Figure 1: Extent of the LLSVPs in the lowermost mantle. Figure 2: Observed and predicted Stoneley mode splitting function maps. To explicitly test whether the density in the LLSVPs is higher or ...

The researchers recreated in the lab the materials, crushing pressures and infernal temperatures they believe exist in the lowermost mantle, nearly 2,900 kilometers (1,800 miles) below Earth's ...

Largely ignored in past research, the remote region between the lowermost mantle and the upper core is proving to be crucial in understanding the chemical and thermal evolution of the planet.

According to the accelerator mass spectrometry (AMS) dates, the lowermost level of the site is dated back to the sixth century BCE. This has been pointed out in the report - Excavations at ...
