the Muschelkalk, Ssc 323 



zechstein. On the eastern side of the great basin, of which 

 the latter mass covers the western and northern edge, ano- 

 ther limestone occurs which is equivalent to the muschel- 

 kalk, or in other words, the muschelkalk, on the western 

 side of the Thuringerwald, here and there essentially chan- 

 ges its character, nearly in the same manner as the first 

 secondary limestone (magiiesian limestone) does on the sides 

 of the same basin. 



It is important to observe this singular change, since it 

 may afford us the key by which to recognise this deposite in 

 other countries ; it more particularly takes place in the 

 Coburg country. The muschelkalk forms a large platform 

 on the north of this town, extending towards Meinungen 

 and Neustadt ; the Monts Langenberg, near Coburg, are 

 still composed of the true muschelkalk, with siliceous no- 

 dules in its lower parts; but on the S.W. we observe only 

 deposites of a very magnesian compact limestone of a whitish 

 or whitish grey colour by the side of the oolite formation. 

 It contains small veins of magnesian carbonate of lime, and 

 Tery irregular nodules and strings of jasper, and a species of 

 chert or even coarse chalcedony, of a red, grey, and white 

 colour. The common fossils have altogether disappeared. 



This limestone, which is connected, as we have said, with 

 the new rod sandstone by an arenaceous limestone, forms 

 the top of Mont Eckcrsberg, of the Bucheberg, and of the 

 monts on the east of the chateau of Coburg. It is seen near 

 Bohrbach, Rogen, Lutzelbuch, and at Neuhofer-Muhle, 

 from whence it extends towards Banz, occasionally covering 

 the new red sandstone. On the east of Coburg, it forms a 

 small platform from Oslau to the Mahnberg, it reappears 

 near Ecinberg ; more to the S.E. a very narrow crest of this 

 limestone runs along small platforms of the true muschelkalk, 

 and in the end, we see this dyke, some feet thick, abut 

 against the latter limestone, near Kipfendorf, whilst the 

 true muschelkalk, after having formed four small platforms 

 between Coburg and Gestungshausen (the first on the E. of 

 Rohsbach, the second on the E. of Kipfendorf, the third to 

 the E. of Fechheim, and the fourth to the N. of Gcstungs-
