The analyses of the dykes show by the excess of lime and 

 magnesia over the alkalies, that the plagioclase belongs rather 

 to the basic series ; and the large amount of lime and practical 

 absence of potash from the plutonic rock, taken in conjunction 

 with the high silica percentage, shows that it is to be regarded 

 as a granodiorite rather than a granite.
