Today I am in . The decision wasn't so easy but I figured out that a variety exists that is called & that sodalite shows CAThodoluminescence & my favorite blanket is blue

I voted for because of its awesome significance for humankind throughout the ages, but I do like seeing in building stones. This photo is from the front of a Deutsche Bank in Berlin.

Here is my lapis lazuli dice set from @urwizards along with a necklace I made using rhodochrosite, jade, and lapis lazuli beads. Lazurite, the blue mineral in the lapis is a member of the group.

aletamosquito,

Here's a better lit, closer in view. I don't know why I could not put both photos in one toot.

Today's vote is based on my , Lapisbee the druid gnome. Lazurite, the blue mineral in lapis lazuli is a member of the group. Blue beats sparkly this time.

It’s a difficult decision for todays . I love blue minerals of all sorts, but I also love ore minerals. In the end, I chose the antimony ore over simply for the fact that I had fun collecting once

is one of over 400 mineral type found in a quarry at Mont Saint-Hilaire, east of , where an alkali-rich mafic magma intruded carbonates.

The Mineralogical Association of Canada has published a beautiful book on this locality (2nd ed. out later this year):

@FaithfullJohn is just one of several blue minerals in -get used to it! Better than stibnite swords of death.

vs . Both excellent minerals, but I'm going for sleek metallic stibnite. It's a much more beautiful word to me, and it contains the also-excellently named element, antimony. Here's a wonderful specimen of stibnite (about 25cm across!) in the collections of the Hunterian museum, from the Sovacon mine, in Bolivia, which in the early 1980s produced a bonanza of great specimens.🥰 😊

@Okanogen@mastodon.social avatar

Okay, vs . Stibnite is cool, but I have to be in this matchup. I've always been fascinated by sodalite and all of the related minerals that only occur in very special silica poor or absent melts. They are like the kicking ass over the (and I already championed as the Yankees). Plus, sodalite is an awesome blue color and flourescent under UV. How cool is that!!!!????

Okanogen,
@Okanogen@mastodon.social avatar

So, what does it take to be a silica deficient magma like those that produce ? Well, the entire earth is 32%Fe, 30%O, 15%Si & it drops off quick. But the crust is 47%O, 28%Si, 8%Al, 5%Fe. You need to remove that 28% for rock so the source material itself must be silica deprived. Magmas created from quartz-poor sources include deep marine subduction zones where ocean floor sediments are clayey, calcareous, high in AL but also low in silica, which is rare!

Okanogen,
@Okanogen@mastodon.social avatar

Now the cool thing about is that yes, there will be a sizeable proportion of silica containing alkali feldspar. , and others, if present, crystallize AFTER the available Si is used up. So they may be vein-filling or adjacent in the matrix. But if they are present, that's definitive for a silica poor source magma. Anyway, VOTE SODALITE!

MicrotoPico, to random German

Today its dreamy blue against the antimony ore in I am still undecided...

MicrotoPico,

is a dark blue or sometimes white or yellow mineral belonging to the alumosilicates. It is sometimes used as a gemstone, but not as a pigment, because its streak color is white.

inoru_no_hoshi, to random

So I had to go remind myself what is because frankly I'm more used to seeing "antimony" still, but...

as much as is fun and pretty... listen, it's not chaos. Stibnite is basically chaos in most of its historical uses, iirc!

Also it often co-occurs with things like , , , and ... now that's some fun chaos company. Vote Stibnite for chaos!!
