Radiocarbon datings of Yamato meteorites [PDF]
The terrestrial ages of five Yamato Meteorites were measured by the content of cosmic-ray-produced carbon-14. Three Yamato Meteorites Y-74013, Y-74097, and Y-74136, which are all diogenites, were found at sites from one to two kilometers apart from each ...

First disk-resolved spectroscopy of (4) Vesta
, 2009 Vesta, the second largest Main Belt asteroid, will be the first to be explored in 2011 by NASA's Dawn mission. It is a dry, likely differentiated body with spectrum suggesting that is has been resurfaced by basaltic lava flows, not too different from the

Prebiotic Phosphorylation Reactions on the Early Earth
Challenges, 2014 Phosphorus (P) is an essential element for life. It occurs in living beings in the form of phosphate, which is ubiquitous in biochemistry, chiefly in the form of C-O-P (carbon, oxygen and phosphorus), C-P, or P-O-P linkages to form life. Within prebiotic

Carbon reservoirs on Mars: Constraints from Martian meteorites [PDF]
, 2003 We have measured the abundance and stable isotopic composition of magmatic carbon extracted from a suite of shergottites. The results confirm previous findings that primordial carbon on Mars is isotopically lighter than that of the ...

The Maribo CM2 meteorite fall - survival of weak material at high entry speed
, 2019 High entry speed (> 25 km/s) and low density (< 2500 kg/m3) are two factors that lower the chance of a meteoroid to drop meteorites. The 26 g carbonaceous (CM2) meteorite Maribo recovered in Denmark in 2009 was delivered by a superbolide observed by ...

Meteorites and the Antarctic ice sheet [PDF]
The majority of the meteorite finds were located in the Allan Hills site. All the expected goals involving the recovery of rare or previously unknown types of meteorites, and even the recovery of lunar ejecta, were realized.

Lithium Isotopic Analysis of Spodumene by Secondary Ion Mass Spectrometry
Rapid Communications in Mass Spectrometry, Volume 40, Issue 13, 15 July 2026.ABSTRACT Rationale Lithium (Li) stable isotopes can provide insight into fluid–rock interaction and magmatic differentiation. Therefore, it is essential to develop an accurate and precise method to determine the Li isotope signature in spodumene.
