Petrologic Characteristics of the Lunar Surface [PDF]

open access: yesScientific Reports, 2015
AbstractPetrologic analysis of the lunar surface is critical for determining lunar formation and evolution. Here, we report the first global petrologic map that includes the five most important lunar lithological units: the Ferroan Anorthositic (FAN) Unit, the Magnesian Suite (MS) Unit, the Alkali Suite (AS) Unit, the KREEP Basalt (KB) Unit and the ...

Fe and Mg Isotope Compositions Indicate a Hybrid Mantle Source for Young Chang’E 5 Mare Basalts

open access: yesThe Astrophysical Journal Letters, 2023
The Chang’E 5 (CE-5) samples represent the youngest mare basalt ever known and provide an access into the late lunar evolution. Recent studies have revealed that CE-5 basalts are the most evolved lunar basalts, yet controversy remains over the nature of ...

Petrology of ALHA81005, the first lunar meteorite

open access: yesGeophysical Research Letters, 1983
Petrography and mineral compositions show that ALHA81005 is a lunar highland regolith breccia and is the first known lunar meteorite. Lithic clasts are abundant and most are members of the anorthosite‐norite‐troctolite highland suite. Plagioclase compositions in lithic clasts and single grains are calcic (An94‐98).

Paired lunar meteorites MAC88104 and MAC88105: A new “fan” of lunar petrology

open access: yesGeochimica et Cosmochimica Acta, 1991
To determine the chemical characteristics of the MAC88104/5 meteorite six thin sections and three bulk samples were analyzed by electron microprobe and instrumental neutron activation. It is concluded that this meteorite is dominated by lithologies of the ferroan anorthosite suite and contains abundant granulitized highland clasts, devitrified glass ...

The Moon’s Early Magmatic Activities: From the Perspective of Lunar Alkali-Suite and Mg-Suite Samples

open access: yesSpace: Science & Technology
This review places emphasis on ancient lunar nonmare igneous samples alkali-suite and Mg-suite. The material on mineralogy and petrology of the Mg-suite presented here draws from “Lunar samples” by Papike et al.

Mineralogy, petrology, and geochemistry of the lunar samples [PDF]

open access: yesEos, Transactions American Geophysical Union, 1971
On July 24, 1969, the first extraterrestrial samples, with the exception of meteorites, were returned to earth by Apollo 11. Since then these samples and the samples returned by Apollo 12 have been subjected to scientific investigations by hundreds of scientists from many countries.

Microspherules Formed by Lightning Strikes

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.
