GenderFail: The Queer Ethics of Dissemination
My research is centered upon my ongoing project GenderFail, a publishing and programming initiative featuring the perspectives of queer and trans people and people of color. GenderFail: The Queer Ethics of Dissemination is a collection of writings on queer collaboration, archiving as a collective act, and publishing as a site of queer community. The following text also illustrates the importance of creating and maintaining an intersectional platform as a non-binary white queer subject. I examine and define the role of “queer identity” in my own work while mapping the history of failure by white queers, including myself, in the of articulation of intersectionality. By understanding how intersectionality is important in a queer-focused collaborative practice, I seek to emphasize the messiness of citation, collaboration, and community in relation to my discursive uses of printed matter
The Mount Perkins block, northwestern Arizona: An exposed cross section of an evolving, preextensional to synextensional magmatic system
This is the published version. Reuse is subject to Society of Exploration Geophysicists terms of use and conditions.The steeply tilted Mount Perkins block, northwestern Arizona, exposes a cross section of a magmatic system that evolved through the onset of regional extension. New 40Ar/39Ar ages of variably tilted (0–90°) volcanic strata bracket extension between 15.7 and 11.3 Ma. Preextensional intrusive activity included emplacement of a composite Miocene laccolith and stock, trachydacite dome complex, and east striking rhyolite dikes. Related volcanic activity produced an ∼18–16 Ma stratovolcano, cored by trachydacite domes and flanked by trachydacite-trachyandesite flows, and ∼16 Ma rhyolite flows. Similar compositions indicate a genetic link between the stratovolcano and granodioritic phase of the laccolith. Magmatic activity synchronous with early regional extension (15.7–14.5 Ma) generated a thick, felsic volcanic sequence, a swarm of northerly striking subvertical rhyolite dikes, and rhyolite domes. Field relations and compositions indicate that the dike swarm and felsic volcanic sequence are cogenetic. Modes of magma emplacement changed during the onset of extension from subhorizontal sheets, east striking dikes, and stocks to northerly striking, subvertical dike swarms, as the regional stress field shifted from nearly isotropic to decidedly anisotropic with an east-west trending, horizontal least principal stress. Preextensional trachydacitic and preextensional to synextensional rhyolitic magmas were part of an evolving system, which involved the ponding of mantle-derived basaltic magmas and ensuing crustal melting and assimilation at progressively shallower levels. Major extension halted this system by generating abundant pathways to the surface (fractures), which flushed out preexisting crustal melts and hybrid magmas. Remaining silicic melts were quenched by rapid, upper crustal cooling induced by tectonic denudation. These processes facilitated eruption of mafic magmas. Accordingly, silicic magmatism at Mount Perkins ended abruptly during peak extension ∼14.5 Ma and gave way to mafic magmatism, which continued until extension ceased

The geology of the Canada del Oro headwaters, Santa Catalina Mountains, Arizona
Geologic mapping, with an emphasis on structure, was carried out in the region of the headwaters of the Canada del Oro. Major intrusive rock types delineated in the study area include the Oracle Granite, Leatherwood quartz diorite, granodiorite porphyry, Catalina granite, and Reef of Rock granite. Sedimentary rock types mapped in the area include the Younger Precambrian Apache Group, Cambrian Boisa Quartzite and Abrigo Formation, Devonian Martin Formation, and the Mississippian Escabrosa Limestone. Large wavelength synclines deform the Apache Group sedimentary rocks in the north and metamorphosed Paleozoic sedimentary rocks of Marble Peak in the south. The northwest-trending Geeseman Fault cuts across Oracle Granite, Leatherwood quartz diorite, and Catalina and Reef of Rock granites. Structural analysis indicates a Cretaceous(?) component of sinistral strike-slip displacement and a Tertiary component of dip-slip displacement, south block down. The Older Precambrian Oracle Granite is the oldest rock in the area. Tectonic quiescence is marked by the deposition of the Younger Precambrian and Paleozoic sediments. Subsequent intrusive events began in the Late Mesozoic ending with the Reef of Rock granite. Movements on the Geeseman Fault and other northwest-trending faults during Basin and Range time resulted in the formation of the down-dropped graben of the Canada del Oro valley.hydrology collectio

Results of Deep Drilling in the Western Moat of Long Valley California
Long Valley caldera has been explored for its potential geothermal resources for at least two decades. Unocal Geothermal drilled two deep test wells on the resurgent dome of the caldera during 1979. Neither of these wells encountered a deep, high temperature geothermal reservoir. The results from these wells and other geologic data focused exploration on the western caldera moat. Encouraging temperature gradient data in 1982 led to the drilling of a deep test well in 1985. That well, IDFU 44-16, encountered deep temperature reversals and a sequence of rocks unlike the previous penetrations on the resurgent dome. Evidently the well is still within the ring fracture system of the caldera and not within a central, upwelling, hydrothermal system which supplies the caldera’s discharge. 9 refs., 8 figs
