Did you know there are 20,000 types of rocks on our planet? See how they are classified with our paper models of the #RockCycle, #Igneous, #Sedimentary & #Metamorphic Rocks & #Minerals too! Details here: buff.ly/Rua05Ah

Of the #rocks I’ve collected, it is one of my favorites. I like to use it to confuse students and professors alike. It is a Quaternary finely laminated rhyolite from southwestern Utah. This top view shows bubbles frozen in the rock.

This striking rock is none other than obsidian, which forms when lava cools rapidly with high silica content. This results in no crystals forming, giving obsidian its characteristic glassy appearance.

This thin section image shows augite in a dolerite specimen from Auvergne, France. Augite is a common mineral in mafic igneous rocks.

In this ghostly black and white image we see a field of rounded, bulbous extrusive lava creating a barren terrain. The lava field carries on into the distance, with a ghostly mountain range appearing across the top of the frame. The washed-out sky is featureless.

Luxullianite is a rare porphyritic granite, with striking clusters of acicular tourmaline #crystals. This rock is named after the Luxulyan village of Cornwall, where this specimen was found!

A photograph of a slab of the rock komatiite. The slab is green in color with dark green lines across the front. It is shown on a black background.
Every day is #RockinTuesday if you love rocks enough. This slab of #komatiite, a rare igneous rock, is an excellent example of #spinifex texture. Personal collection; photograph my own.

Basalt is one of the most well-known and common igneous rocks. Did you know that basalt comprises more than 90% of volcanic rocks on Earth?

This lantern slide shows a photograph by Tempest Anderson! Can you guess which active Italian #volcano is captured here? It famously erupted in 79 AD, burying nearby towns such as Pompeii and Herculaneum with #ash and #pyroclastic flows.

Saussurite is formed through hydrothermal alteration of plagioclase feldspar, though it is not a true #mineral as it is a mixture of several others, such as zoisite, epidote, and albite!

Can anyone suggest why this gabbro may look like a barcode? 🔬

Old field geology photo.
Can you guess the type of rock this is?
Hint: It’s Igneous

Rhyolite is an extrusive #igneous rock formed when a silica-rich #magma is pushed out of a #volcanic vent and quickly cools on the planet's surface!

1/2 Some more lovely #igneous #geology this time on Easdale, home of the World Stone Skimming Championships. Although famed for its #slate the upstanding spine of the island is dominated by resistant igneous #dykes , one of which is exposed in 3D with associated spheroidal weathering
It's a trap! This term refers to any dark, fine, non-granitic #igneous rock. This specimen shows amygdales, which are vesicles containing secondary #minerals, and was from Tavistock in England!

Balls of pyroclastic tuff from the Coso Range in California. These unusual and rare spheres were created when a volcanic vent’s lateral explosion sent pumice, tuff, and ash rolling along the ground. Personal collection, my photo.

#geology #igneous It looks like a wall and it functions as a wall - but I is another one of the spectacular Paleogene dykes on the island of Seil in Scotland. This one can be traced from the cliff (behind photo) and out to sea across the raised beach
Fish-shaped biotite aggregate
Calling out the #igneous petrologists out there for help!
This rock is a meta #granite (emplaced and rapidly deformed), and I am looking for igneous and #metamorphic structures.
What is this? It looks like a fish-shaped biotite aggregate. Is it a described/known structure of some sort?

Svartifoss, in Iceland’s Vatnajökull National Park, tumbles over striking basalt columns. In fall, vibrant foliage frames the dark rock, creating a stunning contrast of color and texture. Taken in a long exposure, the waterfall appears as a frozen mist, and the river that flows from it appears smooth almost as if iced over.
