The most common minerals on Earth encompass a wide variety of geological environments and include quartz, feldspar (both potassium and plagioclase varieties), mica (like muscovite and biotite), calcite, dolomite, olivine, pyroxene, amphibole (

A thin section is about as flat as you can get, but put enough feldspar next to each other and it can feel a bit like falling into your microscope. Some lovely diabase today!

This new rock line is based off of the discontinuous series of the Bowen's Reaction Series. The Bowen's Reaction Series is a chart of the different kinds of minerals one can expect from basaltic magma cooling down in different temperatures. The discontinuous series in there describes a progression where silicate minerals crystallize in different patterns dependent on the cooling temperature. If the cooling temperature is still pretty high, the silicate are spaced apart, but if the cooling temperature is much colder, they can join into a sheet. Also btw, silicates aren't triangular but rather tetrahedral (triangle pyramid).

Oligem (Rock): Surprisingly, the crystal part of an Oligem is usually warm to the touch unlike the rest of their body. They sometimes join their legs together like a ring to concentrate and make their crystal glow temporarily.

Petroxene (Rock): Petroxenes appear to like hugging warm bodies as they are much cooler to the touch than Oligems are. When Petroxenes lose chunks of their arms, they can grow them back, but the new arms are shaped differently.

Bienite (Rock): Bienite's joints can regularly bend because, up close, they joints are connected by thin overlapping sheets. Unlike that of their previous stages, Bienite bodies do not leave any heat signatures.

Can you speak about your best rock?

Can I only pick one haha.

Please ignore the pillow I’ve put them on for these photos lmao.

I actually don’t have most of them with me at the moment, but I have a really nice piece of granite with beautiful feldspar macrocrysts which is pretty.

I have some loose pyroxene macrocrysts.

I think my favourite might be these though. They’re fragments from a scoria cone, with small vesicles and glassy iridescent textures too. They’re so pretty.

Look how pretty they are. I guess for now these might by my favourite rocks. At the moment.

My favourite rock that I’ve seen but don’t have is a volcanic bomb with a feldspathoid sodalite in it which I do have a photo of, but no samples. :-(

Mineral themed superheroes! had this idea in lab today and made all of them in one night because i have no regard for the health of my joints.

in order, we have:

Olivine, the loner vigilante who’s cursed so that every time she uses her powers, the iddingsite markings on her arms grow a little bigger

Pyroxene, the spunky skater with a penchant for chain-based weaponry

Albite, the rough and tumble hero who can be in two places at once with the ability to clone herself into duplicates

Quartz, their invincible leader, a sturdy fighter resistent to weathering and with no clear planes of weakness

and Calcite, the heart of their team and the only non-silicate, an optimistic hero with the ability to control light!

First page(s) of the reboot! ^u^ If all goes to plan, this comic will update every Saturday from here on out!
