other outcrops, it is impossible to suggest how this calcareous rock 

 is related to the other Aravallis of this area. 4 fl j^, from $ mile 

 N.W. of Jesangpur. has much tremolite developed in it and it 

 suggests a comparison with the similar rocks associated with the white 

 pyroxene rocks of Bamanvada (see p. 69). 



A striking and interesting feature of this Bamanvada-Jesangpor 

 area is the occurrence of a peculiar and well- 

 White pyroxene and maY ^ e( { band of white pyroxene-rock, pro-

minently seen on the right bank of the Meshva 

 river about 1 to 11 miles S.S.W. of Bamanvada. Here it is exposed 

 continuously for § mile in an outcrop striking N.byW.. that is, 

 parallel to the river at this place. It appears interbedded with 

 some calcite and pale amphibole-rock and also with some quartz- 

 schists, through a thickness of about 60 feet or more. In the direc- 

 tion of the river-bed it is underlaid by muscovite-biotite schists 

 with translucent quartz layers as already described, and it is over- 

 lain by more schists with a profusion of white quartz veins, the 

 latter, with the white pyroxene band at its base, forming a low 

 mound or strip of rising ground lying parallel to the river bank. 

 The dip of the beds is W.byS. at about 50°.

 same set of rocks are seen at the following places : J mile higher up

 joins the Meshva $ mile W.S.W. of Bamanvada, again near Sunak 

 and near Kheradi in the stream-bed (f\ 5 ), and also about 2 miles
