Wynne — Notes on the Geology of the Punjab Salt Range. 89 



coal crops at the base of the Nummulitic limestone hereabouts, but 

 the credit of this disoovery of the organio remains, at the lower level 

 just above the local boulder- beds, belongs entirely to Dr. Warth, 

 who has lived ere this, for years, in the salt range, as superinten- 

 dent of the salt mines and Salt Revenue Collector, and who has 

 lately been employed there by Government under the Board of 

 Works, to conduct explorations and boring operations along the 

 irregular, but laterally extensive, coal deposits. Being familiar 

 with the local geology, notices of which have largely entered into 

 his reports on the mineral ground ; my friend Dr. Warth was most 

 competent to search the country in even greater detail than my 

 own opportunities afforded means of doing, at any one particular 

 place ; and in this instance he has been most successful. 



The t sections of the range in and about this region exhibit the 

 following succession of beds : — 



11. Tertiary sandstone. 



10. Nummulitic limestone, with the coal beds 1 in a shaly zone at 

 its base. 



!a. Pale or light-coloured, and reddish sandstone. 

 b. Dark shales and olive sandstones with boulder-beds con- 

 stituting the " Olive series" or group. 

 These boulder-beds of g. b. resemble those of the Talchir group 

 of Central India, according to the descriptions given and also 

 verbal communication from Mr. W. Theobald. (I have not 

 seen the Talchir boulder-beds myself.) They occur generally 

 in the lower part of the Olive group, and they include a 

 variety of rounded and sometimes glaciated metamorphic 

 rocks, the glaciation of which was first noticed by Mr. Theo- 

 bald. 

 7. Eed flags usually covered by a mass of red clays, the flaggy beds, 

 characterised by their surfaces being often thickly covered 

 with pseudo-morphic casts of cubical salt crystals. The beds 

 have been doubtfully considered Triassic in my report, at the 

 suggestion of Dr. Waagen. 

 4. Pale magnesian, and silicious sandstone, and some shales — 

 beds often ripple-marked, generally quite unfossiliferous or 

 obscurely fucoidal.
