14 JONES: SOUTHERN COAL-FIELDS OF SATPURA GONDWANA BASIN. 



The metamorphics consist of the usual gneisses and schists, and at 



one point between Oomerghor (E. Lon. 78 38') 

 Petrologv. . 



and Dhadra (E. Lon. 78 40 ) I found schists 



containing numerous garnets.

which they first put in an appearance, the lal- 



chirs are represented along the whole of the area from near Dala 



village (E. Lon. 77 44') on the Pench river in Chhindwara, to a 



point south of Parsuda near the Moran river in Betul, though for a 



short distance between Khursadeye and Mooeari they are covered by 



trap. 



As regards the Talchir-metamorphic boundary, it is, with the ex- 



Talchir-metamorphic ce P tion of that P ortion belonging to the small 

 boundary. area f Talchirs exposed south of Harai (E. Lon. 



78° 5 1 ')) concealed at the eastern end by trap. In this little patch 

 there is a very good exposure of the Talchirs, in the Kopadoh 

 stream running past Khursadeye (E. Lon. 78 50'), from the point 

 where the stream leaves the Barakars to its junction with the Puthreye 

 river and for a short distance up the Puthreye itself. The Talchirs 

 here consist of the usual finely jointed shales, containing numerous 

 transported boulders varying much in size, from that of a hazel 

 nut to 2 or 3 feet in diameter. To the east of the junction of 

 the Kapadoh and Puthreye streams the Talchirs are exposed for a 

 short distance in the latter, and then a trap dyke passes across be- 

 yond which the metamorphics are seen. The Talchirs are again ex- 

 posed in the small streams to the north of the Puthreye. The rocks 

 here do not present the appearance of having undergone disturbance, 

 though owing to the unstratified and miscellaneous character of the 

 boulder bed it is impossible to tell what the dip is.
