One of the reasons that Cadaqués and the Cap de Creus is so
stunning, is its beautiful geology. The rocks here were mashed
up when the Pyrenees were formed, and are mostly metamorphic
schists which turn a lovely golden colour in the Mediterranean
sun. On top of that, this is one of the wildest spots on the
Costa Brava in the winter (Costa Brava means "wild coast ") ,
and the migmatites and schists have battered and eroded by the
Tramuntana wind and a sea that can look as if it is boiling in
the strong winds. (A migmatite is a type of rock that formed
under extreme pressure and temperature: a partial melt.
Migmatites are halfway between an igneous and metamorphic rock.
A schist is a medium grade metaphorphic rock that has been
squashed into flakes or slabs. Schist is derived from the Greek
meaning "to split"). Interspersed within this mash of schist is
dazzling white blocks of pegmatite- basically molten rock that
percolated up through the gaps in the rock at the end of the
"orogeny" or mountain building. The
