Constraints on Martian differentiation processes from RbSr and SmNd isotopic analyses of the basaltic shergottite QUE 94201
TLDR
In this article, isotope dilution data of the shergottite meteorite QUE 94201 has been used to identify a leachable crustal component in the meteorite, which can affect the isochrons by selectively altering the isotopic systematics of the leachates and some of the mineral fractions.About:

Constraints on the depths and temperatures of basaltic magma generation on Earth and other terrestrial planets using new thermobarometers for mafic magmas
TL;DR: In this article, a thermobarometer based on magma Si and Mg contents was used to estimate the pressures and temperatures of basaltic magma generation on Earth and other terrestrial planets.

Ages and Geologic Histories of Martian Meteorites
TL;DR: In this article, the authors review the radiometric ages of the 16 currently known Martian meteorites, classified as 11 shergottites (8 basaltic and 3 lherzolitic), 3 nakhlites (clinopyroxenites), Chassigny (a dunite), and the orthopyroxensite ALH84001.

TL;DR: In this paper, the authors used the Hf-W systematics of meteoritic and planetary samples to provide firm constraints on the chronology of the accretion and earliest evolution of asteroids and terrestrial planets and lead to the following succession and duration of events in the earliest solar system.

TL;DR: The early views of the Moon manifested in mythology and art throughout the world were primarily tied to lunar and terrestrial cycles and the relationships between the Sun and the Moon as mentioned in this paper, and many of these early views were associated with the violent or catastrophic events in which the Moon was expunged from the Earth.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.
