Summary

Story summary

Large-low-shear-velocity provinces (LLVPs) at the Earth's core-mantle boundary slow seismic waves and may influence volcanic hotspots like Hawaii, releasing essential chemicals for life.
Dr. Yoshinori Miyazaki and colleagues propose LLVPs are remnants of Earth's early history and that core leakage could explain the well-mixed mantle observed today.
Their findings are published in Nature Geoscience.
Understanding these provinces could illuminate Earth's evolution and the conditions that support life.
