PAUL XOETH-H.UNGAEIAN DEPOSITS. 



On the Succession of the Uppee Teiassic, Eh^tic, and Oldee 

 LiASSic Deposits near Hommona in Noeth Hukgaet. By M. 

 Paul. 



[Proe. Imp. Geol. Institute, Vienna, 31st July, 1869.] 



The succession of these deposits in descending order is as fol- 

 lows : — 



White- veined Limestones, occasionally dolomitic, constantly asso- 

 ciated with layers of quartz. 



Grey Marly Shales, alternating with compact Limestone -beds, 

 containing Pentacrinites, Lima (?), and other indistinct organic 

 remains (24-28 feet). 



Limestone A^ith Plicatida intus-striata, Ostrea Haidingeriona, Pecten, 

 &c. (6-12 feet). 



Limestone, with large Megalodon sections (3-4 feet). 



Limestone, with Terebratida gregaria (6-12 feet). 



Dolomitic Marl (3 feet). 



Limestone, with Lithodendm (9 feet). 



Limestone, with abundance of Terebratida gregaria, which is asso- 

 ciated in the deeper nodular layers with Cephalopods and Gas- 

 teropods (24—30 feet). 



Marly Limestones, with Plicatula intus-striata, Ostrea Haidingeriana 

 and Pecten (6 feet). 



Soft dark Shales (3 feet). 



Dolomitic Marls, more compact (3 feet). 



Soft Marls, alternating with more compact beds (3 feet) . 



Dark red, very crumbly Marl-shales (12-18 feet). 



Quartzite and coarse Quartz-sandstone, very like that occurring in 

 the Lias (30-36 feet). 



Dark Shales, with distinct, compact beds, which are sometimes 

 quartzitoid (36-48 feet). 



Variegated Marls in thin layers, somewhat dolomitic (120-180 

 feet). 



? Dolomitic Breccia. 



The white-veined Limestones are overlain by Dolomites contain- 

 ing BeJemnites, and these by Limestones with hornstone and traces 

 of Crinoidal Limestone, which may represent the superior Jurassic 

 deposits. 



This section proves that the white-veined Limestone, so widely 

 spread in the Carpathians, and generally referred to the Trias, 

 belongs, with its subordinate Dolomites and Quartzite-beds, to the 

 Lias. It is not, however, the lowest stage of that formation, as is 

 proved by the Quartzites of the Little Carpathians, between which 

 and the Kossen beds a great deposit of dark-coloured Limestone is 

 intercalated. This section reveals another fact of interest with 

 regard to the Kossen beds, namely, that Bivalves and Brachiopods 

 may alternately predominate repeatedly, so that they do not stand 

 to each other in the relation of constant stratigraphical horizons.
