Transient Porosity During Fluid‐Mineral Interaction, Part 2: Reconstruction Using Generative AI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Quantifying fluid–rock interactions within the lithosphere is vital for both geological processes and applications such as CO2 ${\text{CO}}_{2}$ storage and geothermal energy development. Mineral replacement reactions generate transient pore networks that enhance fluid flow, yet many pores become isolated once reactions are completed, reducing

Geochemistry of the Guaxupe Granulites, Minas Gerais, Brazil

, 1998
Geochemical data for granulite terrain are presented from the northernmost portion of the Guaxupe Massif, at Mantiqueira Province, SE Brazil. Several types of granulites are recognized in the area: basic, intermediate and acid granulite.

Along‐Strike Seismic Structure of the Andreanof Aleutian Arc Segment and Implications for the Formation of Continental Crust

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Crust formed in volcanic arcs is accreted to continents over geologic time, serving as the source material for new continental crust in Earth's present and recent past. Geochemically, arcs are found to be significantly more mafic than bulk continental crust.

Petrology of granulites from Anakapalle-evidence for Proterozoic decompression in the Eastern Ghats, India

, 1994
The granulite complex at Anakapalle, which was metamorphosed at ~1000 Ma, comprises orthopyroxene granulites, leptynite, khondalite, mafic granulites, calc-silicate rock, spinel granulites, and two types of sapphirine granulites-one quartz-bearing and ...

Influence of loading and heating processes on elastic and geomechanical properties of eclogites and granulites

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Increased knowledge of the elastic and geomechnical properties of rocks is important for numerous engineering and geoscience applications (e.g. petroleum geoscience, underground waste repositories, geothermal energy, earthquake studies, and hydrocarbon ...

Constraints on the rheology of the lower crust in a strike-slip plate boundary: evidence from the San Quintín xenoliths, Baja California, Mexico [PDF]

Solid Earth, 2017
The rheology of lower crust and its transient behavior in active strike-slip plate boundaries remain poorly understood. To address this issue, we analyzed a suite of granulite and lherzolite xenoliths from the upper Pleistocene–Holocene San Quintín ...

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Granulites, CO2 and graphite

, 2012
Externally derived, pure CO2 that mixes with a carbon-(under)saturated C-O-H -fluid in lower crustal granulites may result in graphite precipitation if the host-rock oxygen fugacity (f(O2)^rock) is below the upper f(O2) limit of graphite.

Mid-crustal shear zone development under retrograde conditions: pressure–temperature–fluid constraints from the Kuckaus Mylonite Zone, Namibia [PDF]

Solid Earth, 2016
The Kuckaus Mylonite Zone (KMZ) forms part of the larger Marshall Rocks–Pofadder shear zone system, a 550 km-long, crustal-scale strike-slip shear zone system that is localized in high-grade granitoid gneisses and migmatites of the Namaqua Metamorphic ...

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...
