| The age of the Carrock microgranite provides further evidence that both calc-alkaline and tholeiitic magmas were available during Caradoc magmatism in the Lake District. |
|
| The microgranite has a felsitic groundmass containing microphenocrysts of albite and orthoclase along with phenocrysts of corroded quartz and sporadic dihedral garnet. |
|
| Seven quarries around the western side of Threlkeld Knotts have worked the microgranite. |
|
| In some cases these dykes connect to small microgranite sills or laccoliths. |
|
| The later group contain more common basic microgranite xenoliths. |
