Scientists have discovered two massive structures beneath Africa and the Pacific, known as LLSVPs, which may be remnants of the ancient planet Theia that collided with Earth billions of years ago, potentially influencing Earth's geological activity and surface features.
A study suggests a massive hot rock formation called the Northern Appalachian Anomaly is moving towards New York City from deep beneath the Earth's crust, potentially explaining aspects of Earth's geological history and continental movement, but it won't reach NYC for another 15 trillion years.
China is drilling a 6-mile-deep borehole in the Taklimakan Desert to study Earth's crust, tectonics, and ancient geological records, pushing the limits of drilling technology and expanding understanding of Earth's interior.
Scientists have discovered evidence suggesting that Earth's lower mantle may contain a massive, hidden water reservoir, potentially larger than all surface oceans combined, stored within mineral structures like bridgmanite, which could significantly impact our understanding of Earth's water cycle, planetary formation, and geological processes.
A new study suggests that the two massive structures beneath Earth's surface, known as LLSVPs, are remnants of the planet's early magma ocean, formed by chemical interactions with the core during Earth's formation, which could reshape our understanding of Earth's deep interior and its habitability.
Scientists have uncovered new insights into the Indian Ocean Geoid Low, the largest gravity hole on Earth, linking it to mantle processes such as sinking slabs and rising plumes originating from deep within Earth's mantle, which have evolved over millions of years and are influenced by interactions with the African hotspot and mantle structures like the LLSVP.
Scientists have identified the cause of the Indian Ocean Geoid Low, a large gravity anomaly, as deep mantle processes involving ancient subducted slabs and buoyant plumes beneath Africa, which have reshaped Earth's gravity field over the past 20 million years.
Researchers analyzing data from the GRACE satellites discovered a mysterious gravity signal off the coast of Africa that lasted for about two years, likely caused by a previously unknown geological process involving a phase transformation in Earth's lower mantle, revealing the planet's complex internal dynamics.
Scientists analyzing data from NASA's GRACE satellites discovered evidence of a massive shift deep within the Earth's interior near the core-mantle boundary, possibly caused by changes in mantle minerals like perovskite, which may have influenced Earth's magnetic field and caused a geomagnetic jerk around 2007. They plan to use data from the follow-up GRACE-FO mission to further investigate these deep Earth processes.
Researchers using NASA's GRACE data discovered a 7,000 km gravity anomaly over the Atlantic, potentially linked to a 'geomagnetic jerk' caused by rapid mass redistributions deep within Earth's mantle, possibly at the core-mantle boundary, indicating complex interactions between Earth's interior and magnetic field.
Satellites have revealed mysterious changes near Earth's core, suggesting a transformation in deep underground rocks that may be causing the core to leak, providing new insights into Earth's internal structure and its effects on seismic activity and magnetic field.
A large, hot rock anomaly beneath New Hampshire, called the Northern Appalachian Anomaly, may explain the uplift and stability of the Appalachian Mountains and is moving towards New York over the next 15 million years, offering new insights into Earth's deep geological processes.
A hot rock blob beneath New Hampshire, called the Northern Appalachian Anomaly, may explain the uplift of the Appalachian Mountains and is linked to ancient continental rifting, with its movement predicted to reach New York in 15 million years. This thermal anomaly, formed from mantle processes related to past tectonic events, influences Earth's surface features and deep geological activity.
Geologists have discovered massive, ancient 'fortresses' in the Earth's mantle, located 1,800 miles below the surface, challenging traditional models of mantle convection and offering new insights into Earth's internal dynamics and geological processes.
Recent research reveals that mysterious structures called BLOBS in Earth's lower mantle are linked to volcanic eruptions, acting as 'magma highways' that influence mantle plumes and potentially trigger catastrophic eruptions, with these structures possibly shifting over time due to mantle convection.
