New Fossil found! 😂

My kind of fireworks? Volcanic lightning. Who needs sparklers when magma’s got a built-in light show? #HappyNewYear #Geology

Earth recycles oceanic crust through subduction. We recycle New Year’s resolutions. Nature’s got us beat. #HappyNewYear #Geology

Orogeny (mountain building) takes millions of years, but we expect instant changes after the clock strikes midnight. Perspective, right? Let 2025 be the start of something awesome. #HappyNewYear #Geology

As one year settles like a new sediment layer, the next awaits discovery. Wishing you an awesome 2025—Happy New Year! #Geology

Why does this matter to you today? Because the stones in Rome’s buildings shaped how structures were designed, how big they could get, and even how they withstood earthquakes and erosion. Without the right geology, would Rome’s grandeur have survived centuries of history?

Marble, often imported from regions across the empire, polished Rome’s image. While not always local, it still matters geologically. Roman roads and trade routes tapped into distant marble sources, bringing metamorphic masterpieces into a city founded on sedimentary and volcanic stone.

Volcanic tuff is another Roman favorite. This porous, lightweight rock formed from volcanic ash deposits. Ancient builders used it for walls, foundations, and core structures. It’s no accident Rome thrived in the shadow of volcanic regions—geology offered a literal building block.

Travertine, a light-colored, banded limestone, is Rome’s celebrity stone. It’s what gives the Colosseum its warm hue. Quarried near Tivoli, this stone is strong and relatively easy to shape, making it perfect for colossal architecture that has stood for nearly two millennia.

We often think about Rome’s power—military conquests, cultural achievements, political might—but do we ever consider the rocks under its sandals? The city’s legendary structures owe much of their existence to specific stones pulled from local quarries and volcanic fields. #Geology

On April 1st, 1974, a man hauled 70 tires up to the mouth of a dormant volcanoe in Alaska and set them alight. Seeing the smoke, the residents were afraid that the volcano was about to erupt and called the police. When they investigated, "APRIL FOOL" was spray-painted next to the tires. #Geology

The deep ocean isn’t a place we fully understand. It’s easy to say, “We need metals, let’s take them,” but what about the life down there? They’ve evolved for eons in total darkness. Nodules and their ecosystems took millennia to develop, and we’re not sure how resilient they really are.

Metal demand keeps rising, and nodules look tempting. They lie in places like the Clarion-Clipperton Zone, loaded with metals we need. But mining them with giant machines could cloud sediment, smothering mysterious deep-sea creatures we barely know.

A nodule is a dark, knobby lump a few centimeters wide, holding nickel, cobalt, manganese, and copper. These metals power phones, laptops, and EV batteries. Nodules grow painfully slow, layer by layer, so slowly that a human lifetime shows no visible change.

You ever picture the ocean floor as a quiet, empty plain? Down there, scattered like odd potatoes, lie polymetallic nodules. They’re metal-rich lumps on muddy sediments, sometimes miles deep, forming over millions of years, layer by careful layer. Let's explore 👇 #Geology

Magnificent photos by photographer Daniel Kordan of Mount Bokty in Kazakhstan 🇰🇿 #Geology Its a lovely sedimentary sequence that has been eroded to the point that this is the last of the caprock (flat unit on the peak) to be weathered away.

A tiny diamond inclusion revealed a grand planetary truth. Each fragment from deep below is a postcard from Earth’s inner workings, proving we still have much to learn about our own home.

If Earth has water-rich depths, maybe other planets do too. Hidden interiors may be common in the universe, guiding us in the search for life. Our planet’s secret could be a cosmic clue.

This hidden ocean might be key to Earth’s stability. It helps recycle volatiles, influencing climate over geologic times. Without it, our world might look very different—less dynamic, less life-friendly.

Experimental data shows ringwoodite can store loads of H₂O. Seismic studies hint at “wet” zones. Diamonds prove it’s real, not theory. Confidence: ~99% ringwoodite can hold water, ~95% it shapes deep Earth processes.

Water lowers the melting point of rocks. More water = easier melting, fueling volcanic activity. Deep water moves in and out through subduction and volcanism, quietly tuning Earth’s climate and surface environments.

Why care? This hidden water influences volcanic eruptions, tectonics, even long-term climate. Earth’s deep water cycle affects how continents form, how mountains rise, and how life’s stage is set over eons.

In 2014, scientists found ringwoodite in a diamond from deep inside Earth. It held ~1% water by weight. If much of the mantle’s transition zone is similar, we’re talking a colossal secret reservoir beneath our feet.

Buried deep below Earth’s crust, a hidden “ocean” may exist—water locked in ringwoodite within the mantle. Imagine vast H₂O reserves rivaling all surface oceans combined, tucked hundreds of kilometers down. Mind-blowing, right? Let's explore 👇 #Geology

Curious about this purple opal? Or is it blue? It seems like the color can look different depending on who's looking - what do you see? #Geology
