Some volcanic rocks carry hydrogen signatures that may trace back to Earth’s metallic core. Lavas from Baffin Island in the Canadian Arctic and Iceland contain unusually little deuterium, hydrogen’s heavier stable isotope. Explaining that imbalance could reveal whether the core has supplied material to the mantle over billions of years.

Work led by Wenzhong Wang at the University of Science and Technology of China tests a competing explanation. Published in Science Advances, the study examines whether crystallization of Earth’s ancient magma ocean could have created those distinctive signatures. Its simulations indicate that this process produced far too little separation between hydrogen isotopes.

The result strengthens the argument for selective transfer of hydrogen from the core into the surrounding rocky mantle. It does not directly demonstrate leakage or establish how quickly it occurs. Instead, the calculations constrain what an important alternative mechanism could have accomplished.

Hey,

I've just made a new YouTube Video about Cyanobacteria, and the Great Oxidation Event, don't hesitate to check it out if you're interested, and tell me what you think !

Have a Great Day !

When checking by depth, using formulas like for how density and the y-value pressure increase linearly to each other, gravity is with a −2nd exponent problem shifted by ~4*10^14 and ~6 million, conditions that change, and even a few of the other variables control others, the pressure is higher. When searched about, it gave around 1104 atmospheres, or 1119-ish bar. Even when dividing by 10 +1 type of stuff, even though it is not as high as the more precise formula, it is still more than the given pressure, 1071.799 atmsopheres, 1086 divided by 1.01325. When searched about, some details say that it was from a 35814 feet (from an older review, now less than the actual depth) divide by 33 +1 calculation, gave 1086 atmospheres, and was eventually given as bar somewhere along the way and made its way to Wikipedia. There might still be less precision, but i wonder what really is the case.

Hi everyone,

The Anatolian Microplate is one of the most dynamic seismic zones in the Mediterranean region. Its tectonic framework is largely defined by two major transform boundaries:

* North Anatolian Fault Zone (NAFZ): A right-lateral strike-slip system traversing northern Turkey, accommodating the westward movement of the Anatolian block.

* East Anatolian Fault Zone (EAFZ): A left-lateral strike-slip zone formed by the collision between the Arabian and Eurasian plates.

Understanding these fault mechanics is essential for assessing regional seismic hazards. Looking forward to discussing earth science perspectives on this area!
