How 'Ghost' Plume Under Oman Altered India's Path 40 Million Years Ago
Scientists have discovered a hidden plume beneath Oman that influenced the movement of India millions of years ago. This plume, known as the Dani plume, shifted the trajectory of the Indian tectonic plate after its collision with Eurasia. Despite being inactive in terms of volcanic activity, the plume's pressure played a crucial role in shaping the region's topography. The findings were published in the journal Earth and Planetary Science Letters.
Scientists have revealed that an underground phenomenon in Oman changed the direction of India millions of years ago. A magma plume under the Salma Plateau in Oman affected the trajectory of the Indian tectonic plate after it collided with Eurasia. The plume, named the Dani plume, is considered a 'ghost' plume as it does not trigger volcanic eruptions. The Salma Plateau, up to 6,600 feet high, likely formed because of this plume.
The research, published in Earth and Planetary Science Letters, shows that the Dani plume is active and dates back around 40 million years. The collision between the Indian and Eurasian plates near Oman led to a change in the Indian plate's direction. The shear stress produced by the plume was identified as the reason for this change.
