Magmin_pt: an Excel-Based Mineral Classification and Geothermobarometry Program for Magmatic Rocks

, 2022
Igneous rock forming minerals carry valuable information from the deep earth that is not directly accessible to the surface. Each phase represents physico-chemical conditions under which various magmatic processes occur at a wide range of depths from ...

Mineral chemistry and geothermobarometry of metabasites of the Majerad igneous-metamorphic complex (SE of Shahrood)

Journal of Economic Geology, 2020
Introduction Thermobarometric models based on the chemical equilibrium among coexisting mineral-mineral or mineral-melts pairs are useful tools widely used to estimate the P-T path and chemical evolution during igneous processes. The high sensitivity of

Natural evidence for garnet-spinel transition (GST) in the Earth's mantle

, 2008
This study based on compiled world-wide garnet peridotite data confirms the GST in high P and T conditions, which was obtained from Al-free experimental system (MgO-Cr~2~O~3~-SiO~2~) by Klemme (2004). A new spinel-phase peridotite zone, garnet peridotite

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 287-310, May 2026.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...

Geothermobarometry, structure, and geochronology of low-grade rocks in the southern Acatlán Complex, San Martín Zacatepec, Oaxaca

Revista Mexicana de Ciencias Geológicas
The Acatlán Complex (AC) in southern Mexico is a critical lithodemic province for Paleozoic paleoreconstructions. It is mainly composed of low-grade volcano-sedimentary sequences, yet quantitative geothermobarometric data are scarce in the literature ...
