This lab concentrates on high pressure eclogites and some medium pressure corona gabbros in the Caledonides of western Norway. These rocks all have broadly basaltic compositions, and were metamorphosed during the Paleozoic Caledonian Orogeny. The high pressure rocks were brought rapidly enough to the surface so that some eclogites scarcely have any evidence of retrograde metamorphism.
Geology
Simplified geologic map of Norway, Sweden, and Finland. The photos below are from Norway, from the Trondheim area and along the coast toward Bergen. the blue line has nothing to do with the photos below.
