AND TRIAS OF CENTRAL EUROPE. 395 
Dyassic strata all round the northern end of the Thiringerwald. 
The Bunter strata not only lie, as I have just shown, unconformably 
against the Zechstein series on the side of Gopelskuppe, but they 
lie, as traced round the flanks of the mountains, against different 
members of the Dyassic Series. 
(1) Between Mosbach and Kittelsthal the Zechstein is overlain 
transgressively by the Bunter, so that the latter extends up an 
ancient bay of the old Thuringia land, and rests against the mica- 
schists on the one side and the Rothliegende on the other. 
(2) At both ends of Gdpelskuppe the Bunter overlaps the 
Zechstein and rests against the Rothliegende. 
(3) For some miles along the Hérsel Valley the Bunter, which is 
visible at the foot of the Ramsberg, passes under the alluvium of 
the Horsel (according to Prof. Senft) and reposes upon the Roth- 
liegende of the hills which extend N. W. from the Wartburg. 
(4) Lastly all round the western side of the northern end of the 
Thuringia Bergland the Zechstein series comes in again from the 
village of Brandenburg (at the junction of the Werra and Horsel) and 
continues all down to and beyond Schweina. The dip (about 25°) 
of the Zechstein series is here plainly to the S. W., as is well seen 
about Eppignellen and Fortha; while in all the cuttings in which 
the Bunter sandstone is observed from the latter place to Salzungen, 
the strata appear to be horizontal, as in the sketch section here 
given.

Prof. Geinitz insists very strongly upon the pronounced uncon- 
formity of deposition of the lowest Bunter strata upon the eroded 
surfaces of the Upper Zechstein. He points out * that the conformity 
upon which Murchison insisted is only apparent, and that it was 
only from insufficiency of observations that he was misled on this 
point. It follows of course that wherever (following Murchison) I 
have spoken elsewhere of the Trias of Germany following conform- 
ably upon the Dyas, all that must now be considered as unsaid. 
There is, it appears, no transition in Central Europe between 
the Dyas and the Trias; and if such a transition is to be found else-_ 
where, either in Russia or in the Alps, the fact only seems to 
emphasize the more the break between the two systems in Germany.
