WYNNE : GEOLOGY OF THE SxlLT RANGE IN THE PUNJAB. 



At the base of the " salt=crystal zone^^ is a coarse gravelly sandstone 

 band, and further up many of the harder bands have a purplish gray 

 colour. The salt-pseudomorphs occur here again^ with ripple marks 

 and casts of desiccation-cracks on the flags, and there is a considerable 

 development of the red clays or shales belonging to this zone, some of 

 which are variegated with green spots. The largest part of the shales 

 here occur (unlike those to the east) in the lowest half of the group. 

 The "olive group ^^ above contains boulder conglomerates, some of the 

 boulders in which measure two and three feet in their longest diameter, 

 and in a bed of soft, weathered green sandstone are the casts of large 

 bivalve shells, before alluded to as of cretaceous appearance.
