Titanite geochemistry and textures: Implications for magmatic and post-magmatic processes in the Notch Peak and Little Cottonwood granitic intrusions, Utah
Autor: Porter K. Henze, Eric H. Christiansen, Bart J. Kowallis, Michael J. Dorais, Haley D. Mosher, Lauren M. Franzen, Alec J. Martin, Peter I. Nabelek
Publikováno v: American Mineralogist. 108:226-248
Textural and compositional variations in titanite constrain the roles of magma mixing and hydrothermal alteration in two plutons in central Utah: the Jurassic Notch Peak and the Oligocene Little Cottonwood stocks. In the Notch Peak intrusion, magmati

Formation of metasomatic tourmalinites in reduced schists during the Black Hills Orogeny, South Dakota
Autor: Peter I. Nabelek
Publikováno v: American Mineralogist. 106:282-289
Tourmaline is a common mineral in granites and metamorphic rocks in collisional orogens. This paper describes graphite-bearing, metasomatic tourmalinites in sillimanite-zone schists of the Proterozoic Black Hills Orogen, South Dakota. The tourmalinit

Clumped isotope thermometry of calcite and dolomite in a contact metamorphic environment
Autor: John M. Eiler, Peter I. Nabelek, Max K. Lloyd
Publikováno v: Geochimica et Cosmochimica Acta. 197:323-344
Clumped isotope compositions of slowly-cooled calcite and dolomite marbles record apparent equilibrium temperatures of roughly 150-200 °C and 300-350 °C, respectively. Because clumped isotope compositions are sensitive to the details of T-t path wi

Properties of fluids attending variable recrystallization of quartzite during contact metamorphism in the White‐Inyo Range, California
Autor: Sven Morgan, Peter I. Nabelek, S. K. Stephenson, James John Student
Publikováno v: Journal of Metamorphic Geology. 35:357-369
Fluid inclusions in the metamorphic aureole of the Eureka Valley-Joshua Flat-Beer Creek (EJB) pluton in the White-Inyo Range, California, reveal the compositions and origin of fluids that were present during variable recrystallization of quartzite wi

Fluid inclusion examination of the transition from magmatic to hydrothermal conditions in pegmatites from San Diego County, California
Autor: Peter I. Nabelek, Elizabeth M. Gammel
Publikováno v: American Mineralogist. 101:1906-1915
Thermometric properties and compositions of fluid inclusions in quartz are used to constrain the roles that fluid-soluble elements, principally Li, B, Cl, and F, have in controlling the transition from magmatic to hydrothermal mineral paragenesis in

Fluid-controlled grain boundary migration and switch in slip systems in a high strain, high temperature contact aureole, California, USA
Autor: Peter I. Nabelek, James John Student, Joseph F. Sadorski, Sven Morgan
Publikováno v: Tectonophysics. 676:42-55
Within the highly strained aureole surrounding the Eureka Valley–Joshua Flat–Beer Creek (EJB) composite pluton of eastern California, an inversion in microstructures and crystallographic preferred orientations (CPOs) exists with distance from the
