متن کاملWeathering 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 کاملOxygen Isotopes of Al-rich Chondrules from Unequilibrated Ordinary Chondrites
Al-rich chondrules (ARCs) are a rare constituent of chondrites. They have relatively high bulk Al20 3 content(> 10 wt%), which is due to the presence of Al-rich phases, such as plagioclase, spinel, Al-rich glass etc. [1]. ARCs share some chemical and petrologic characteristics with Ca, Al-rich inclusions (CAis), and may represent a genetic link between ferromagnesian chondrules and CAis. Twelve...
متن کاملNi2As2O7 pyrochlore nanomaterial: Solid state synthesis, crystal structure determination, crystal phase growth study and physical properties
Nanostructured Ni2As2O7 semiconductor samples were synthesized by a solid state method among As2O3 and Ni(NO3)2.6H2O raw materials at 650 °C (S1) and 750 °C (S2) as reaction temperatures. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique and F...
متن کاملSynthesis and Crystal Structure Determination of Ag9FeS4.1Te1.9, the First Example of an Iron Containing Argyrodite
Ag9FeS4.1Te1.9 was prepared by solid state synthesis from stoichiometric amounts of the elements at 873 K. The compound forms gray crystals which are stable against air and moisture. The crystal structure was determined by X-ray diffraction from selected single crystals. Ag9FeS4.1Te1.9 crystallizes in the space group F4 ̅3m, a = 11.0415(7) Å, V = 1346.1(1) Å, and Z = 4 (powder data at 293 K). Th...
