Meteoritics &Planetary Science, EarlyView.Abstract Apatite is often the most rare earth element (REE)‐enriched mineral in chondritic meteorites. REE enrichment and fractionation levels in apatite grains can give insight into the aqueous fluids in which they formed and the conditions prevailing within the host body. In this study, we applied synchrotron X‐ray fluorescence (SXRF) spectroscopy to

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ<sup>15</sup>N Integrity of Nitrogen-Poor Samples. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

Shock effects in iron meteorites – Morasko and Jankowo Dolne meteorites [PDF]
, 2009 Iron meteorites are the only ones to be linked with terrestrial impact craters. As studies show, over half of all iron meteorites shows signs of being shocked some time in their history to pressures over 130 kb. This paper is a short review of main shock

Photochemistry and Photobiology, EarlyView.Thin solid films of pure glycine or alanine (thicknesses ranging from 10 to 700 nm) were prepared on MgF2 windows using a vacuum sublimation/recondensation method. VUV‐UV spectroscopy of these films enabled us to characterize new absorption cross sections for glycine and alanine for VUV‐UV radiations between 120 and 300 nm.

Meteorites and the Antarctic ice sheet [PDF]
, 1986 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.

Radon on Mars and the Moon derived from Martian and lunar meteorites
Scientific ReportsThe radioactive gas radon-222, a fluid and aerosol tracer in Earth’s lithosphere and atmosphere, can also reveal subtle rock physics processes in extraterrestrial environments, such as those involving water, but remains poorly constrained in planetary ...
