Results of Rock Magnetic and Mineralogical Analyses of Ultramafic Cores from the Oman Drilling Project
<p>This dataset comprises of original rock magnetic data, microscope images, EPMA data, and EDS reports used for analysis of serpentinized ultramafic cores drilled during the Oman Drilling Project (OmanDP).</p> <p>Rock magnetic experiments have been performed onboard D/V Chikyu and in a shielded facility located at the University of Iceland. Results included in the dataset are as follows: Mass susceptibility, Natural remanence before and after alternating field (AF) and thermal demagnetization, and thermomagnetic measurements. </p> <p>Microscopic images and EDS reports are the results of backscatter electron microscopy that was held at Seoul National University with a JEOL JSM-7100F scanning electron microscope. EPMA results were produced using the JXA-8530F electron probe micro-analyzer at the National Center for Inter-University Research Facilities (NCIRF) of Seoul National University (SNU).</p> <p> </p>
Huge variation in H2 generation during seawater alteration of ultramafic rocks: Dataset
<p>Dataset associated with the <em>Geochemistry, Geophysics, Geosystems</em> paper, "Huge variation in H2 generation during seawater alteration of ultramafic rocks"</p>
Thermal emission spectra of ultramafic to felsic rocks
<p>This data set contains two files. One file contains thermal emission spectra of 10 rock samples. Data were collected at Arizona State University in the early 2000's. Most samples were purchased from Ward's. The other file contains the same spectra, degraded to the spectral bandpasses of the Mars Odyssey Thermal Emission Imaging System (THEMIS). All lab spectra were measured from rock hand samples (not particulate samples).</p> <p>These data were shown in: </p> <p>Rogers, A. D. and H. Nekvasil (2015), Feldspathic rocks on Mars: Compositional constraints from infrared spectroscopy and possible formation mechanisms, Geophys. Res. Lett., 42, 2619-2626, doi: 10.1002/2015GL063501.</p> <p>Most rocks are from the Ward's North American Rocks collection. https://www.wardsci.com/store/product/8869973/classic-north-american-rock-collection. </p> <p>The xaxis for the spectra at lab resolution is in units of wavenumber (cm^-1).</p> <p>The xaxis for the spectra at THEMIS resolution is in units of wavelength (microns).</p>
