DECCAN TRAP SERIES. 47 



few feet lower down than the limestones. On the other hand, the 

 contact of the upper heds and the overlying trap is often clearly exposed. 



Fossils are not very easily got out from the exposed surfaces, nor are 

 many to he seen, except when the quarries are re-opened at the end of 

 the rains and when the outcrop and the debris thrown out during the 

 previous working season have had some time to weather. 



Between this outcrop and the village of Katem (half a mile to the 

 Two [outcrops, doubt- west), a further trench has been opened up in 

 fully of the same band. li mes tones which appear to belong to another and 

 lower band ; but this is not sufficiently clear, as the dip is very low in 

 both bands, while the second of these is rather to the south-west of the 

 first, so that by the mere flatness of lie it is possible that the latter may 

 be a continuation of the former. I think myself that there are two 

 separate bands, because the rocks differ in some respects, and no fossils 

 are known from the western outcrop. The natives (and the views of 

 quarrymen who have worked from their childhood at these beds are 

 not to be lightly thrown aside) say that the two outcrops belong to one 

 and the same band. One thing is clear, — the western outcrop is also 

 underlaid by trap. 



The limestones of the band nearer Kateru are on the whole much 

 more crystalline than the rocks in the fossiliferous band. 



The trap, both above and below the limestone bands, is a dark-green 



or greyish compact basalt, very much weathered

all over the outcrops and well in below the surface. 



It has a strong tendency to separate in rounded masses and blocks, with 



rudely concentric laminae surrounding cores of the solid unweathered 



rock ; and so much is this the case that it has been found very difficult 



to obtain blocks large enough for the irrigation and canal works in the 



district. There is an indistinct sort of lamination parallel with the 



strike of the intertrappean beds when vertical surfaces are exposed, as 



near the quarries ; but there is no thick enough exposure anywhere on 



the slopes, either here or in the Pungadi field, to show any such bedded 



lie as is developed among the traps of the Deccan proper.
