallized rock as 

 well as in those imperfectly so, but again, the two are often met in the same 

 rock ; even in the same well defined crystal both colors are found, so 

 it may well be doubted if they are different species ; I remarked how- 

 ever that wherever felspar crystals have been re-formed in the overlying 

 rocks at contact, they are of the red kind. There are veins of pegmatite, 

 of origin subsequent to the containing rock, and which contain either 

 felspar. 



Micas of several kinds also occur; the silver white variety I only found 



in rocks that were plainly of metamorphic stamp.

The strike of the foliation ranges between north- 

 west, and west south-west. 



The most remarkable, as certainly the most prominent, feature in these 



rocks of lower Bundelcund, are the great ribs of 

 Quartz. . , 



quartz that traverse the country ; they are trace- 

 able sometimes for 12 or 15 miles in a perfectly straight line, the mass 

 itself of pure milk-quartz is generally from 10 to 40 feet wide and it 

 stands out for the upper half of the height, which sometimes reaches to 3 or 

 400 feet, the base being sloped off by debris. Their strike markedly 

 contrasts with that of the gneiss, the great majority range between
