292 Notes on the South Mahratta Country, tyc. QNo. 160. 



S. Mahratta country; and there doubtless exist many other minerals 

 in its rocks now unknown, but which the researches of other and 

 abler pioneers than myself, and with more leisure, will not fail to elicit. 



Geographical position and extent of the various Rocks of the S. Mah- 

 ratta Country. 



Hypogene Rocks. Commencing on the South, we find the greater 

 portion of our area occupied by hypogene schists and argillaceous shales 

 and slates, reaching on the North from Gujunder Ghur from the edges 

 of the limestone and sandstone tracts ; and at Bangwari, fifteen miles 

 S. E. from Belgaum, basseting from beneath the overlying trap whence 

 they extend by Darwar and Kittoor, forming the base of the Western 

 Ghauts, and underlying the laterite of North Canara to the Sea on the 

 West, stretching into Mysore on the South, and into the great plains 

 of the Ceded Districts and Hydrabad on the East. 



Near the N, W. angle they are seen outcropping from the sand- 

 stones near Gokauk as a salbande at the edges of the overlying trap 

 formation along the N. bank of the Kistnah, in narrow zones along the 

 Western base of the Sitadonga hills. They are seen with granitic 

 rocks on the summit of the Ramghaut, and below it hornblende schist 

 occurs on the sea shore at Vingorla. 



Extent of the Limestone and Sandstone Beds. 



The Limestone. The Southern boundary of the limestone and its 

 associated shales has not been traced with accuracy, but we find it four 

 or five miles S. of Kulladghi. 



On the North Eastern extremity it emerges from the overlying trap 

 near Talicotta, is capped by sandstone at Mudibhal, but re-appears in 

 the valley of the Kistnah at Chimlaghi. A little to the S. W. it is again 

 overlain by the great mass of sandstone forming the Sitadonga hills, 

 but again is seen forming for the most part the base of the great plains 

 of Kulladghi and Bagulcotta, and stretching to the West to the sand- 

 stone ranges of Gokauk and Padshapoor which bound it to the West, 

 while the northern edge is fringed irregularly along the banks of the 

 Gutpurba by the overlying trap. 



Extent of the Sandstone. The sandstone and conglomerate ranges 

 usually skirt the great limestone plains as the sand and gravel shores
