Scientist Mas Subramanian of Oregon State University, who made history a decade ago with the accidental discovery of the first new blue inorganic pigment in more than two centuries, is again pushing f...
Relationship between CAIs and chondrules: A case study of a compound chondrule from the Allende (CV3) meteorite
chondrule calcium-aluminium rich inclusion CV chondrite oxygen isotopes silicon isotopes
font style='font-size:12px;'>
2017/4/10
We report the mineralogy, petrology, major, minor and trace element geochemistry, O and Si isotopes of a complex
compound chondrule from the Allende meteorite. The chondrule contains zones of refract...

2017/4/11
Two homologous series of alkylpyridines (CnH2n–5N and CnH2n–7N) were identified in the methanol extract of the
Murchison meteorite by liquid chromatography/high-resolution mass spectrometry. The wide...
High-spatial resolution U–Pb dating of phosphate minerals in Martian meteorite Allan Hills 84001
U–Pb dating phosphates NanoSIMS Martian meteorites ALH 84001
font style='font-size:12px;'>
2017/4/11
Phosphate minerals, which are ubiquitous in terrestrial and extra-terrestrial rocks, are important carriers of trace elements,
including U and Th, which provide chronological information because of t...
Simple relationship between 26Al production rate and major elemental composition of meteorite samples
production rate 26Al terrestrial age howardite eucrite
font style='font-size:12px;'>
2017/4/11
Estimation of 26Al (half-life = 705 kyr) content at the time of meteorite fall is required to calculate the terrestrial age
of meteorites using the 26Al content. Previous studies (e.g., Cressy, 1971;...
