The mid-Cretaceous Peninsular Ranges orogeny: a new slant on Cordilleran tectonics? III: the orogenic foredeep
Autor: Robert S. Hildebrand, Janok P. Bhattacharya, Joseph B. Whalen
Publikováno v: Canadian Journal of Earth Sciences. 60:214-262
The Cretaceous Western Interior Basin reflects the interplay between the North American craton and allochthonous terranes to the west. We divide the basinal stratigraphy into three successions, Aptian–Albian, Cenomanian–Turonian, and Santonian–

Crustal eduction and slab-failure magmatism in an Orosirian (2.05–1.80 Ga) postcollisional cratonic foredeep: geochronology of Seton volcanics and Compton laccoliths, Tu Cho (Great Slave Lake), NWT, Canada

Three Orosirian basins and associated foreland thrust-fold belts are preserved on the margins of the Slave craton. All three are related to orogenic belts where oceans opened and later closed, uniting new crustal partners. The Great Slave basin diffe

The mid-Cretaceous Peninsular Ranges orogeny: a new slant on Cordilleran tectonics? I: Mexico to Nevada
Autor: Joseph B. Whalen, Robert S. Hildebrand
Publikováno v: Canadian Journal of Earth Sciences. 58:670-696
The Peninsular Ranges orogeny occurred during the mid-Cretaceous at ∼100 Ma and affected rocks from southern Mexico to Alaska. The event resulted from the closing of an Early Cretaceous marine arc trough, named the Bisbee–Arperos seaway in Mexico

The mid-Cretaceous Peninsular Ranges orogeny: a new slant on Cordilleran tectonics? II: northern United States and Canada
Autor: Robert S. Hildebrand, Joseph B. Whalen
Publikováno v: Canadian Journal of Earth Sciences. 58:697-719
The mid-Cretaceous Peninsular Ranges orogeny occurred in the North American Cordillera and affected rocks from Mexico to Alaska. It formed when a marine trough, open for ∼35 million years, closed by westerly subduction beneath a 140–100 Ma arc co

Using magmatic biotite chemistry to differentiate barren and mineralized Silurian–Devonian granitoids of New Brunswick, Canada
Autor: David R. Lentz, Joseph B. Whalen, Christopher R.M. McFarlane, Z Azadbakht
Publikováno v: Contributions to Mineralogy and Petrology. 175
The geochemistry of biotite crystals from thirty fertile and barren Silurian–Devonian granitoids of New Brunswick, Canada, was studied in situ using electron microprobe and laser ablation inductively coupled plasma-mass spectrometry to investigate

International audience; The use of molybdenum as a quantitative paleo-atmosphere redox sensor is predicated on the assumption that Mo is hosted in sulfides in the upper continental crust (UCC). This assumption is tested here by determining the minera

Resolving the crustal composition paradox by 3.8 billion years of slab failure magmatism and collisional recycling of continental crust
Autor: Robert S. Hildebrand, Joseph B. Whalen, Samuel A. Bowring
Publikováno v: Tectonophysics. :69-88
In the standard paradigm, continental crust is formed mainly by arc magmatism, but because the compositions of magma rising from the mantle are basaltic and continental crust is estimated to contain about 60% SiO2 and much less MgO than basalt, the t
