Specimen of bright blue cavansite clusters that look like pom poms on a layer of small white crystals on a matrix. It sits on a frosted plinth with Cavansite written twice on it on a glass shelf in front of a grey background. At the Royal Ontario Museum.

Bright blue cavansite!! They look like bright pom poms! #MineralMonday #GeoscienceBluesky ⚒️🧪

A micro mineral specimen of dark blue lustrous Clinoclase forming prismatic crystals on a soft botryoidal green Cornwallite. This specimen comes from Pershing County, Nevada.

Happy #MineralMonday y'all! I bestow upon thee a fine micro specimen of vibrant blue Clinoclase on green botryoidal Cornwallite. Both minerals are copper arsenates so don't lick them!

Metallic grey crystals of Andorite from Romania

#MineralMonday for all !

Nice metallic grey shiny crystals of Andorite, from the type site in Romania.

With Pyrite and Quartz for a perfect combination.

Specimen of polished agate in a thin tabular form showing grey wavy stripes similar to a strip of bacon ima white tray. At the Canadian Museum of Nature.

Grey bacon? Lace? This is agate, a variety of quartz, with beautiful layers. #MineralMonday #GeoscienceBluesky ⚒️🧪

sprays of blue cavansite crystals

Sprays of celestial blue Cavansite for this #MineralMonday

Nice specimen from India, with lovely contrast between blue Cavansite and white albite crystals.

A mineral specimen of blue to purple Fluorite cubes sitting on grey Muscovite with a little bit of orange iron staining. White Quartz crystals are also growing on the Muscovite. This specimen is from China.

Happy #MineralMonday peeps! Today I got an oldie from my collection, purple and blue Fluorite cubes on Muscovite with Quartz.

Morning on Ynys Môn:

Cinnabar - Epic Mineral Overview Cinnabar is bright red mercury sulfide, main ore of mercury and a source of red pigments.

Infamous #Cinnabar is well known for its toxicity. It is the only source of mercury, which is important for numerous industrial applications.

A #FridayFold of kinked, crenulated phyllite that I saw yesterday while poking around at the Virginia state geologic survey. ⚒️

Specimen on mounted on a green background below a title that says FOLDING. The specimen is brown and is a zig zag with the high hump on the left labeled ANTICLINE and the low bump to its right labeled SYNCLINE. The label below says: ANTICLINAL AND SYNCLINAL FOLDS IN QUARTZITE BOULDER CO., COLORADO At the Field Museum.

Love this old fold exhibit showing this gorgeous example of a anticline and a syncline. The oldest rock layers are on the bottom which helps identify the type of fold. These formed from pressure caused by compression. #FridayFold #GeoscienceBluesky ⚒️🧪

intense green micro crystals of conichalcite

Green #MineralMonday with an intense flashy green conichalcite from Greece (Lavrion of course).

Named from greek konis (dust) et khalkos (copper), belongs to a serie with last week Duftite.

Native Platinum - Properties, Photos and Occurence Platinum is a valuable precious metal native element, prized for its physical resistance to chemical and temperature assault.

Native #Platinum is a very rare metal and critical industrial material. It has extreme physical properties, which are important for modern applications. Yet, platinum is very scarce.

Specimen of labradorite that shows patches of bright blue, yellow green, and brown on the front surface. The sides are grey. It sits on a grey plinth on a grey background. A small frosted plastic label says Anorthite Anorthite on the lower left. At the Royal Ontario Museum.

Gorgeous technicolour labradorite!! This labradorescence shows a range of colours across the labradorite, a variety of feldspar that is primarily the mineral anorthite. #MineralMonday #GeoscienceBluesky ⚒️🧪

A mineral specimen of a small geode with white Calcite and golden needles of Millerite in the cavity.

Y'all know what today is! It's #MineralMonday! Today I have a funky little geode with golden needles of Millerite (NiS) inside!

⚒️ #geology

An outcrop of gray green rock, with some orange staining, cross cut by numerous white veins of quartz, but the veins are very short and stubby. The shape of the veins is kind of like an elongated S. A rock hammer provides a sense of scale.
