Lofoten, one of Norway’s great grandfathers?

A couple of weeks ago I drove down to Unstad in Lofoten for a few days to visit friends and surf.  Lofoten is an archipelago west of Northern-Norway, about 6 hours’ drive south of Tromsø, known for its stunning scenery with whitewashed beaches and mountains rising dramatically straight from the sea. Unstad is one of the three top spots in Norway for surfing. Absence of waves, however, led us to hike mountains instead.

Norges unike skjærgård

(Norways widespread coastal platform – English version below)

Normalt tilbringes påska i fjellet, i år kombineres fjell og hav på segl og ski, langs norskekysten fra Tromsø til Ålesund. I realiteten ser det ut til at tre dager i Lofoten kanskje blei den skikjøyringa me fekk. Snart i Røyrvik nå med sikte på Sunnmørsalpane, men mildvær og regn har prega dei siste dagene langs kysten fra Svolvær, i tillegg til kraftig motvind og sakte gange. Vestfjorden fra Svolvær til fastlands-norge var et reint mareritt med 2-3 meter krappe bølger og sterk vind prega av kvalme og dårlig befatning. Letta då me kom til Nordskot og kunne seile innaskjærs. Akkurat dette ”fenomen” legger grunn for neste blogg-innlegg. Medan bølgene nå herjer opp i 4-5 meter lenger ute,  seiler me i nesten flat hav innaskjærs. Se bølgekart under som eksempel, hentet i dag fra windyty.

Imposing dolomite marble cliffs also called “Norwegian Snow” on Storfjellet in Breivikeidet (Troms, Norway)

Norwegian version below.

Saturday, two friends (Morgan and Sten-Andreas (also a geologist)) and I went ski touring on Storfjellet in Breivikeidet, Troms. The days are so much longer now, and even though we had bit of an alpine start, we walked in sun most of the time. Nice to feel that the sun is starting to warm again after a couple of months of polar-nights.

Me and Morgan studying a little outcrop or block of rock on or way up the mountain, it got our attention because of the rare color. Turned out to be the first clue of what later to come! Picture: Sten-Andreas Gundvåg

Diamonds in the skyline of Tromsø?

All underlined words are defined under the Dictionary tab of our blog! (Norwegian version below)

There are two types of rock that typically host diamonds. Kimberlites and Lamproites are igneous rocks that originate deep within the mantle (usually 150-450 km deep). Diamonds form within the mantle when carbon is subjected to extremely high pressures, and then they arrive at the surface when magma from these depths carries the diamonds up to the surface. The magma then cools into either Kimberlite or Lamproite with diamonds trapped inside. There is an additional rock type that can contain diamonds: Eclogite. Unfortunately, the diamonds in Eclogite are generally too small to be of economic worth so Eclogite is famous for other reasons. Eclogite is one of the densest rocks known to man – its density is hypothesized to be one of the drivers for plate tectonics. Eclogite forms as basaltic rock is subducted, and exposed to extremely high pressure within the mantle. For an Eclogite to form, the basalt needs to be subducted to a depth of at least 45 km.
