“Jake_M,” the first rock analyzed by the Alpha Particle X-ray Spectrometer instrument on the Curiosity rover, differs substantially in chemical composition from other known martian igneous rocks: It is alkaline (>15% normative nepheline) and relatively fractionated. Jake_M is compositionally similar to terrestrial mugearites, a rock type typically found at ocean islands and continental rifts. By analogy with these comparable terrestrial rocks, Jake_M could have been produced by extensive… 
Basalt–trachybasalt samples in Gale Crater, Mars
The ChemCam instrument on the Mars Science Laboratory (MSL) rover, Curiosity, observed numerous igneous float rocks and conglomerate clasts, reported previously. A new statistical analysis of

Alkali magmatism on Mars: an unexpected diversity
Despite an apparent north/south topographic dichotomy that formed >4.0 Ga, the young Martian meteorites (<2.4 Ga) and first-order remote sensing observations revealed a surface of Mars that is
Mineralogy and geochemistry of sedimentary rocks and eolian sediments in Gale crater, Mars_ A review after six Earth years of exploration with Curiosity
The Mars Science Laboratory Curiosity rover arrived at Mars in August 2012 with a primary goal of characterizing the habitability of ancient and modern environments. Curiosity was sent to Gale crater
Elemental Geochemistry of Sedimentary Rocks at Yellowknife Bay, Gale Crater, Mars
The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions during the early history of Mars.
The potassic sedimentary rocks in Gale Crater, Mars, as seen by ChemCam on board Curiosity
The Mars Science Laboratory rover Curiosity encountered potassium‐rich clastic sedimentary rocks at two sites in Gale Crater, the waypoints Cooperstown and Kimberley. These rocks include several
Geochemical diversity in first rocks examined by the Curiosity Rover in Gale Crater: Evidence for and significance of an alkali and volatile‐rich igneous source
The first four rocks examined by the Mars Science Laboratory Alpha Particle X‐ray Spectrometer indicate that Curiosity landed in a lithologically diverse region of Mars. These rocks, collectively
Potassium‐rich sandstones within the Gale impact crater, Mars: The APXS perspective
The Alpha Particle X‐ray spectrometer (APXS) on board the Curiosity rover at the Kimberley location within Gale crater, Mars, analyzed basaltic sandstones that are characterized by potassium


APXS of First Rocks Encountered by Curiosity in Gale Crater: Geochemical Diversity and Volatile Element (K and ZN) Enrichment
The Alpha Particle X-ray spectrometer (APXS) on the Curiosity rover in Gale Crater [1] is the 4th such instrument to have landed on Mars [2]. Along the rover's traverse down-section toward Glenelg
Volcanism on Mars controlled by early oxidation of the upper mantle
Detailed information about the chemical composition and evolution of Mars has been derived principally from the SNC (shergottite–nakhlite–chassignite) meteorites, which are genetically related
Petrogenesis of high‐phosphorous Wishstone Class rocks in Gusev Crater, Mars
[1] The Spirit rover has analyzed a wide variety of alkaline volcanic rocks in Gusev Crater. Among them are Wishstone Class tephrites with unusually high P2O5 (>5 wt %) abundances. To obtain the
Elemental Composition of the Martian Crust
Spacecraft data suggest that martian meteorites are not representative of older, more voluminous crust and prompt questions about their use in defining diagnostic geochemical characteristics and in constraining mantle compositional models for Mars.
Petrology and chemistry of MIL 03346 and its significance in understanding the petrogenesis of nakhlites on Mars
Abstract— Antarctic meteorite Miller Range (MIL) 03346 is a nakhlite composed of 79% clinopyroxene, ˜1% olivine, and 20% vitrophyric intercumulus material. We have performed a petrological and
Metasomatized Lithosphere and the Origin of Alkaline Lavas
It is concluded that melting of metasomatized lithosphere is a viable alternative to models of alkaline basalt formation by melting of recycled oceanic crust with or without sediment.
Upper mantle source for some hawaiites, mugearites and benmoreites
Chemical analyses of over seventy lavas or dykes containing spinel lherzolite inclusions of high pressure mineralogy, show that most host magmas are of alkali olivine basalt or basanite composition
Large‐ion lithophile element fractionation during the early differentiation of Mars and the composition of the martian primitive mantle
Abstract— Basaltic shergottites display a systematic decrease in K/Th, K/U, and K/La ratios with increasing K content. These trends are interpreted as mixing lines between relatively young martian
