New research maps how Earth's rigid outer layer—the lithosphere—controls mountain ecosystems, rare earth element distribution, and planetary evolution. Scientists are uncovering sharp boundaries between the lithosphere and mantle below, while also revealing hidden geological structures affecting regions like California's Central Valley.
·Mountain vegetation resilience is modulated from below by lithospheric properties, not just surface climate
·Rare earth ore deposits form in mantle lithosphere altered by subduction, linking geology to critical mineral supplies
·A sharp velocity discontinuity exists at the lithosphere-asthenosphere boundary, detectable through seismic noise analysis
·A previously unmapped geologic fault runs beneath Visalia, California, revealing hidden crustal architecture
·Global atlas pinpoints where rare earth elements originate in Earth's deep interior
