Petrology and geochemistry of whole rock of Shahdad meteorites
In this study, meteorite pieces, with total weight of 259 grams, have been studied which is not listed in the world bulletin of meteorites. In order to classify these samples, after preparing microscopic thin sections and performing accurate petrography, using geochemical data of the major elements and trace elements of whole rock, obtained from XRF and ICPMS methods in Zarazma company’s labora...
متن کاملComplementary Stxm and Confocal Raman Imaging of Murchison
Introduction: Scanning transmission X-ray mi-croscopy (STXM) and confocal Raman imaging have been utilized on a sample of the Murchison CM2 meteorite in order to examine the structure and composition of carbonaceous material with a minimal degree of alteration due to sample preparation. The resulting complementary data set shows minute variation in car-bonaceous material crystallinity proximal ...
متن کاملConstraints on Mapping Source Regions of Martian Meteorites and the Distribution of Pyroxene on Mars: Ir Microspectroscopy of Pyroxene in Shergottites
Introduction: The surface mineralogy of Mars is constrained by spectral and chemical data from orbiters and landers. One technique for determining lithologies is thermal emission spec-troscopy. Virtually the entire surface of Mars has been mapped using either the TES [1] or THEMIS [2] instruments and the Mini-TES has made in situ measurements [e.g. 3]. These data have been used to try and find ...
متن کامل2013 Vicência Meteorite Found in Brazil: Preliminary Classification Efforts Based on Traditional Approaches and Cathodoluminescence (CL) Maps
A meteorite fall took place on September 21, 2013 in a tiny village called Vicência (also known as Vila da Borracha), located at Brazil’s northeast region, more specifically on the northwest of Pernambuco State. The meteorite almost struck a man (Mr. Adeildo) who noticed that one of the rock sides was still warm. The meteorite is now at the Rio de Janeiro National Museum for petrological classi...
متن کاملCRYSTAL SIZE DISTRIBUTION ANALYSIS OF NEW NAKHLITES AND LOS ANGELES: HOW DO THEY COMPARE WITH SNCs
Introduction: Crystal size distribution (CSD) analysis is a useful technique for quantifying textural information and linking petrographic texture to original crystallization conditions [1]. In previous studies we have conducted CSD analyses of multiple thin sections of nakhlite meteorites [2], and several basaltic and mixed shergottites [3,4]. Based on results of these analyses, we derived cry...
