Among the hills from A’mbad towards Paitan good sections are seldom seen, as most of the rocks there are much decomposed at the surface. The following section is taken from some of the lower scraps near Choti Pipalgaon on the Birh road. Starting with a reddish clay from six to nine inches thick in the bed of a nalla a little below the base of the hill, some purple amygdaloid follows, not much mottled, with the cavities and kernels coated with very little green earth, except near the cracks and joints, where this mineral is more abundant. The same rock higher up is of a reddish colour, with numerous small kernels, giving a total thickness of about twenty feet. Succeeding this for another six feet is some decomposed dolerite containing runs of calcareous matter. A thin band of reddish clay is sometimes seen above, about nine inches thick; and then a decomposed greyish-brown trap for twenty-five feet with numerous small vesicles and nodules coated with green earth, but the latter not very plentiful towards the top. Next comes a reddish vesicular trap six feet thick with very few nodules, which are not coated with green earth. Above this, along the steepest slope of the hill, are the usual decomposing dolerites for about fifty feet, weathering into basaltic kernels; and then another parting of red clay about nine inches thick, succeeded by purplish trap twenty feet thick, with a few cavities enclosing silicious minerals. This last trap, almost perpendicular, forms the scarp of the first terrace, and is also the rock of the cave excavations of Aurangabad and Elura. Above this rock, which is sometimes interstratified with anamesitc, are the usual traps more or less amygdaloidal and vesicular, with perhaps some hard basalt at the very summit.
