TL;DR: In this article, the MESSENGER images from the MRS spacecraft show that ~27% of Mercury's surface is covered by smooth plains, the majority of which are interpreted to be volcanic in origin, suggesting high temperatures and high degrees of partial melting in magma source regions persisted through most of the duration of smooth plains formation.

Radioactive Elements on Mercury’s Surface from MESSENGER: Implications for the Planet’s Formation and Evolution
Patrick N. Peplowski,Larry G. Evans,Steven A. Hauck,Timothy J. McCoy,William V. Boynton,J. J. Gillis-Davis,Denton S. Ebel,John O. Goldsten,D. K. Hamara,David J. Lawrence,Ralph L. McNutt,Larry R. Nittler,Sean C. Solomon,Edgar A. Rhodes,Ann L. Sprague,R. D. Starr,Karen R. Stockstill-Cahill +16 more
TL;DR: Gamma-ray emission from the surface of Mercury indicates that the planet accreted from relatively volatile-enriched material, consistent with widespread volcanism shortly after the end of late heavy bombardment 3.8 billion years ago and limited, isolated volcanic activity since.

Major-Element Abundances on the Surface of Mercury: Results from the MESSENGER Gamma-Ray Spectrometer
Larry G. Evans,Patrick N. Peplowski,Edgar A. Rhodes,David J. Lawrence,Timothy J. McCoy,Larry R. Nittler,Sean C. Solomon,Sean C. Solomon,Ann L. Sprague,Karen R. Stockstill-Cahill,R. D. Starr,Shoshana Z. Weider,William V. Boynton,D. K. Hamara,John O. Goldsten +14 more
TL;DR: In this paper, the gamma-ray and X-ray measurements obtained by the MESSENGER spacecraft have been analyzed to determine the abundances of the major elements Al, Ca, S, Fe, and Na on the surface of Mercury.
Journal ArticleDOI
Evidence for water ice near Mercury's north pole from MESSENGER Neutron Spectrometer measurements.
David J. Lawrence,W. C. Feldman,John O. Goldsten,Sylvestre Maurice,Patrick N. Peplowski,Brian J. Anderson,David Bazell,Ralph L. McNutt,Larry R. Nittler,Thomas H. Prettyman,D. J. Rodgers,Sean C. Solomon,Sean C. Solomon,Shoshana Z. Weider +13 more
TL;DR: MESSENGER neutron data reported by Lawrence et al. now confirm that the primary component of radar-reflective material at Mercury's north pole is water ice, and spacecraft data and a thermal model show that water ice and organic volatiles are present at Mercury’s north pole.
Journal ArticleDOI

TL;DR: In this article, the major-element composition of the surface of Mercury was mapped from orbital MESSENGER X-Ray Spectrometer measurements, and the results revealed highly variable compositions (e.g., Mg/Si and Al/Si range over 0.1 − 0.8 and 0.4, respectively).
