Any idea what this may be. Found in a rock pool in WA

As a fan of #geology and LGBT I really enjoy this #meme

😆😆

Wall outcrop. Sedimentary rock. Lamination.

One of (those) Field Day. Kinda miss it #geology #adventure

Crossing the meandering river (and its bank). Central Java, Indonesia. Beautiful sunny day 🌞 #adventure

My collection

Rare, water soluable uranium ore. This time my specimen is incredibly small, so had to take a macro, probably the rarest mineral currently in my collection. It's from Recsk, Hungary

☢️Andersonite☢️

Any idea? Non magnetic. Found in rock pool. On abandoned island.

Titanium-dioxide, the most common natural form of it. It's properties very useful for manufacture of certain optical elements (polarization optics). Rutile is common accessory mineral both in igneous and metamorpic rocks this type of the crystals is actually common in other crystals (quartz for example), but not that common in this form, because it's very fragile, which making it incredibly rare.

Rutile

The Mohs scale

Also, what did the emrald say to the graphite? You rock!

I've had a weird obsession with Obsidian since I saw that one guys on YouTube make spears and arrowheads out of Obsidian with... Obsidian.

Honorary mention to Amber, it's not a rock but it's so effing cool.

What's your favourite rock and why?

It wasn’t their fault, there was just too much friction between them.


I saw it. I had to share it, so here it is. Sue me.

Why did the tectonic plates break up?

Fossilized wood that my grandfather gave me a few months ago. It's been sitting on my dresser since October so it's dusty af. My grandfather found it in either a creek bed or old river bed decades ago. I'll have to ask him again I can't remember which.

Fossilized Wood

I've just recently moved here and now the moves complete, does anyone know any interesting geological facts about Northumberland. Or suggestions of where to go.Anyone fancy getting hammered and seeing if we can get our rocks off?

North East England

I'm not sure what kind of geode this is. Had it for a while. Any ideas?

Geode

The picture can't giving back it's starry shine, mined in Morocco and it's common. The good quality ones and the geodes are rare and usually small, the tabled crystal form is the most prized. A piece of the Starry Sky, crafted by Mother Earth.

Gift from the Copper mine: Azurite

Illustration for better understanding

That lava flow frozen in time...

It is from my collection, and it kept all the time in that plastic container due the alpha radiation. It's used worldwide as dense uranium, pressed into yellowish "cakes". Mined in 2021, France. It can be found within other copper ores.

Rare gems: Torbernite

Calcite var. Hungary- Pilisjászfalu, collected by Zoltán Urbán in 2019, bought it, and added to my collection in the same year. It begun to dissolve back, that's why it's dull surface, Mt. Pilis is famous here from it's karst cave system, it's stalactites mainly from this calcite.

Collection

Something really common, but really beautiful. It's the most frequently mined ore (galena) in the Carpathians along with the iron, copper and aluminum ores. This specimen is probably from Romania or Slovakia (I haven't got a label, but it's price said that). Not my rarest, but one of the best specimen in my collection.

Quartz-Pyrite-Galena on matrix

This one is Spessartine Garnet with Quartz and some metamorph crystals from China. The Garnets are widely used since the Bronze age as abrasives and jewelry and  it's color varies from the burgundy and tea color to green and even blue (which is very rare).

Rare gems: Garnet (it's not that rare at all, but still precious)

Noble beryl from Shigar valley, Pakistan.

Rare gems: Aquamarine

Actually an abundant rock forming stone, coming along with marble. It's color depends on the iron content. Sometimes the well formed crystals used as gemstones, which is very rare. This one mined in Italy.

Rare gems: Epidote

I posted this azurite a while ago, so I'm not going to do a bigger description about it, but now I can show  it's real beauty thanks to the video posting.

Azurite repost

It's an Iron-Phosphate, which origin can be both igneous and as it's name says in the proper conditions growing from the iron content of a dead body in phosphorus-rich environments. It's color is originally dark bottle green or dark blue, and it's very fragile 1,5-2 it's hardness on the Mohs- scale.

Vivianite, the Corpse Crystal

Labradorite labradorising.  The Labradorite is a calcium-enriched feldspar which can display an iridescent effect. This one is mined in China, but can be found in Canada (Where it's found for the first time and got it's name from), Madagascar, US, Australia and Slovakia. It's iridescence can come in various colors, some of them are rare, like the peacock blue, the pink or the purple. Very popular stone amongst the collectors and jewellers too. Also a rare occasion of keeping cabochons in my collection.

Rare gems, polished edition (and it's not rare either)

As seen at DMNS from the Sweet Alma mine here in Colorado

Rhodochrosite

It's the famous Silicon (Si) in it's metallic form. You can't find this form in the nature, people synthetising it from quartz sand usually. The most abundant metal on Earth, and the theoretical building block of the non-carbon based life on other planets somewhere in the Universe.

The fake metallic "twin" of the Carbon

More likely #paleontology, since it's a basilosaurus molar, but really a decent one so I think it having place here too.

More of the collection

A single Fluorite on Quartz matrix

CaSO⁴2H²O, this mineral have 4 varieties like the Selenite, Satin spar, Desert rose and the Gypsum flower (I have all varieties in my collection). It's very soft even the fingernail can scratch it (2 on the Mohs scale). The Satin Spar variant is often used as cabochons, and esotheric tools, ornaments and carvings. Some of the biggest crystal ever found are also Selenite (Naica Mine, Cave of the Crystals, 12metres long and weighing 55 tons, there is an online documentary about the cave, it's really interesting!)

Probably the most popular crystal: Selenite/Gypsum

Botryodial (typical) form with some Malachite. Mined in Katanga, Congo. It's name reflecting it's use, which is soldering gold. It's a secondary origin copper ore, and used also as a semi precious stone.

Gift from the Copper mine: Chrysocolla

One of the best of my collection, mined in Wagholi, India.

Cavansite on Stilbite matrix

MgAl²O⁴, mined in Italy, came from the mines of the beautiful Vesuvius.

Rare gems: Spinel, crimson color var.

Chrysoberyl sixling, it having tiny black tourmaline inclusions, and a bit fractured but still a beautiful piece of my collection. Size cc 1cm, mined in Brazil.

Just...

Nature can refer to the general realm of living plants and animals, and in some cases to the processes associated with inanimate objects—the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth.♥️💯
