24 GEOLOGICAL MEMOIRS. 



The grey and schistose marly Umestones of Nousberg (between 

 Trente and Gardolo) bear a striking resemblance to the Neocomian 

 deposits of the North Alps ; but have not yielded any fossils.

On the Iron-deposits of the Circle of Jaslo, in Galicia. 



By M. LiPOLD. 



[Proceedings Imp. Geol. Instit. Vienna, Nov. 11, 1856.] 



The southern portion of this part of Galicia, as far as the frontier of 

 Hungary, consists of low hills, having, on an average, an altitude of 

 2800 feet above the Adriatic, and belonging to the Beskid subdi- 

 "\'ision of the Carpathian chain. The sandstones and calcareous and 

 argillaceous marls and shales which compose it belong to the Upper 

 Carpathian Sandstone, corresponding to the Upper Cretaceous group. 

 The general strike of the beds is N.W.-S.E., and their dip S.W. 



The iron-bearing rocks in the territory are analogous to those 

 known in the more distant W. and E. portions of the Carpathians of 

 Galicia. Two ferriferous zones, striking and dipping parallel to each 

 other and to the imbedding strata, may be distinguished ; and a mass 

 of white quartz -sandstone, about 1000 feet thick, is intercalated 

 between them. The outcrop of one of these zones is known along a 

 line of 5 Austrian (about 25 English) miles ; that of the other, for 

 about 4 Austrian miles (about 20 English). Both are composed of 

 a series of inch-thick layers of iron-ores, alternating with sandstones, 

 marls, and shales. 



The ores are clay-iron-stones and sphaerosiderites, with from 18 

 to 36 per cent, of metallic iron. The highest amount of raw iron 

 extracted from them by metallurgical operations is 29 per cent.

On some Fossils /ro?w Raibl in Carinthia. 

 By Fr. von Hauer. 



[Proceedings Imp. Acad. Vienna, March 1857.] 



A SERIES of fossils collected by M. Melling from the Raibl-strata*, 

 and presented to the Imp. Geol. Institute, has been examined by 

 Fr. von Hauer, who determines fifteen species of fossils from these 

 beds. Five of these species, occurring also in the St.-Cassian-beds, 

 prove the Baibl-beds to belong to the Upper Triassic series. The 

 fossil fauna of Raibl, however, bears 'a peculiar and distinct fades ^ 

 characterized by the nearly complete absence of Brachiopods and 

 Cephalopods, by the scarce and dispersed occurrence of Gasteropods, 

 and by the predominance of Bivalves, especially of forms hitherto 

 exclusively met with in the upper portion of the Alpine Trias.

* See also page 20. This particular series of deposits was first noticed by 

 Boue, and afterwards described by von Hauer, Foetterle, Peters, and Stur, in 

 other localities of Carinthia, in CarnioUa, in the Venetian Alps, and in the Alps of 

 Lombardy, where they had generally been confounded with the Muschelkalk.
