The allotriomorphic compact brown hornblende encloses felspar crystals and large patches of 
colourless fibrous hornblende. The opaque mineral is titanomagnetite pseudomorphous after biotite.

Oatland Complex. Basic fades. X 20. 
The large individuals of colourless fibrous hornblende are now chloritised with separation of 
much calcite and epidote. A few blades of actinolite are just discernable near the centre of the section. 
Cloudy, allotriomorphic felspathic matter completes the mineral content.
