A diagram showing how Earth's crust and upper mantle (together known as the lithosphere) could be dripping into the mantle due to the Farallon slab. (Image credit: Hua et al. Nature Geoscience (2025)) ...
A diagram of the Earth's layers, including the transition zone ... (255 and 410 mi) deep, separates the upper and lower mantle. To get a closer look at what's going on down there, ...
An illustrative diagram showing the ancient subducted 'slab' the team resolved at present day. It has a direct impact on the large-scale lowermost mantle structures known as 'superplumes'.
The Afar junction is the point at which the Arabian, Nubian, and Somalian plates meet, each departing in their own directions to leave a widening gap under the Afar Triangle. Eventually, the crust ...
Because of Mantle’s requests to keep it in its existing condition, the home is a time capsule. Located at 319 South Quincy Street, the Mantle family purchased the property in 1934, and it ...
The mantle wave penetrates far beneath the continent, and the uplift and kimberlite volcanism migrate inland as well. A broad plateau has formed on the surface, and it is punctured with kimberlite ...
A diagram showing a slab of Earth's crust that sank into the mantle roughly 250 million years ago. SPS stands for Southeastern Panthalassa Subduction, the name given to the newly discovered ...
A diagram illustrating two types of lithospheric drip. (Image credit: Julia Andersen / University of Toronto) One possible sign is that lithospheric dripping can pull the crust above into wrinkly ...
Since the early 1960s, humans have attempted to drill down to the Earth's mantle. Russia holds the record for the deepest man-made hole in the world at more than 40,000 feet deep. That's 7.6 miles.
Maier et al. have sampled a class of volcanic rocks called komatiites, which are indirect samples of the deepest portions of the Earth's mantle mainly from the Archaean era. It is generally ...
Some regions of the lowermost mantle have been observed to have seismic wave speed reductions of at least 10 per cent2,3,4,5,6,7, ... A diagram of the best-fitting ULVZ structure is shown in Fig. 4.
