- Title
Determination of the Density of the Earth's Core Based on the Equations of State of Iron and Titanium at High Pressures and Temperatures.

Medvedev, A. B.
- Abstract
Using previously developed equations of state for iron and titanium, the density of the Earth's core was calculated at a mass content of titanium in a mixture with iron of ~20%. This concentration is taken from data for high-titanium (HT) basalts, the formation of which in large igneous provinces is hypothetically associated with the ascent of thermal plumes in the mantle from the core to the surface. The calculated density on pressure dependences in the outer liquid and inner solid cores satisfactorily agree with the data of the preliminary reference Earth model (PREM).
