  ‘Ghost’ Plume Found Beneath Oman May Explain India’s Ancient Tectonic Shift

  A buried magma plume beneath Oman’s Salma Plateau may have nudged India’s tectonic path during its collision with Eurasia, scientists report. Named “Dani,” the amagmatic plume caused no eruptions but likely altered continental motion 40 million years ago. This discovery redefines how silent, deep mantle forces can reshape continents without...

  Venus May Be Geologically Active: New Study Reveals Tectonic Processes Shaping Its Surface

  Is Venus still geologically alive? New findings using NASA's Magellan data reveal that the planet's surface may be actively reshaped by subsurface plumes, supporting modern tectonic activity. Using NASA’s Magellan data and computer simulations, the study offers compelling evidence that Venus is not geologically dead, with implications for future ...

  New Study Confirms Venus Is Still Geologically Active

  A new study shows Venus is still geologically active. Scientists discovered mantle plumes creating coronae on their surface, revealing dynamic inner processes similar to early Earth. This breakthrough sets the stage for upcoming NASA and ESA missions to study Venus in greater detail.

  Silent Chernobyl Incident of Aral Sea Caused Earth’s Mantle to Bulge the Land, Study Finds

  The desiccation of the Aral Sea led to the water being divided into two parts. The study reveals that the land beneath the sea is lifting every year, causing the Earth’s mantle to bulge up over the next few years.

  Earth’s Mantle Could Be Harbouring Ocean of Magma Formed Billions of Years Ago, Claims Study

  The study conducted by Boukaré and published on March 26 in the Journal Nature suggests that this molten layer at the core-mantle boundary of the Earth formed the internal thermal structure of the planet and tectonic plates. This may still influence the geochemical process of the Earth today. Further, it suggests a similar magma ocean existence on...

  Part Of North America Is Sinking Into Earth's Mantle: Study

  A chunk of ancient oceanic crust buried deep beneath the Midwest is pulling parts of North America's crust down into the Earth's mantle, scientists have found.

  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...
