Tracking the Evolution of Mid Cenozoic Silicic Magma Systems in the Southern Chocolate Mountains Region, California Using Zircon Geochemistry and Quartz and Zircon Geothermometry
Chocolate Mountains zircon quartz geothermometer geochemistry
2015/1/16
During the mid Cenozoic, the Chocolate Mountains region of southeastern California experienced crustal extension slightly before, during, and after the main pulse of magmatism. This combined with mid-...
Thermal conditions during deformation of partially molten crust from TitaniQ geothermometry: rheological implications for the anatectic domain of the Araçuaí belt, eastern Brazil

2015/1/6
During the Neoproterozoic orogeny, the middle crust of the Araçuaí belt underwent widespread partial melting. At the regional scale, this anatectic domain is characterized by a progressive rotati...

Chlorite Geothermometry?—Contamination and Apparent Octahedral Vacancies
Analytical electron microscopy Chlorite Chlorite geothermometry
2011/12/29
The large contents of octahedral vacancies in published formulae of chlorite from hydrothermal systems and clastic sequences are shown to be largely caused by inclusion of other minerals. Verification...
Chlorite Polytype Geothermometry
Chlorite Diagenesis Geothermometry Low-grade metamorphism Polytypes
2011/12/29
Since the initial studies of chlorite polytypes, it has been suggested that the stability of the various polytypes may be a function of the temperature at which the mineral formed; however, few studie...
Chlorite minerals, found in a great variety of rocks and geological environments, display a wide range of chemical compositions and a variety of polytypes, which reflect the physicochemical conditions...
Illite/Smectite Geothermometry of the Proterozoic Oronto Group, Midcontinent Rift System
Diagenesis Illite/Smectite Mineralization Proterozoic Retrograde Thermal history
2011/12/29
Characterization of the Nonesuch Formation, middle unit of the Proterozoic Oronto Group, as a potential hydrocarbon source for the Lake Superior basin portion of the Midcontinent Rift system requires ...
Mixed-Layer Clay Geothermometry in the Wairakei Geothermal Field, New Zealand
Geothermal system Hydrothermal alteration Mixed-layer clays Reservoir permeability
2012/1/4
Mixed-layer clays of variable composition and structure occur in core samples from two drillholes (WK207 and WK210) drilled into the Te Mihi sector of the Wairakei geothermal field. These were identif...
