AMERICANALMANAC (Alan Benson) - Chinese scientists find six unknown structures buried 1,800 miles beneath Earth's surface
A team of Chinese researchers used artificial intelligence to scan millions of seismic recordings and identified six never-before-documented formations deep at the boundary between Earth's mantle and its liquid outer core. The structures sit roughly 1,800 miles below the planet's surface, in one of the most extreme and least understood environments on Earth. Temperatures at […] The post Chinese scientists find six unknown structures buried 1,800 miles beneath Earth's surface appeared first on American Almanac .
A team of Chinese researchers used artificial intelligence to scan millions of seismic recordings and identified six never-before-documented formations deep at the boundary between Earth's mantle and its liquid outer core. The structures sit roughly 1,800 miles below the planet's surface, in one of the most extreme and least understood environments on Earth. Temperatures at the mantle-core boundary swing by about 1,000°C, nearly 1,800°F, across a relatively thin transition zone where solid, slow-moving rock meets liquid metal. The researchers described the formations as "deep-seated scatterers" and "thermochemical piles," terms that refer to regions where the rock composition or temperature differs sharply from the surrounding mantle…Open
