MINERALOGY OF THE OCHILS. 



rally possesses characters intertnediate between 

 those of basalt and clinkstone ; from which cir- 

 cumstance, I have been induced to adopt the name 

 of Basaltic Clinkstone, which applies equally to 

 every variety. 



Its colours are blackish- grey, blackish-brown, 

 and sometimes it is much ironshot, particularly 

 at the summits of the lower hills. Its fracture is 

 slaty and rough, and in general it emits the clink- 

 ing sound to which the species owes its name. 

 Beautiful specimens of an amygdaloidal variety 

 occur between Abernethy * and Kinross. 



The dip and direction of the stratified portions 

 of this clinkstone, correspond with the general dip 

 and direction. 



IX. Greenstone, 



Throughout the district which extends from 

 Parton Craigs to Newburgh, the clinkstone fre- 

 quently passes into greenstone ; and in the imme- 

 diate vicinity of the latter place, it appears distinct- 

 ly columnar, though its relations to every other 

 rock are wholly undefined. 



It is not improbable, from similar greenstone 

 being found in higher portions of the hills between 

 Newburgh and Woodhaven, that it alternates with 



* The hills in this district are very picturesque, and have 

 (I believe) approj^riate names^ though I could not learn them, 

 as every shepherd furnished one of hiis own.
