Kendall : Geology of the Vale of Eden. 



The geological succession is shown in the following table, 

 and, with the exception of the Upper Carboniferous, the whole 

 of the rocks will be examined.

Skiddaw Slate. 



Igneous rocks occur in great variety, and these will be 

 studied in two principal areas — one near Dufton, and the other, 

 Carrock Fell, made classic by the researches of Mr. Harker. 



The Whin Sill will be examined, but, unfortunately, the 

 limits of time will not permit a visit to the Renwick-Arma- 

 thwaite dyke, which is the continuation of the Cleveland dyke. 



The Skiddaw Slate is generally a dark lustrous slate, with 

 strong cleavage. It is so broken up by faults and thrusts, 

 and so rarely fossiliferous, that, despite its enormous thickness 

 and many excellent exposures, a clear succession is very 

 difficult to establish. Near Carrock it has undergone meta- 

 morphism by contact with igneous intrusions, and beautiful 

 examples of Spotted Slate and Chiastolite Slate will be seen. 



The Borrowdale rocks are entirely volcanic (Andesites, 

 Basalts, etc.). They will be seen at Eycott Hill, near Carrock 

 Fell, and Rhyolitic lavas of late (Coniston Limestone), date 

 will be well seen at several places in the Cross Fell inlier. 



The Coniston Limestone Series to be studied in the Inlier, 

 include black and grey shales, often charged with beautiful 

 brachiopods, trilobites and graptolites, and a magnificent 

 limestone — the Keisley or Staurocephalus Limestone, that, 

 besides containing abundant corals, brachiopods, gasteropods.
