Sketch-map of Geology of the Coast of Kincardineshire from Cowie to 

 Garron Point. 



Ur-PER Silurian (Downtonian). 



Owing to the discovery of fossils in beds overlying the basement 

 breccia, a considerable thickness of what has been regarded as Lower 

 Old Red Sandstone must be considered as of Downtonian age. The 

 succession of these rocks as shown in the coast section from Craigeven 

 Bay to Stonehaven Harbour is as follows (in descending order) : — 



9. Tuffs and volcanic conglomerate 



8. Brown micaceous sandstone .... 



7. Tuffs and tufaceous sandstone .... 



6. Grey sandstone and fossiliferous sandy shales and 

 stones (with fish-band) ..... 



5. Eed sandstone ...... 



4. Volcanic conglomerate and tuffs 



3. Grey and brown sandstones with thin red mudstones 



2. Purple sandstone ...... 



1. Basement breccia ......

The basement beds consist of breccias with intercalated thin red 

 sandstones and sandy mudstones. The breccias are made up almost 

 entirely of angular fragments of the igneous rocks and jaspers of the 

 underlying Cambrian (?) strata, but they contain also occasional 

 subangular and rounded pebbles of granite and schists. The un- 

 conformity which marks the base of the series may be traced along
