Effect of different ions on dissolution rates of silica and feldspars at high pH
Karen Scrivener, Barbara Lothenbach, Mahsa Bagheri, Mahdieh Shakoorioskooie
The dissolution kinetics of silica-containing minerals in aggregates influences strongly the process of ASR in concrete. In this paper, the effect of different ions on the dissolution rates of SiO2 (amorphous and quartz) and feldspars at high pH values was ...
PERGAMON-ELSEVIER SCIENCE LTD2022Rock strength properties of granitic rocks in Yosemite Valley, Yosemite National Park, California
Federica Sandrone, Michel Jaboyedoff
Yosemite National Park, located in the central part of California’s Sierra Nevada mountains, is a glacially carved landscape filled with iconic rock formations such as Cathedral Peak, El Capitan, and Half Dome. Igneous rocks, consisting primarily of variat ...
U.S. Geological Survey2020Plagioclase Glomerocrysts: taking the pulse of volcanic eruptions
Anders Meibom, Stéphane Laurent Escrig, Anders McCarthy
Volcanic eruptions result from complex interplay of magmatic processes including the ascent and storage of magma in the crust, volatile exsolution and crystallization. The dynamics of crystallization in shallow subvolcanic systems and the consequences of i ...
2019Weekly to monthly time scale of melt inclusion entrapment prior to eruption recorded by phosphorus distribution in olivine from mid-ocean ridges
Anders Meibom, Stéphane Laurent Escrig, Othmar Müntener, Lukas Baumgartner, Mélina Manzini
Melt inclusions (MIs) hosted in euhedral olivine have been proposed to represent droplets of primary melt, protected from processes occurring near Earth's surface during eruption. The complex zoning of phosphorus (P) in some olivines and the presence of a ...
Geological Soc Amer, Inc2017Short magmatic residence times of quartz phenocrysts in Patagonian rhyolites associated with Gondwana breakup
Anders Meibom, Stéphane Laurent Escrig, Lukas Baumgartner, Susanne Seitz
A key parameter in the study of magma evolution is the time scale on which magmatic processes occur. Using nanoscale secondary ion mass spectrometry (NanoSIMS), SIMS, and cathodoluminescence (CL) analyses, we have measured titanium (Ti) diffusion profiles ...
Geological Society of America2016A Microstructure-Based Model to Characterize Micromechanical Parameters Controlling Compressive and Tensile Failure in Crystallized Rock
A discrete element model is proposed to examine rock strength and failure. The model is implemented by UDEC which is developed for this purpose. The material is represented as a collection of irregular-sized deformable particles interacting at their cohesi ...
Springer Verlag2014Coupled semi‐analytical approach of CO2 injection induced caprock deflection
This study focuses on a specific problem related to the caprock deformation induced by the in-jection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and ...
