A new study from the University of British Columbia reveals that magmatism of Earth’s current crust’s precursor formed three rocks—tonalite, trondhjemite and granodiorite, known collectively ...
Carol Frost joined the University of Wyoming faculty in 1983 as an assistant professor in the Department of Geology and Geophysics, where she established the radiogenic isotope geology laboratory. Her ...
I have on-going projects to study: Processes in intrusions: How big are magma chambers? How do igneous cumulates form? What processes occur in magma chambers? For example, is compaction or porous ...
The gold-bearing quartz-carbonate veins are all hosted within sheared and altered gabbro dykes, at the contact with the tonalite. The dykes are commonly 15 to 20 metres wide and may be interpreted as ...
Wabamisk covers volcano-sedimentary units of the Eastmain greenstone belt, surrounded by intrusive rocks (tonalite, granodiorite). Several extensive east-west shear zones mark the main lithological ...
