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...

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 ...

Satellite Data Reveals How Earth's Crust Is 'Dripping' Beneath Turkey
The sinking is due to the multi-stage lithospheric dripping — a phenomenon named for the instability of rocky material that creates the crust and upper mantle of the Earth

Study Reveals Ultra-Low Velocity Zones May Be More Common in Earth's Mantle Than Previously Thought
A new study published in AGU Advances has unveiled intriguing findings about ultra-low velocity zones (ULVZs) in Earth's mantle, suggesting these mysterious features might be more widespread than previously thought.ULVZs, which are known to dramatically slow seismic waves by up to 50%, have long been associated with volcanic hotspots such as Hawaii...

Gargantuan Waves in Earth’s Mantle May Cause Continental Uplift, New Study Reveals
New research has unveiled that enormous waves within Earth's mantle are instrumental in forming high plateaus and dramatic cliff formations. This study explores how the rifting of continents triggers these mantle waves, which then propagate inward and lead to the rise of plateaus. By analyzing escarpments formed during the breakup of Gondwana, scie...

China's Ultra-Deepwater Drilling Ship Mengxiang Sets Sail To Reach Earth's Mantle
China has unveiled its first ocean drilling vessel, the Mengxiang, which is designed to delve into the Earth's crust and explore the mysteries of the mantle. If successful, this will mark humanity's first exploration into the upper mantle.

Earth's Mantle 60 Degrees Hotter Than Thought: Study
The mantle - the mostly solid, rocky part of Earth's interior - is about 60 degrees Celsius hotter than previously thought, a new study has found.

Water Exists Deeper In Earth Than Thought: Study
Water exists far deeper in the Earth - about 400 to 600 kilometres into the mantle - than previously believed, researchers including one of Indian origin have found.

Earth has a secret reservoir of water, say scientists
Writing in the journal Nature, scientists on Wednesday said they had found an elusive mineral pointing to the existence of a vast reservoir deep in Earth's mantle, 400-600 kilometres (250-375 miles) beneath our feet.
