The two most commonly invoked processes for generating plagiogranites in mid-ocean ridge environments are extended fractional crystallization of mid-ocean ridge basalt (MORB) magma and “hydration melting” of hot, dry MOR gabbro initiated by the i

Partially crystalline hornblende gabbro inclusions from the Little Glass Mountain Rhyolite contain euhedral plagioclase, orthopyroxene, hornblende, and apatite crystals in contact with interstitial rhyolitic (71–76% SiO2) glass. Textural and minera

The Cambrian Mount Simon Sandstone is the major target reservoir for ongoing geologic carbon dioxide (CO2) sequestration demonstrations throughout the midwest United States. The potential CO2 reservoir capacity, reactivity, and ultimate fate of injec

Small volumes of alkalic mafic intrusions are spatially associated with Cretaceous to Early Tertiary granodioritic to granitic intrusions in the batholithic province of southwestern Montana. The mafic rocks generally occur near the contacts of the Bo

Analytical expressions for the variation in D La and D Yb with increasing liquid SiO2 for olivine, plagioclase, augite, hornblende, orthopyroxene, magnetite and ilmenite (Brophy in Contrib Mineral Petrol 2008, online first) have been combined with nu

Magma ascent, decompression-induced H2O exsolution and crystallization is now recognized as an important process in hydrous subduction zone magmas. During the course of such a process calculations suggest that the ascent rate of a degassing and cryst

The origin of felsic magmas (>63% SiO2) in intra-oceanic arc settings is still a matter of debate. Two very different processes are currently invoked to explain their origin. These include fractional crystallization of basaltic magma and partial melt

The solubility of copper in a sulfur-saturated basaltic melt has been determined at 1245°C as a function of fO2 and fS2. Copper solubilities at log fO2 values between −8 and −11 fall into two distinct populations as a function of fS2. At log fS2
