Vol. 52.] DEPOSITS, ETC., IN SUB ALPINE SWITZERLAND.

springs of Baden issue from fissures between the Keuper and the 

 Liassic strata. The horizontally stratified conglomerate forms a 

 cliff about I kilometre in length, and juts out at intervals from 

 loose gravel and boulder-bearing moraine, which is banked up 

 against it and fills the Badeu basin to a depth of about 20 metres. 

 A large artificial cave excavated in the conglomerate and a pit 

 close by in the loose gravel and sand reveal a marked difference 

 between the two deposits, the former being, in my view, a remnant 

 of Cavernous Na- »

gelfluh which es- 

 caped erosion, 

 while the latter 

 contains small 

 lumps of the older 

 conglomerate , 

 and must therefore 

 be the younger 

 deposit of the two. 

 The Nagelfluh, 

 which is about 6 

 metres in depth, 

 rests on about 1 

 metre of sand, and 

 this again rests 

 on marl and gyp- 

 sum of the Keuper 

 formation. At the 

 side of a road 

 above the cliff just 

 mentioned, there 

 is another rem- 

 nant of the same 

 conglomerate, 

 and similar rem- 

 nants are buried 

 probably at other 

 points of the 

 Baden basin ; at 

 all events, several 

 others conspicuously project from the vineclad slope of the gravel- 

 and-moraine terrace between Baden and Turgi. This conglomerate 

 exhibits all the characteristics of Deckenschotter and, in my opinion, 

 must be regarded as such. 



Another remarkable section of Deckenschotter occurs on the hill 

 on the left side of the basin, near a point called Eichthal, close to a 

 sharp bend of the high-level road from Baden to the Gebensdorfer 

 Horn, and at contour 480. The exposure (fig. 3, p. 502), in which 

 a large artificial cave has been excavated, exhibits an exceedingly 

 hard, compact, irregularly stratified conglomerate about 6 metres in
