Professional Passions

Detailed petrographic (modal) analysis of igneous rocks

• briefly described in Warren et al (1989) and (1984), and in detail in Warren et al (in prep)

-- New techniques for modal analysis

-- extremely high level of documentation and accuracy

-- quantitative analysis for accessory minerals

Volcanic history and magmatic and structural evolution of Southwestern Nevada volcanic field (SWNVF)

-- single stratigraphic system for entire SWNVF

Warren (1983); Sawyer et al. (1994)

-- Magmatic evolution of SWNVF

Warren et al. (1989); Broxton et al. (1989); Farmer et al. (1991)

-- Structural evolution of SWNVF

Warren et al. (1985); Ferguson et al. (1994); Hudson et al. (1994)

Analytical geochemistry

-- technical director of EES XRF analytical system, operated by Emily Kluk

--Exceptional quality assurance, more than 30 rock standards routinely analyzed with samples

-- Analytical uncertainties calculated for analysis of all 20 elements in each sample using propagation of errors in 5 variables

-- Innovative data reduction using Loss on Ignition, which results in accuracy through an extreme range in rock compositions.

Present and Future Goals

• Publish "opus magnus", a relational database that contains the bulk of published and unpublished petrographic and geochemical analysis for SWNVF.

The database contains of the following information:

• 3100 mostly-unpublished, high-quality petrographic analyses (work mostly by Frank Byers, USGS)
• 1000 mostly-unpublished, highly documented petrographic analyses with trace mineral abundances (work by Rick Warren)
• 1700 mostly-unpublished Neutron Activation Analyses (mostly work by Rick Warren and Sammy R. Garcia of LANL)
• 1800 major-element analyses from numerous published and unpublished sources
• 1400 trace element analyses from numerous published and unpublished sources
• 36,000 mostly-unpublished analyses by electron microprobe (work mostly by Rick Warren)
• 400 mostly published radiometric dates, but including 110 unpublished Ar/Ar (high precision) dates by David Sawyer, USGS
• 16,000 individual mineral sizes used for petrographic analysis
• 600 mineralogical analyses by XRD, mostly published for Yucca Mountain
• 5000 layers in 200 wells that have stratigraphic unit, lithology, and alteration defined

• Write report to describe EES XRF analytical system with Emily C. Kluk.
• Write USGS monograph with David A. Sawyer to describe volcanic stratigraphy and magmatic evolution of SWNVF.
• Apply detailed petrographic analytical techniques to units of the Jemez Volcanic field, NM, with David E. Broxton.
• Develop model to represent important geologic features of SWNVF in 3-D with Gregory L. Cole.
