Wall defining the south-west ridge of Rhobell Fawr The path down the south-west ridge of Rhobell Fawr follows this wall to Bwlch Goriwared.
Here on the lower slopes, the wall divides the hillside into the colourful heather on the eastern side and coarse grasses to the west. The Cadair ridge is in the background.

Coed-y-Brenin Porphyry Cu-Mo Deposit - Phyllic Zone Porphyry copper deposits are of a major economic importance due to the high tonnage (but often low grades) of copper, molybdenum and gold. This deposit contains 200Mt of ore at 0.3% Cu with some Mo and Au. It would be economic only through opencasting, which I can't see happening any time soon!

Hydrothermal and magmatic fluids circulate to create alteration zones. The ore is usually hosted in the outer edge of the stock. 

Potassic zone, usually an igneous stock (volcanic magma chamber). 
Can be rich in secondary orthoclase, quartz, biotite and chlorite/sericite. 

Phyllic zone, altered host rocks. In this case volcanics and sediments.
Pyrite rich (10-15%), quartz, sericite, chlorite and illite. 

+/- Argillic zone. Varies in size, clay alteration. 

Propylitic zone, always present. Lightly altered with pyrite, chlorite, quartz, carbonates and epidote. 

This shows the phyllic zone. The pyrite has oxidised to produce the red stained colour.
