(mineralogy) A plagioclase feldspar, the final member of the Albite-Anorthite solid solution series. Anorthite is very rare on Earth, but abundant in moon rocks.

Making pink spinel anorthosite requires formation of a lot of Mg-Al spinel, usually not particularly abundant in lunar samples. It has to crystallize in sufficient quantity or accumulate in a magma body. The papers led by Prissel and Gross report high-temperature experiments to examine the problem from the lunar surface to the base of the crust.

Close up view of one of the large plagioclase crystals at Stop 1. Note the diagnostic striations! Parts of this crystal appear iridescent making me believe it is The REE distribution pattern of lunar anorthosites, relative to ordinary chondrites, has a positive Eu anomaly. On the assumption that (i) the lunar composition is 3 May 2020 From Earth, lunar anorthosite is visible as the light-colored, highly reflective parts of the Moon's surface known as the lunar highlands.

Anorthosite moon

The “giant impact” scenario ha s 71 Seen from the Earth, the Moon's surface appears bright with distinct, darker areas. The bright regions form a rugged terrain, heavily marked with circular meteorite impact craters known as the lunar highlands. We now know that the highlands are made of rocks called anorthosite and polymict breccia. Recent near-infrared spectra of the Moon have delineated regions where spinel is the only ferromagnesian mineral; the rock is inferred to be spinel anorthosite.

• They are mainly classified as Proteroic anorthosite, Archean anorthosite, Lunar anorthosite and Layered anorthosite. Anorthite is the calcium endmember of the plagioclase feldspar mineral series.

That sample, nicknamed the Genesis Rock, sample number 15415, was an anorthosite, a piece of the moon’s primordial crust. Geologists, hoping to learn more about the moon and its origins, selected the Hadley-Apennines landing site for precisely this reason.

Olivine, amphibole, ilmenite, magnetite, and spinel are also sometimes present. The term anorthosite, from Frenc anorthose (term for plagioclase) was coined by Sterry Hunt.

The physical-chemical aspects of anorthosite formation are investigated, and the early stages of the evolution of the earth and moon are examined on the basis of a comparison of terrestrial and lunar anorthosites.

2017-06-18 1970-04-25 Lunar anorthosite is a major rock of the lunar highlands, which formed as a result of plagioclase-floatation in the lunar magma ocean (LMO). Constraints on the sufficient conditions that resulted in the formation of a thick pure anorthosite (mode of plagioclase >95 vol.%) is a key to reveal the early magmatic evolution of the terrestrial planets.

Introduction: A major unresolved question is whether there is an enrichment in plagioclase in the lunar crust. If a magma ocean once existed on the Moon, an anorthositic crust should have been formed by plagioclase floatation. Therefore, it is important to determine the distribution and modes of occurrence of anorthosite on the lunar surface. We have been conducting remote sensing studies of
