Gabbro is not granite.
good point :)
However the Skye gabbro is unique and not similar to any other. In many places when I was there it tended to switch gradually to something more like granite, but never very clearly.
Looks like a good page anyway. :) I'm not sure but some people may call gabbro 'black granite' or something like that.
Gabbro is definitively not a granite. Granite consists mainly of quartz (20-60%), alkali feldspar and mica. Gabbro consists of mainly plagioclase, up to 5 % quartz, pyroxene and olivine, thus linking it to the basaltic plutonites.
Quartz and feldspar rich gabbros can look similar to dark granites, maybe thats the point!
ok, ok, ok guys... corrected ! :)
I think I'll give you some homework LOL Pop outside the city and compare the rocks on the top (or SE/S side) of Sleza Mtn and those on its NW flank at about 400m. :)
It is a fantastic page anyway !!! What a wild and rugged landscape ... Cheers, Michael
