Satellite data and seismic evidence confirm a multi‑stage lithospheric dripping beneath Türkiye’s Central Anatolian Plateau: unusually dense lower lithosphere sinks into the mantle, deepening the Konya Basin, and later detaches allowing surface rebound as the weight is shed, linking deep Earth processes to observed subsidence amid plateau uplift.
New research indicates that during Earth's early molten phase, vast amounts of water were stored deep within the mantle, particularly in the mineral bridgmanite, which acted as a microscopic water reservoir. This hidden water played a crucial role in Earth's evolution, helping it transition from a fiery planet to a habitable world by facilitating internal circulation and surface water formation.
Scientists propose that a 'glass ceiling' in Venus' mantle traps heat and causes slow, shifting currents, which may explain the planet's mysterious crown-shaped coronae, by creating a reservoir of warm, non-melting material that influences surface features.
Scientists discovered two diamonds from South Africa containing contrasting inclusions that reveal new insights into deep Earth chemistry, showing that oxidized and reduced materials can coexist at depths of 280-470 km, challenging previous assumptions about mantle oxidation states.
Scientists have challenged the long-held theory that the Himalayas are supported solely by a doubled crust beneath the mountain range. New research indicates that a layer of mantle material, sandwiched between the crusts of the Indian and Asian plates, provides the necessary buoyancy and strength to sustain the Himalayas' height, reshaping our understanding of Earth's geological structure.
Mantle (MNT) has surged 15% to $1.36 driven by whale accumulation, a new staking partnership with Bybit, increased open interest, and exchange outflows, indicating strong short-term bullish momentum. However, heightened leverage and profit-taking by large investors could lead to increased volatility, making the sustainability of this rally uncertain.
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.
Scientists have discovered a rhythmic pulsing in the Earth's mantle beneath the Afar region in Ethiopia, linked to the ongoing rifting of tectonic plates, which may lead to the formation of a new ocean basin, revealing new insights into Earth's geological processes.
A new study suggests that Earth's core is leaking small amounts of gold and other heavy metals into the mantle, which then reach the surface through volcanic activity like Hawaii's islands, providing evidence of core-mantle interaction and potential sources of Earth's gold supply.
A new study provides evidence of a massive deep mantle superplume beneath Africa, driving volcanic activity and causing the continent to split along the East African Rift System, with gases from deep within Earth's mantle supporting this theory.
A recent study published in Nature Geoscience reveals that Earth's core may be leaking iron into the mantle, challenging the long-held belief of a stable interior. Through high-pressure experiments and geodynamic modeling, researchers found that temperature gradients could cause iron isotopes to migrate from the core to the mantle. This discovery suggests a more dynamic Earth, with implications for understanding geological processes, plate tectonics, and the planet's magnetic field. The findings highlight Earth's interior as a constantly shifting and evolving system.
The Indian Ocean gravity hole, the deepest dent in Earth's gravitational field, is located in the Laccadive Sea, southwest of India. This geoid low, discovered in 1948, was recently explained by a study using computer models to simulate Earth's mantle and tectonic plate movements over 140 million years. The study suggests the gravity hole formed after the ancient Tethys Ocean's crust sank beneath the Eurasian plate, displacing dense material and weakening gravity in the region. Further confirmation is needed through earthquake data.
Scientists have discovered a massive ocean beneath the Earth's crust, stored in a mineral called ringwoodite, which contains three times more water than all the surface oceans combined. This finding, based on seismic data, suggests a whole-Earth water cycle and explains the abundance of surface water. The discovery highlights the unique properties of ringwoodite, which can trap water in a sponge-like state, and adds to recent significant scientific discoveries.

New research indicates that Earth's inner core has been spinning unusually slowly for the past 14 years, potentially lengthening Earth's days by thousandths of a second. This phenomenon, known as "backtracking," has been confirmed through seismic data analysis, though the changes are imperceptible to humans. Further research is needed to understand the long-term trends and causes of this slowdown.
