Scientists Uncover Mysterious ‘Ghost’ Plume Beneath Oman

A groundbreaking discovery has been made by scientists who believe they have identified a ‘ghost’ plume for the first time. This elusive column of hot rock, rising from Earth’s core beneath Oman, has puzzled researchers due to its lack of surface volcanic activity, unlike typical plumes.

Mantle plumes, such as this ghost plume, are crucial in the dynamics of heat, pressure, and movement within the Earth. They play a significant role in various geological processes, including plate tectonics, the evolution of life, and the Earth’s magnetic field.

According to an international team of researchers, led by a recent study published in Earth and Planetary Science Letters, the ‘ghost’ plume named the Dani plume was identified beneath eastern Oman through a combination of seismic data analysis, computer modeling, and field measurements.

The researchers observed that seismic waves passing through the region slowed down, indicating the presence of hotter, softer rock beneath the surface. Additional evidence, such as seismic discontinuities at key geological boundary layers, further supported the existence of the ghost plume.

Based on the data collected, the Dani plume is estimated to be around 200–300 kilometers in diameter and up to 100–300 °C (212–540 °F) hotter than the surrounding mantle. This focused patch of rock may have influenced the movement of the Indian tectonic plate millions of years ago and continues to impact the topography of Oman today.

While this ghost plume discovery is a significant breakthrough, researchers suggest that there may be more similar phenomena waiting to be uncovered worldwide. These findings could lead to revisions in geological evolution models and a better understanding of heat distribution from the Earth’s core.

The study also hints at the possibility of more heat leaking from the core than previously estimated, prompting the need for further research to assess the long-term implications of this increased heat flux.

The research paper, detailing the discovery of the ‘ghost’ plume beneath Oman, has been published in Earth and Planetary Science Letters.
