What started as a simple fun trip with some friends to Lofoten Islands in northern Norway, just became a unique geological experience. This, because I think that, as a geologist, it is completely impossible to separate fun from my profession while traveling. It's just amazing to mix your profession with your favorite hobby.
Trying to understand the rocks, the configuration of the landscapes and their phenomena, is simply priceless.

This time I got completely impressed with the beauty of the Fjords in Lofoten (help: what is a fjord? well basically, a fjord is a narrow and deep channel that allows the sea to enter to the land. They can be several kilometers long, so they are often confused with rivers or lakes, and can reach great depths, exceeding 1000 m. These geomorphological units are the product of sea flooding of valleys created by glacial activity).

Hiking through the
perfectly carved U-shaped valleys left me speechless (above mentioned glacial
valleys). In each valley, it was possible to appreciate the sediments associated
with the activity of the glacier, that is, the Moraines (frontal and lateral), till
and reworked proglacial sediments.

In addition, the typical
vegetation of Tundra is impressive (help: what is Tundra? In simple words, it
is a biome characterized by the lack of trees, the soils are mainly covered
with mosses and lichens, characteristic of circumpolar latitudes. The subsoil
is almost permanently frozen). This vegetation covered the base of the mountain
chains and snowy hills, contrasting in a perfectly artistic way and offering a
breathtaking view.

What about lithologies?
Well, broadly all those landscapes are conformed by a Precambrian basement
represented by an Archean and Paleoproterozoic metamorphic complexes of ortho-
and paragneisses, intruded by anorthosites and suites of charnokite-granites.
This basement is in tectonic contact with amphibolites and paragneisses, which
were intruded by tonalitic magmas at 470 Ma. Subsequently, at the top of the
sequence, in a rather complex structural context, volcano-sedimentary sequences
are found, ranging from the Permian to the Paleogene. These volcano-sedimentary
sequences are part of the sea floor between Greenland and Norway. All these
units are in well-marked tectonic contacts.

Finally, in addition to the geological stuff, the sunsets, perfect beaches, rainbows, snowstorms, the strong rain and a whole bunch of climatic phenomena associated with these high latitudes, make the Lofoten Islands one of the places. I have enjoyed a lot being a geologist.

If you are a geologist and
feel the same as me while traveling, let me congratulate you.
You have a beautiful
profession!
