Mysterious Anomaly Discovered in Earth's Mantle - Could it be a Remnant from the Past?
Researchers have recently discovered an unprecedented anomaly deep within the Earth’s mantle that has never before been observed. Dubbed the ‘Galle Anomaly’, the region is located around 2,900 kilometers below the Earth’s surface and is likely the remnant of an ancient tectonic plate. Scientists suspect that the anomaly is composed of several different types of rock, including some that are not usually found in the mantle, indicating that the material originated elsewhere. This finding could provide new insight into the history of the Earth’s formation and evolution.
