Historically, the field of metamorphic petrology has advanced largely due to the implementation of techniques for quantifying the chemical compositions of rocks in situ. Today, concentrations of major and trace elements are routinely measured on the micrometer scale with instruments like the Electron Probe Microanalyzer (EPMA) and others. Quantitative chemical maps of minerals produced by […]
A34: Deformation of Dry High-pressure Eclogites DuringTectonic Slicing of Subducted Oceanic Lithosphere: A Case Study from the Monviso Ophiolite, Italy
The Alps contain records of deeply subducted oceanic lithosphere that detached at high-pressure (HP) conditions and later exhumed to the surface. These HP ophiolite bodies are key to understanding important geodynamics processes occurring along the plate-interface within subduction zones, yet the nature of their detachment and recovery is not well-understood. For example, HP ophiolites from […]
