Chemical fingerprints from volcanic rock offer hints of what’s happening in the mantle below the area where three rift zones ...

A plume of molten rock rising from the depths of the Earth in heartbeat-like pulses is slowly tearing Africa apart—and will one day create a new ocean. This is the conclusion of an international team ...

A spot in eastern Africa called the Afar Triangle marks the meeting point of three rift zones—lines where Earth’s crust is being rent apart. Researchers haven’t been sure exactly what drives this ...

They formed when extraordinarily hot plumes of magma rose from the mantle to Earth's surface (once magma reaches Earth's surface, it's called lava) during the Archaean period (2.5 billion to 4 ...

Magma: hot stuff, coming through. A better understanding of the movement of magma at plate boundaries could help predict volcanic eruptions more accurately, ... beneath another plate. Tectonic plates ...

Towards A Better Understanding Of Hot Spot Volcanism Date: February 4, 2008 Source: Institut de Recherche Pour le Développement Summary: Researchers investigated the phenomena that led to the ...

When Earth was young and hot, during the Hadean eon (4.6 billion to 4 billion years ago), the planet was first covered with a magma ocean and then, as the planet cooled, a solid rock surface.

Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate Date: June 20, 2023 Source: Georgia Institute of Technology Summary: A team of scientists has observed past episodic ...

Hot block. Simulations of Yellowstone’s underbelly suggest that the relatively cold remnants of an ancient tectonic plate (blue) block the heat from a rising mantle plume (red) from reaching the ...

The mantle, though not as hot as the earth’s core, is hot enough that some rocks start to melt. This molten rock, called magma, is less dense than the surrounding rocks in the mantle. Due to this ...

Enough hot rock sits beneath Yellowstone National Park to fill the Grand Canyon nearly 14 times over, according to our best view yet of the supervolcano that lies below the famous landscape.
