196 FOOTE : SOUTH MAHEATTA COUNTRY. 



The beds exposed in the section are — 



4. Quartzite and gneiss shingle of uncertain age. 



3. Weathered basaltic trap. 



2. Red sandy marl with three or four sandstone partings containing Unio 



(Deccanensis ?). 

 1. Decomposing whitish amygdaloid trap.* 



The Unio beds are about 20 feet thick^ aad there can be little doubt 

 that they were formerly continuous with those of the Mamdapur section. 

 The fossil Unios in both sections are very well preserved, the interior 

 nacre even being* preserved in some instances. They do not seem to have 

 been exposed to so severe a pressure as the Todihal IBhysas, or else the 

 matrix they were enclosed in had acquired more power of resistance ere 

 the pressure supervened. . 



The most important example of intertrappean beds in which no fossil 



remains have been found is to be seen at Supudla 

 Supudla sections, 



(Soopudla), six and a half miles north of Ramdurg-, 



where the following* set of beds rests upon the basement trap-flow, and 



is well exposed in the slope east of the village : — 



6. Trap, 



5. Red bole, a thin band. 



4. Red and white mottled sandy marl. 



3. Friable sandstone. 



2. Conglomerate sandstone with quartzite pebbles. 



1. Trap, 



The beds lie horizontally, and may safely be estimated to be 20 feet 

 thick and may possibly be more. 



About two miles to the south-east in the left bank of a nullah 

 running" south into the Malprabha is a small section exposing a bed of 

 sandy red marl resting on a coarse conglomei'ate of quartzite shingle, at 

 the base of which are large angular and sub-angular masses of quartzite 



* The section represents the beds north of the village in order to introduce the curious 

 shingle bed No. 4. The JJnios were found a few dozen yards south of the village.
