Variation of Fe, Al, and F Substitution in Titanite (Sphene)

Autor: Bart J. Kowallis, Eric H. Christiansen, Michael J. Dorais, Anthony Winkel, Porter Henze, Lauren Franzen, Haley Mosher

Publikováno v: Geosciences, Vol 12, Iss 6, p 229 (2022)

Titanite is an important mineral in petrochronology studies. Understanding chemical signatures of titanite from different environments can provide significant data in unraveling the complex histories recorded in their textures and compositions. Using

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

Nature and Origin of Zoned Polymetallic (Pb-Zn-Cu-Ag-Au) Veins from the Bingham Canyon Porphyry Cu-Au-Mo Deposit, Utah

Autor: Jens Gibbs, David H. Tomlinson, Mackenzie Sorensen, Michael J. Dorais, Diego P. Fernandez, Rudy Ganske, Nicholas Vetz, Eric H. Christiansen, Jeffrey D. Keith

Publikováno v: Economic Geology. 116:747-771

Polymetallic veins (Pb-Zn-Cu-Ag-Au) at the world-class Bingham Canyon, Utah, porphyry Cu-Au-Mo deposit have long been recognized, but poorly understood. They are laterally zoned outward from the center of the porphyry deposit transitioning from Fe-Cu

Fallout tuffs in the Eocene Duchesne River Formation, northeastern Utah—ages, compositions, and likely source

Autor: Douglas A. Sprinkel, Michael A. Jensen, Michael J. Dorais, Brian R. Jicha, Bart J. Kowallis, Casey Webb, Eric H. Christiansen

Publikováno v: Geology of the Intermountain West. 7:1-27

Thin fallout tuffs are common in the terrestrial deposits of the Eocene Duchesne River Formation on the flanks of the Uinta Mountains of eastern Utah. Their ages and compositions provide new insight into the tectonic events and magmatic history of th

Vapor Transport and Deposition of Cu-Sn-Co-Ag Alloys in Vesicles in Mafic Volcanic Rocks

Autor: Jacob Hunter, Jeffrey D. Keith, Elizabeth A.O. Hunter, Michael J. Dorais, Eric H. Christiansen, Nichelle L. Hann, Zoltán Zajacz

Publikováno v: Economic Geology. 115:279-301

Metallic sublimates coated by sulfides and chlorides line the vesicle walls of mafic volcanic lava and bombs from Kīlauea, Vesuvius, Etna, and Stromboli. The metallic sublimates were morphologically and compositionally similar among the volcanoes. T
