Mineralogical Evolution of Meteorites FRAGMENTS FROM THE BEGINNING
نویسنده
چکیده
As Earth evolved over the last 4.5 billion years, its mineralogy changed. As we peer back through Earth’s history, it seems logical to think that our lens would grow increasingly fogged and our light ever more dim. How do we see beyond the oldest preserved rocks and minerals, after billions of years of volcanism, plate tectonics, and weathering? How do we see past the Moon-forming collision, which would have melted the early Earth? Where is the starting point for the mineralogical evolution of Earth and the other terrestrial planets?

Weathering of Ordinary Chondrites from the Atacama Desert, Chile: First Results from Mössbauer Spectroscopy
The lunar meteorites have valuable informations for understanding the evolution of the Moon’s crust, because each meteorite may potentially provide a new insight into the thermal history of unexplored regions of the Moon. In spite of their scientific interests, chronological studies of Very-Low-Ti (VLT) basaltic meteorites have not be well understood, since the most VLT basalt meteorites are br...
متن کاملExploring the Mineralogical Diversity of Hed Meteorites with Microimaging Vswir Spectroscopy
Introduction: We used visible-short wavelength infrared (VSWIR) imaging spectroscopy to survey the spectral diversity of the howardite, eucrite, and diogenite (HED) meteorite suite at 80-μm/pixel spatial scale. This group of meteorites is widely believed to originate from the asteroid Vesta. Our goal in this work is to contribute to understanding the petrologic diversity of the HED suite and th...

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 کاملSystematics and Evaluation of Meteorite Classification
Classification of meteorites is largely based on their mineralogical and petrographic characteristics and their whole-rock chemical and O-isotopic compositions. According to the currently used classification scheme, meteorites are divided into chondrites, primitive achondrites, and achondrites. There are 15 chondrite groups, including 8 carbonaceous (CI, CM, CO, CV, CK, CR, CH, CB), 3 ordinary ...
متن کاملGeological History of Asteroid 4 Vesta: The “Smallest Terrestrial Planet”
The asteroid 4 Vesta is the only known differentiated asteroid with an intact internal structure, probably consisting of a metal core, an ultramafic mantle, and a basaltic crust. Considerable evidence suggests that the HED meteorites are impact ejecta from Vesta, and detailed studies of these meteorites in terrestrial laboratories, combined with ever more sophisticated remote sensing studies of...
