Truly rare to find this large a piece of crystalline, faceted leucite

Gem Properties as Personality Traits:

Okay, so one of the reasons I love Steven Universe is because even when I was really little I loved Gemology (a specific branch of geology dealing with gemstones and whatnot), I had a friend whose parents were professional gemologists and were contracted by big jewelry firms and they were always showing off rare and unique specimens because they knew how interesting gems could be. They showed me a lot of rare stones, how to get some of them, and there were always some rocks in little biohazard boxes and with weird symbols on their containers, and I always wondered why they wouldn’t take those ones out to show us them, even though some of them were really really pretty.

Anyway, fast forward to modern day and I’m going through my usual sources for unique gems when I realize there’s a whole category of gemstones that would be ridiculously interesting to look into: Radioactive Gems.

I don’t mean Uranium or Plutonium, etc. Those are elements taken by purifying minerals. I mean actual gems that contain radioactive minerals and/or have radioactive properties.

There’s already been one on the show, actually, but not a very strongly radioactive gem. Sugilite contains a large amount of potassium (which is surprisingly a mildly radioactive element) and is categorized as a Barely Radioactive Gem.

Radioactive Gems (with radioactivity strength included: Barely, Mild, Weak, Strong, Very Strong) include, but are not limited to:
-Adularia (Barely)
-Aeschynite (Weak)
-Afghanite (Barely)
-Ajoite (Barely)
-Allanite (Weak)
-Alum (Barely)
-Alunite (Barely)
-Amazonite (Barely)
-Apophyllite (Barely)
-Arrojadite (Barely)
-Astrophyllite (Barely)
-Autunite (Very Strong)
-Barrerite (Barely)
-Bastnäsite (Weak)
-Betafite (Very Strong)
-Boleite (Barely)
-Burbankite (Mild)
-Casanite (Barely)
-Celadonite (Barely)
-Chabazite (Barely)
-Charoite (Barely)
-Coffinite (Very Strong)
-Cuproskludowskite (Very Strong)
-Ekanite (Strong)
-Eudialyte (Mild)
-Euxenite (Mild)
-Fergusonite (Weak)
-Fluorobritholite (Weak)
-Fluoro-Postassichastingsite (Barely)
-Gadolinite (Weak)
-Ganophyllite (Barely)

-Mariposite (Barely)
-Meta-Autunite (Very Strong)
-Milarite (Barely)
-Monazite (Weak)
-Mordenite (Barely)

-Poudretteite (Barely)
-Rémondite (Weak)
-Rhodizite (Barely)
-Samarskite (Very Strong)
-Sanidine (Barely)
-Soddyite (Very Strong)
-Sogdianite (Barely)
-Steacyite (Strong)
-Syngenite (Barely)

-Titanite (Mild)
-Vandenbrandeite (Very Strong)
-Yttrocrasite (Strong)
-Yuksporite (Barely)

Are more radioactive gems like Coffinite, Thorite, and Thorianite (each of which has 70-90% raw uranium in their chemical buildup) even more monstrous? Or instead of being monstrous physically are they more erratic? Do they decay over time? Are they toxic in personality? Does prolonged exposure to Gems with these as their Gem cause people to get sick and die? Does being around them affect the color and properties of Gems around them? (Irradiation is a common way to change the color and luster of many gems).

What if Rose had sympathy for these Gems, like a Thorite that has to hide out in the wastelands of the Russian Tundra, or a small community of them living in the area affected by the Chernobyl fallout?

What if they loved Earth enough to fight for it, even though they are just as bad for the earth?

Stage 2: Cap de Creus to Olot, Volcanism of the Quaternary la Garrotxa Volcanic Field

Here is what I imagine the volcanoes to look like:

Here is what I actually saw:

After the unexpected but not surprising hike, the volcanoes were kind of disappointing. 

Anyway…

The La Garrotxa Volcanic Field forms part of the Catalan Volcanic Zone (north-east Iberian Peninsula), one of the alkaline volcanic provinces of the European rift system. It harbors more than 50 basaltic monogenetic cones that range in age from Middle Pleistocene to the Early Holocene. The Garrotxa Volcanic Fields is made up of cinder and scoria cones, lava flows, tuff rings and maars. The volcanic products are strongly silica-undersaturated to nearly silica-saturated compositions: leucite, basanites, nepheline basanites and alkali olivine basalts. Eruption sequences differ from one cone to another and did not follow a common eruption pattern. The complex eruptive behavior may be related to the differing stratigraphic, structural and hydrogeological characteristics of the substrate below each volcano rather than to any differences in the physicochemistry of the erupting magmas, which are fairly homogeneous throughout the Garrotxa Volcanic Field.

Tectonically, the cones formed between two normal faults, the Amer and Lloria. My professor laughed at the geophysicists that studied the volcanic field because of this picture: 

My professor says the question marks throughout the cross section is a good example on why geophysicist is mostly arm waving (which it is not true). 

After Day 3, my feet had some nice blisters. Stage 3 was driving on our lovely stinky bus to the next hostel in Sort, Lleida.
