Local bulk composition effects on metamorphic mineral assemblages

P Lanari, M Engi - Reviews in Mineralogy and …, 2017 - pubs.geoscienceworld.org

In response to such changes, notably the local temperature (T) and pressure (P), rocks …

Garnet: A rock-forming mineral petrochronometer

EF Baxter, MJ Caddick… - Reviews in Mineralogy …, 2017 - pubs.geoscienceworld.org
Garnet could be the ultimate petrochronometer. Not only can you date it directly (with an
accuracy and precision that may surprise some), but it is also a common rock-forming and …

Preservation of garnet growth zoning and the duration of prograde metamorphism

MJ Caddick, J Konopásek, AB Thompson - Journal of Petrology, 2010 - academic.oup.com
Chemically zoned garnet growth and coeval modification of this zoning through diffusion are
calculated during prograde metamorphic heating to temperatures of up to 850° C. This …

Theoretical modeling of monazite growth in a low-Ca metapelite

FS Spear, JM Pyle - Chemical Geology, 2010 - Elsevier
Monazite growth and composition has been modeled in the system K2O–Na2O–CaO–MnO–
MgO–FeO–Al2O3–SiO2–H2O–Y2O3–Ce2O3–P2O5–F and a pseudosection is presented …

Scales of disequilibrium and rates of equilibration during metamorphism

WD Carlson - American Mineralogist, 2002 - pubs.geoscienceworld.org
Mounting evidence suggests that partial disequilibrium—meaning disequilibrium for some
elements, but not for others—may be a common but rarely detected phenomenon during …

Diffusion-limited REE uptake by eclogite garnets and its consequences for Lu–Hf and Sm–Nd geochronology

S Skora, LP Baumgartner, NJ Mahlen… - … to Mineralogy and …, 2006 - Springer
Abstract Garnets from the Zermatt-Saas Fee eclogites contain narrow central peaks for Lu+
Yb+ Tm±Er and at least one additional small peak towards the rim. The REE Sm+ Eu+ Gd+ …

Retrograde processes in migmatites and granulites revisited

M Brown - Journal of Metamorphic Geology, 2002 - Wiley Online Library
Many migmatites and granulites preserve evidence of a clockwise P–T evolution involving
decompression (decrease in P) while close to the thermal peak. The extent of post‐thermal …

Discrimination of thermodynamic and kinetic contributions to the heavy rare earth element patterns in metamorphic garnet

M Konrad‐Schmolke, R Halama… - Journal of …, 2023 - Wiley Online Library

Trace element mapping by LA-ICP-MS: assessing geochemical mobility in garnet

T Raimondo, J Payne, B Wade, P Lanari… - … to Mineralogy and …, 2017 - Springer
A persistent problem in the study of garnet geochemistry is that the consideration of major
elements alone excludes a wealth of information preserved by trace elements, particularly …
