Local bulk composition effects on metamorphic mineral assemblages

P Lanari, M Engi - Reviews in Mineralogy and …, 2017 - pubs.geoscienceworld.org
Plate tectonic forcing leads to changes in the physical conditions that affect the lithosphere.
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 …

The effect of Mn on mineral stability in metapelites revisited: new ax relations for manganese‐bearing minerals

RW White, R Powell, TE Johnson - Journal of Metamorphic …, 2014 - Wiley Online Library
The a–x relations recently presented in White et al.(, Journal of Metamorphic Geology, 32,

Progress relating to calculation of partial melting equilibria for metapelites

RW White, R Powell, TJB Holland - Journal of metamorphic …, 2007 - Wiley Online Library
Improved activity–composition relationships for biotite, garnet and silicate liquid are used to
construct updated P–T grids and pseudosections for high‐grade metapelites. The biotite …

[图书][B] Atlas of migmatites

EW Sawyer - 2008 - books.google.com
Migmatites are highly heterogeneous rocks found in high-grade metamorphic environments;

On thermobarometry

R Powell, TJB Holland - Journal of Metamorphic Geology, 2008 - Wiley Online Library
Thermobarometry, the estimation of the pressure–temperature (P–T) conditions of
metamorphism, can be undertaken by using pseudosection calculations as well as by …

A thermodynamic model for titanium and ferric iron solution in biotite

L Tajčmanová, JAD Connolly… - Journal of metamorphic …, 2009 - Wiley Online Library
Recent crystallographic data indicate that in biotite Ti orders preferentially onto the M2
octahedral site rather than onto the M1 site as assumed in previous solution models for K2O …

Paleoproterozoic tectonic evolution of the Trans-North China Orogen: toward a comprehensive model

P Trap, M Faure, W Lin, N Le Breton, P Monié - Precambrian Research, 2012 - Elsevier
In this contribution we present a reconstruction of the overall lithotectonic architecture, from
inner zones to external ones, of the Paleoproterozoic Trans-North China Orogen, within the …

Major-element geochemistry of pelites

JB Forshaw, DRM Pattison - Geology, 2023 - pubs.geoscienceworld.org
Pelites (shales and mudstones) are arguably the most important rock type for interpreting
metamorphism. Their significance derives from their widespread occurrence and the range …
