Digital elevation model of the lava dome in the crater of Mount St. Helens, July 18, 1986 Digital elevation model of the lava dome in the crater of Mount St. Helens, July 18, 1986
The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is that the May 18 eruption marked the beginning of a period of eruptive activity that lasted through 1986. Beginning in October 1980, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most...

Geochemistry and mineralogy of mill tailings from the Ducktown mining district, Tennessee, USA Geochemistry and mineralogy of mill tailings from the Ducktown mining district, Tennessee, USA
These .csv files contain data on the bulk mineralogy and geochemistry of tailings samples from the Ducktown volcanogenic massive sulfide mining district in Tennessee, USA. The reported geochemistry was collected using inductively-coupled plasma optical emission spectroscopy/mass spectrometry (ICP-OES/MS), wavelength-dispersive X-ray fluorescence (WDXRF), lead fire assay-inductively...
Geochemistry, olivine chemistry, microXRF chemical maps, and isotope geochemistry of komatiitic volcanic rocks and U-Pb geochronology of metasedimentary rocks from the Bradley Peak and South Pass greenstone terranes, Wyoming Province Geochemistry, olivine chemistry, microXRF chemical maps, and isotope geochemistry of komatiitic volcanic rocks and U-Pb geochronology of metasedimentary rocks from the Bradley Peak and South Pass greenstone terranes, Wyoming Province
Bradley Peak and South Pass are two ca. 2.7 Ga greenstone terranes in the Archean Wyoming Province, USA that contain mafic-ultramafic metavolcanic rocks. This dataset contains five Comma Separated Value (CSV) files of tabular data, a data dictionary for tabular data (Data_Dictionary.csv), a shapefile with sample locations, and microXRF images. Wholerock_geochemistry.csv includes whole...
