文摘
- •
We present >650 strain measurements within the Sierra Nevada arc in California to quantify crustal deformation.
- •
Most tectonic shortening and magma emplacement must be accommodated by downward displacements of crustal materials.
- •
Both tectonism and magmatism control the crustal thickness and elevation with modification by surface erosion.
