Journal ArticleDOI

TL;DR: The first map of variations in the abundances of thermal-neutron-absorbing elements across Mercury's surface has been derived from measurements made with the anti-coincidence shield on MESSENGER's Gamma-Ray Spectrometer (GRS) as mentioned in this paper.
Journal ArticleDOI
Geochemistry, mineralogy, and petrology of boninitic and komatiitic rocks on the mercurian surface: Insights into the mercurian mantle
Kathleen E. Vander Kaaden,Kathleen E. Vander Kaaden,Francis M. McCubbin,Larry R. Nittler,Patrick N. Peplowski,Shoshana Z. Weider,Elizabeth A. Frank,Timothy J. McCoy +7 more
TL;DR: In this article, a variation on the classical CIPW normative mineralogy calculation is used to constrain the potential mineralogy of Mercury's surface; the calculated silicate mineralogy is dominated by plagioclase, pyroxene, and olivine, with lesser amounts of quartz, and the range in surface compositions indicate that the rocks on the surface of Mercury are diverse and vary from komatiitic to boninitic.
Journal ArticleDOI
Observations, Meteorites, and Models: A Preflight Assessment of the Composition and Formation of (16) Psyche.

TL;DR: Observations of Psyche with data from meteorites and models for planetesimal formation are combined to produce the best current hypotheses for Psyche's properties and provenance.
Journal ArticleDOI
Chlorine on the surface of Mercury: MESSENGER gamma-ray measurements and implications for the planet’s formation and evolution
Larry G. Evans,Patrick N. Peplowski,Francis M. McCubbin,Timothy J. McCoy,Larry R. Nittler,Mikhail Yu. Zolotov,Denton S. Ebel,David J. Lawrence,R. D. Starr,Shoshana Z. Weider,Sean C. Solomon,Sean C. Solomon +11 more
TL;DR: In this paper, the MESSENGER Gamma-Ray Spectrometer was used to determine the surface abundance of chlorine in Mercury's northern hemisphere, and the derived Cl/Si mass ratio is 0.0057−±-0.001, which for an assumed Si abundance of 24.6% corresponds to 0.14−±−0.03% Cl.
Journal ArticleDOI
Constraints on the abundance of carbon in near-surface materials on Mercury: Results from the MESSENGER Gamma-Ray Spectrometer

TL;DR: In this article, the gamma-ray spectroscopy data from the MESSENGER Gamma-Ray Spectrometer (GRS) was used to constrain the C content of the surface of the Earth.
