DALING AND DAEJILING SERIES. 39 



on the other hand, one cannot but be struck by some points of resem- 

 blance between the latter rocks and those included in Mr. Medlicott's 

 1 Krol group' at the top of his Himalayan series of the north-west.. 



Chapter IV. — Baling and Ddrjiling* Series. 



Sections are frequently obtainable, showing the junction of the 



Relations of Baling Damudas and Daling series. In every case which 



beds to Damudas. came under my notice, the two series are sensibly 



conformable to each other, although generally there is a very marked and 



sudden lithological change. 



Thus, in a deep gully which joins the Lehti naddi from the south 

 (p. 28) the strata dip to the south at about 30° and are inverted, 

 the Daling slates being underneath. The last -mentioned rocks, of which 

 three or four hundred feet is included in the section, consist of alter- 

 nating light green and dark greenish -grey, slightly greasy slate, the 

 latter variety looking black at a little distance. Some of these alterna- 

 tions are 50 or 80 feet thick, others only an inch or two, and they prove 

 that, here at least, the fissile planes coincide with the bedding. Resting 

 on these beds, at a clearly defined horizon, is slaty Damuda sandstone. 

 The thin alternations of variegated slates at the junction do not bring to 

 light the least unconformity ; and the Damudas include one or two thin 

 layers of light green slate, similar to that below, at a few inches from 

 the base. Above this there is some hundred feet of highly altered 

 Damudas, comprising foliated quartzose schists, thin seams of coal, and 

 beds of carbonaceous schist, &c, whilst carbonaceous matter is completely 

 absent from the slates below. 



Sections are obtainable on the southern face of Latpanchor, and in 

 the Ranjang naddi, where the Damudas dip at 5° and 15°, and in 



* The gneiss above the Daling beds is called ' Sikkim gneiss' on the map, but ' Dar- 

 jfling' is a preferable name, as the gneiss of Kanchinjinga in Independent Sikkim may be of 

 a different age.
