Seafloor Spreading Slowdown May Have Caused 26–32m Sea Level Drop Over Millions of Years
Between 15 million and 6 million years ago, ocean crust production declined by 35 percent, leading to deeper ocean basins. This geological shift is believed to have caused a sea level drop of 26–32 meters. Research suggests that heat transfer from the mantle to the ocean decreased by 8 percent, potentially altering ocean chemistry. Some studies i...

Massive Continent-Sized Blobs Deep in Earth’s Mantle May Be Over a Billion Years Old
Massive mantle formations, called LLSVPs, have been found to be over a billion years old. These structures, sitting 3,000 km beneath the surface, slow seismic waves, indicating unique physical and compositional properties. Their stability suggests they influence Earth's geological processes, including volcanic activity and tectonic movements. Scien...

Seismic Data from NASA’s InSight Might Solve the Mystery of Mars’ Dichotomy
NASA’s InSight mission has provided seismic data shedding light on the Martian dichotomy, the split between Mars’ northern lowlands and southern highlands. Findings from the mantle’s seismic wave analysis suggest the split stems from ancient tectonic activity and magma dynamics, rather than asteroid impacts. Variations in crust thickness and ...

Scientists Uncover 'Sunken Worlds' Deep in Earth’s Mantle, Defying Geological Expectations
A new study has uncovered unusual anomalies deep within Earth's mantle, resembling sunken crustal slabs in unexpected locations. Using advanced full-waveform inversion, scientists were able to map these structures, revealing hidden patterns that challenge current geological understanding. These anomalies were discovered far from tectonic activity z...

Did Earth Create the Moon? Research Uncovers Clues About Lunar Formation
Recent findings from the University of Göttingen and the Max Planck Institute challenge previous theories about the moon's formation. The study reveals that the moon was largely created from material ejected from Earth's mantle, not from the protoplanet Theia. Additionally, it offers new perspectives on the origin of water on Earth, suggesting tha...

Scientists Say Earth's Mantle Is Split Into Two Halves. Here's Why
Scientists say that the mantle is split up into two domains- the African and the Pacific that emerged when the supercontinent Pangaea broke apart.

"Major Mystery": Scientists Discover "Sunken Worlds" Under Pacific Ocean
Scientists have discovered potential patches of Earth's ancient crust, sometimes called the "sunken worlds", deep within the mantle, all thanks to a new way of mapping the interior of our planet.

Opinion | The Congress Is Fast Losing Friends
The Congress is under attack as allies mount pressure to hand over the mantle of leadership to another player, unwilling as they are to be led by the Grand Old Party. T

Gold-Sulfur Complex Found to Play Crucial Role in Gold Deposit Formation
An international team of scientists, led by Adam Simon, has uncovered the role of a gold-trisulfur complex in gold deposit formation. The research, published in the Proceedings of the National Academy of Sciences, reveals how this complex forms in the Earth's mantle under specific pressure and temperature conditions, especially in subduction zones ...

Earth’s Inner Core Might Be Slowing Down and Changing Shape, New Study Reveals
Research suggests Earth’s inner core, a metal sphere within the molten outer core, is slowing its spin and reshaping. Seismic wave analyses from earthquakes reveal discrepancies indicating deformation on the core’s surface or changes in rotation. John Vidale, a geophysicist from the University of Southern California, presented these findings, s...

Himalayas Mountain Range Formation Could Have Destroyed 30 Percent of Continental Crust, Says Study
A study published in Earth and Planetary Science Letters has found that up to 30% of Earth's continental crust may have been lost to the mantle during the formation of the Himalayas. Researchers from Monash University used a model to calculate crustal loss, revealing similar patterns in the European Alps and Zagros Mountains. The research highlight...

Indian Ocean Gravity Hole Might Have Been Formed After the Death of an Ancient Ocean
A vast anomaly in the Indian Ocean, called the gravity hole, has been studied for decades due to its weak gravitational pull and significantly lower sea levels. Recent findings link its origins to the ancient Tethys Ocean and mantle changes caused by tectonic plate shifts. Researchers used advanced models to simulate the geological processes, revea...

Geodynamic Mantle-Flow Model Reveals Erosion Process of North China Craton
New research from China University of Geosciences unveils how tectonic shifts eroded the once-stable North China Craton. Led by Professor Shaofeng Liu, this study explores flat-slab subduction processes, revealing three stages of deformation due to the ancient Izanagi plate’s horizontal movement beneath the Eurasian plate. This breakthrough redef...

Earth's Crust is ‘Dripping’ Beneath Turkey’s Konya Basin, Revealing Unique Geological Phenomenon
Researchers have uncovered a remarkable geological phenomenon beneath Türkiye’s Central Anatolian Plateau, where dense materials from Earth’s crust are detaching and sinking into the mantle below. This process, known as multi-stage lithospheric dripping, has been shaping the Konya Basin’s surface and provides crucial insights into Earth’s ...
