54 Brigadier Silvertop's Sketch of the Tertiary Formation 



mentioned in the manuscript from which the above account of 

 the melancholy fate of Vera la Viego w£js extracted. 



Aguilas^ Almazarron, Cartagena *. — Along the Mediterra- 

 nean coast from Vera to Cartagena, the tertiary deposit presents 

 no striking feature. It may, however, be traced in some little 

 flats at the base of the primary and transition mountains that 

 generally almost reach down to the beach, by the occasional ap- 

 pearance of its usual pectens and other shells, embedded in little 

 scattered masses of gravel or sandy marl. Such are represented 

 to be met with near Aguilas, in a memoir lately read to the 

 Society by Captain Cooke, R. N., although they escaped my 

 observation when I passed by this little seaport ; but between 

 Aguilas and Almazarron, and in the vicinity of the latter vil- 

 lage, a few patches of the formation containing tertiary shells, 

 were noticed. Almazarron may be cited as another locality 

 where numerous mineral productions and volcanic rocks testify 

 the direction of that hne of subterranean agency, to which allu- 

 sion was lately made, as will be more particularly mentioned in 

 a subsequent memoir. Near Cartagena the tertiary formation 

 is again well developed ; but as it is here seen on the northern 

 flank of the transition ridge that borders the Mediterranean, 

 this locality is not exactly included in the line of coast which I 

 have -attempted to describe, but will be noticed in another me- 

 moir, in which I shall endeavour to point out the various ter- 

 tiary deposits in, and the general geological structure of, the 

 province of Murcia.

Section 1. Represents the little tertiary tract contiguous to the upper 

 part of the town of Malaga. Between Malaga and the Cemen- 

 teri, Group 1. indicates the position of the lower or argillaceous 

 bed of the tertiaiy deposit : between the Cementeri and the base 

 of the mountainous country to the north, group 2, 2, 2, low hills 

 capped by the superior tertiary beds. 



• The patches of the tertiary deposit along the coast line from Vera to 

 Cartagena, belong geographically to the province of Murcia.
