Abstract

Thermal modeling independently predicts the observed relationships among basalt chemistry, ridge depth, and crustal thickness resulting from temperature variations in the mantle. Beneath the shallowest and deepest ridge axes, temperature differences of approximately 250oC in the subsolidus mantle are required to account for the global systematics. -from Authors

University Distinguished Service Professor

Dr. Klein's research focuses on the geochemistry of oceanic basalts, using diverse tools of major, trace and isotopic analyses. Her research involves sea-going expeditions to sample and map the ocean floor.
