Looked at the European Cenozoic Volcanic Province:
Petrology of silica undersaturated rocks,
olivine-melilite-nephelinite and other tongue twister
& Geochemistry of (trachy-) basalts to trachytes
Now metamorphic MIs

Normally I'm a sucker for rare element and rare earth element minerals, but this round has to go to Titanite.
And not just because they appeared in my hand-grinded thinsection of some tephrite feom the Kaiserstuhl volcanic complex 👀

Few minerals need their own cabinet to display all their different shapes!

One of the main reason to vote for both are exotic melts, undersaturated or devoid of SiO2. Like this carbonatite from the Kaiserstuhl volcanic complex I made into a big thinsection!

Vote Haüyne,
vote for its blueauty, vote for the only Umlaut in the cup,
vote for its sulfur content, vote for the largest eruption on continental europe in the past 15.000 years this Eifel specimen originated from.

Not at all an ominous mirroring of this first round how in the geologic collection of Göttingen this Pectolite sits right above Chrysotile... 👀

Hab gerade leider nur ein Beispiel zur Hand. Wenige hundert Meter war eine Landstraße.
Es ist kein rein negativer Impakt. Und man muss einfach ehrlich sein, dass Forst eben nicht gleich Wald ist.

Wish I had better gear and experience back then. But at least I got it one time early in the morning with noctilucent clouds.

Vor einem Ausbruch wird sich der Boden noch deutlich mehr heben.
Bei dem jetzigen Tempo dauert es noch Jahrzehnte bis zum Monte Nuovo Niveau. Es hat sich auf alle Fälle nicht genug eruptives Magma angesammelt um nur im entferntesten eine große VEI 7 Eruption zu verursachen.

For #ThinSectionThursday I present my very first self made thinsection of an hornblende amphibolite from the austrian alps!
I made it on a large 10x7.5cm glass plate to preserve its natural shape.

Finally did what I wanted for many years studying geoscience: Making my own thinsection(s).
For some time I already had a slab of amphibolite prepared but not an appropriate sized glass plate. Now I could go to work with my grinding and polishing powder because I did it all by hand.

Context where this earthquake swarm is occuring:
Almost every week there are notable earthquake swarms occuring in western Iceland.
Depth range from 16-17 km - 1.1 km.
Movement is happening along the entire column of the crust here.
A much larger EQ could create a path for magma to the surface, similiar to before the Fagradallsfjall '21 eruption.

Interesting earthquake swarm going on at the eastern end of the Snæfellsnes peninsula, 70km north of Reykjavik.

The main earthquake activity is still ongoing and to the north of the fissure opening. Worth having an eye on.

Eruption started near Grindavik east of Hagafell. Roughly where a shallow aseismic zone could be made out in the depth vs. long/lat data.

Quick and dirty diagrams of the ongoing earthquake swarm on the reykjanes peninsula for today.
A lot show up at exactly 1.1 km depth, which I guess is an automated, not accurate estimate. Depth vs. time shows EQ getting deeper and shallower since the start of the intrusion. This is an ongoing event

For #astrophotography I mostly focus on brighter object or reflection nebula since they are more easily picked up by my standard, non-modified Canon 700D.
Last week I tried myself on NGC2174, a hydrogen emission nebula. The bicoloration is still clearly visible.

M 101 (the pinhole galaxy) is one of the largest visible galaxies next to the Andromeda, Triangulum and Bodes galaxy.
Unlike the latter it faces us head on, so it appears a bit larger, despite being twice as far away (but it's also twice as big).
280 minutes of 300s sub-exposures.
