Global correlations of ocean ridge basalt chemistry with axial depth and crustal thickness.
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.

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.
