Biconical reflectance, micro-Raman, and nano-FTIR spectroscopy of the Didim (H3-5) meteorite: Chemical content and molecular variations
Yeşiltaş, Mehmet; Kaya, M.; Glotch, T. D.; Brunetto, R.; Maturilli, A.; Helbert, J.; Ozel, M. E. (Wiley, 2020)The Didim meteorite contains multiple lithologies and clasts of different petrologic types in a single stone. A mixture of H5 clasts in an unequilibrated H3 host was previously observed in Didim, according to the initial ... -
Carbonaceous matter in the Saricicek meteorite
Yeşiltaş, Mehmet; Glotch, Timothy D.; Jaret, Steven; Verchovsky, Alexander B.; Greenwood, Richard C. (Wiley, 2019)As of today, the Saricicek (SC) meteorite is the newest howardite and the only confirmed fall among the 17 known howardites. In this study, we present isotopic, infrared, and Raman data on three distinct pieces of the SC ... -
Investigation of carbon in the Allan Hills A77278 meteorite via 2D and 3D Raman microspectroscopy
Yeşiltaş, Mehmet (Wiley, 2018)This paper reports the first Raman spectral and imaging data on the ordinary chondrite Allan Hills A77278 (ALHA77278) in two and three dimensions. Mineralogy in the ALHA77278 meteorite appears to be mainly silicates (olivine ... -
Investigation of carbonates in the Sutter's Mill meteorite grains with hyperspectral infrared imaging micro-spectroscopy
Yeşiltaş, Mehmet (Pergamon-Elsevier Science Ltd, 2018)Synchrotron-based high spatial resolution hyperspectral infrared imaging technique provides thousands of infrared spectra with high resolution, thus allowing us to acquire detailed spatial maps of chemical molecular ... -
MGS-TES Spectra Suggest a Basaltic Component in the Regolith of Phobos
Glotch, Timothy D.; Edwards, Christopher S.; Yeşiltaş, Mehmet; Shirley, Katherine A.; McDougall, Dylan S.; Kling, Alexander M.; Herd, Christopher D. K. (Amer Geophysical Union, 2018)Plain Language Summary The origins of the Martian moons Phobos and Deimos have been the subjects of considerable debate. Visible and near-infrared spectra of these bodies are dark and nearly featureless, with red slopes ... -
The Saricicek howardite fall in Turkey: Source crater of HED meteorites on Vesta and impact risk of Vestoids
Ünsalan, Ozan; Jenniskens, Peter; Yin, Qingzhu; Kaygısız, Ersin; Albers, Jim; Clark, David L.; Schmedemann, Nico (Wiley, 2019)The Saricicek howardite meteorite shower consisting of 343 documented stones occurred on September 2, 2015 in Turkey and is the first documented howardite fall. Cosmogenic isotopes show that Saricicek experienced a complex ... -
Three-Dimensional Raman Tomographic Microspectroscopy: A Novel Imaging Technique
Yeşiltaş, Mehmet; Jaret, Steven; Young, Jordan; Wright, Shawn P.; Glotch, Timothy D. (Amer Geophysical Union, 2018)Chemical constituents and their spatial distributions in terrestrial and extraterrestrial samples may provide clues to their formation histories and secondary processes they were subjected to. Most analytical tools are ...
