Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).

Abstract We have developed the Quantitative Microanalysis Explorer, or QME‐Tool, a web‐based platform for visualization of large imaging data sets and interrogation of quantitative elemental maps acquired by electron microprobes. Using a combination of open‐source JavaScript libraries and custom scripts, the QME‐Tool can be used to quickly identify ...

Abstract The evolution of the Isthmus of Panama during the Miocene resulted in climatic shifts leading to global cooling, reorganization of ocean currents, and regional mass extinctions. The causes of this change in ocean circulation between ∼15 and 5 Ma have been debated, with various tectonic scenarios being proposed as explanations for this event ...

Emergent Feedbacks Between Progressive Serpentinization, Interface Weakening, and Subduction Rates
Abstract During subduction, the downgoing oceanic crust is exposed to high temperatures in the mantle wedge, causing volatile‐bearing minerals to break down and release hydrous fluids into the forearc. These fluids percolate upwards, reacting with the mantle wedge to form hydrated ultramafic lithologies, including serpentinite.
