Persistent Activity and Crater Formation at Telica Volcano Driven by the Shallow Hydrothermal System

Autor: Peter LaFemina, Emilie Saucier, Maureen Feineman, Armando Saballos

Telica volcano is a persistently restless volcano with activity expressed as long-lived high-temperature fumaroles and magmatic degassing, high rates of background seismicity and frequent (sub-decadal) explosive, phreatic to phreatomagmatic eruptive

Many of Earth's volcanoes experience well‐defined states of “quiescence” and “unrest,” with unrest occasionally culminating in eruption. Some volcanoes, however, experience an unusually protracted (i.e., decades‐long) period of noneruptiv

Trace element and isotopic zoning of garnetite veins in amphibolitized eclogite, Franciscan Complex, California, USA

Autor: Regina Mertz-Kraus, Emilie H. Lozier, Maureen Feineman, Thomas Zack, Alicia M. Cruz-Uribe, F. Zeb Page, Kouki Kitajima, Dorrit E. Jacob

Here we present major element, trace element, and oxygen isotope data for garnet from an amphibolitized eclogite block from Ring Mountain, Franciscan Complex, California, USA. Garnetite veins 1–5 cm thick are laterally continuous up to 10 m within

Decoupling of zircon U–Pb and trace-element systematics driven by U diffusion in eclogite-facies zircon (Monviso meta-ophiolite, W. Alps)

Autor: Maureen Feineman, Joshua M. Garber, Simon Matthews, Andrew J. Smye, Andrew R.C. Kylander-Clark

Publikováno v: Contributions to Mineralogy and Petrology. 175

Zircon is widely used to date metamorphic processes, particularly due to slow cation diffusion under crustal conditions. Here, we present laser-ablation depth profiling data that demonstrate rapid U diffusion in partially altered, high-pressure zirco

Let there be water: How hydration/dehydration reactions accompany key Earth and life processes#

Autor: Alessandra Ciappa, Donato Giovannelli, Jörg Hermann, Fabrizio Nestola, Maureen Feineman, Christopher J. Butch, Angelina Cordone, Agnès Elmaleh, H. J. Cleaves, Alberto Vitale Brovarone, Manuele Faccenda

Water plays a key role in shaping our planet and making life possible. Given the abundance of water on Earth's surface and in its interior, chemical reactions involving water, namely hydration and dehydration reactions, feature prominently in nature
