A paper was read, entitled " On the Tertiary deposits of Lower 

 Styria ;" by the Rev. Adam Sedgwick, Pres. G.S. F.R.S. &c. and 

 Roderick Impey Murchison, Esq. Sec. G.S. F.R.S. &c. 



The region described in this memoir, is a great depression on the 

 north-eastern watershed of the Alps, in which has been accumu- 

 lated a very fine series of tertiary deposits terminating eastward in 

 the plains of Hungary. This great trough or bay of Lower Styria, 

 which is intersected by the river Mur, is bounded on the west by the 

 Schwanberg Alp ; on the north by the calcareous chain of Gratz and 

 the primary mountains of Pettau, Vorau, and Hartberg ; on the south 

 and south-west by the Matzel and Bacher-Gebirge. 



Two principal sections are offered, explanatory of the views of the 

 authors : — The first from the Schwanberg Alp to Radkersburg, in a 

 direction nearly east and west, develops in an ascending succession 

 all the tertiary deposits : — The second, from south to north, is con- 

 fined to the youngest zone of tho.se deposits, and exhibits its relations 

 to the volcanic rocks of Hungary. 



I. Section in an ascending order of the Tertiary formations between 

 Eibeswald on the west and Radkersburg on the east. 



a. The lowest members of these deposits consist near Eibeswald, of 

 micaceou.s sandstones, grits, and conglomerates, made up of the de- 

 tritus
