The most characteristic infrared (IR) spectral shape of shock-annealed sub-grained pyroxene was identified: the strongest peak occurs at 860 cm−1 with a smaller shoulder at 837−840 cm−1, and small bands are at 686, 635−638, and 1,044−1,050 cm−1. The appearance of forbidden bands in pyroxene and shift of band positions to a lower wave number in olivines clearly demonstrate the crystal lattice disordering due to shock metamorphism. The shock annealing produced mixed dark melt along fractures, which consists of feldspar−pyroxene and olivine−pyroxene melt. The dark shock melt at sub-grain boundaries of shocked pyroxenes and along fracture of pyroxenes is characterized by elevated Ca, Na, and Al content relative to its environment, detected by element mapping. So far, shock deformation of pyroxene and olivine was not studied by IR spectroscopy; this method has turned out to be a powerful tool in identifying the mixed composition of shock melt minerals. Further study of shock annealing of minerals, together with the context of shock melting at sub-grain boundaries, will provide a better understanding of the formation of high P–T minerals. http://akademiai.com/doi/pdf/10.1556/24.60.2017.007}, year = {2017}, eissn = {1789-3348}, pages = {173-200}, orcid-numbers = {Gyollai, Ildikó/0000-0001-8576-0196} } @article{MTMT:3130280, title = {Analyzing Raman – Infrared spectral correlation in the recently found meteorite Csátalja}, url = {https://m2.mtmt.hu/api/publication/3130280}, author = {Kereszturi, Ákos and Gyollai, Ildikó and Kereszty, Zs and Kiss, Klaudia and Szabó, Máté Zoltán and Szalai, Zoltán and Ringer, Marianna and Veres, Miklós}, doi = {10.1016/j.saa.2016.10.012}, journal-iso = {SPECTROCHIM ACTA A}, journal = {SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY}, volume = {173}, unique-id = {3130280}, issn = {1386-1425}, year = {2017}, eissn = {1873-3557}, pages = {637-646}, orcid-numbers = {Gyollai, Ildikó/0000-0001-8576-0196; Szalai, Zoltán/0000-0001-5267-411X} } @CONFERENCE{MTMT:3012004, title = {Luminescence Spectroscopical Properties of Plagioclase Particles from Hayabusa Sample Return Mission}, url = {https://m2.mtmt.hu/api/publication/3012004}, author = {Gucsik, Arnold and Nishido, H and Ninagawa, K and Kereszturi, Ákos and Nakamura, T and Tsuchiyama, A and Jäger, C and Ott, U and Kayama, M}, booktitle = {46th Lunar and Planetary Science Conference}, unique-id = {3012004}, year = {2015} } @article{MTMT:3088020, title = {A new classification of Nyirábrany, an ordinary chondrite from Hungary}, url = {https://m2.mtmt.hu/api/publication/3088020}, author = {Mészáros, M and Kereszturi, Ákos and Ditrói-Puskás, Zuárd}, doi = {10.5277/met140102}, journal-iso = {METEORITES}, journal = {METEORITES}, volume = {3}, unique-id = {3088020}, issn = {2299-0313}, year = {2014}, eissn = {2299-1220}, pages = {17-31} } @article{MTMT:2149903, title = {Shock and thermal annealing history of the ALH 77005 Martian meteorite: A micro-Raman spectroscopical investigation}, url = {https://m2.mtmt.hu/api/publication/2149903}, author = {Nagy, S and Józsa, Sándor and Gucsik, Arnold and Bérczi, Szaniszló and Ninagawa, K and Nishido, H and Veres, Miklós and Kereszturi, Ákos and Hargitai, Henrik}, doi = {10.1556/CEuGeol.55.2012.1.3}, journal-iso = {CENT EUR GEOL}, journal = {CENTRAL EUROPEAN GEOLOGY}, volume = {55}, unique-id = {2149903}, issn = {1788-2281}, abstract = {We studied optical microscopic and micro-Raman spectroscopic signatures of shocked olivine from the ALH 77005 Martian meteorite sample. The purpose of this study is to document pressure and temperature-related effects in olivine over the entire sample, which can aid in understanding structural changes due to shock metamorphism and the post-shock thermal annealing processes of lherzolitic Martian meteorites. According to the optical microscope observations, three areas may be discernible in olivine of the ALH 77005 in the vicinity of the melt pocket. The first area is the thermally undisturbed part of a grain, which contains a high density of shock-induced planar microdeformations such as Planar Deformation Features (PDFs) and Planar Fractures (PFs). Compared to the first area, the second area shows less shock-induced microstructures, while the third area is a strongly recrystallized region, but not formed from a melt.A common Raman spectral feature of these olivines is a regular doublet peak centered at 823 and 852 cm-1; additionally, two new peaks at 535 and 755 cm -1 appear in the weakly annealed transition zones.}, keywords = {microstructure; annealing; recrystallization; raman spectroscopy; temperature effect; olivine; high pressure; deformation mechanism; observational method; P-T conditions; micro-Raman spectroscopy; SHOCK METAMORPHISM; MARTIAN METEORITE; high pressure zeta phase}, year = {2012}, eissn = {1789-3348}, pages = {33-48}, orcid-numbers = {Józsa, Sándor/0000-0001-8219-0044; Hargitai, Henrik/0000-0001-6563-6921} } @book{MTMT:2568362, title = {Célpont a Föld? - Kisbolygók a láthatáron}, url = {https://m2.mtmt.hu/api/publication/2568362}, isbn = {9632067746}, author = {Kereszturi, Ákos and Sárneczky, Krisztián}, publisher = {Hungarian Astronomical Association}, unique-id = {2568362}, year = {2003} }
