Consistent with this perspective, geochemical mapping made from orbit suggests the crust of mostly anorthosite. The Moon rock samples of the flood lavas that erupted onto the surface from partial melting in the mantle confirm the mafic mantle composition, which is more iron-rich than that of Earth. A video showing the anorthosite. Anorthosite is an intrusive igneous rock composed mainly of silicates called feldspar. It is an Earth rock that can be consi • Anorthosite was prominently represented in rock samples brought back from the Moon, and is important in investigations of Mars, Venus, and meteorites.

The moon rock would then be exported via huge vessels harnessing the rocks availability next to deep water. Anorthosite, type of intrusive igneous rock composed predominantly of calcium-rich plagioclase feldspar. All anorthosites found on Earth consist of coarse crystals, but some samples of the rock taken from the Moon are finely crystalline. Most anorthosites formed during Precambrian times.

This rock is NOT from the Moon but it is one of Earth's best equivalent to the " Genesis Rock" brought back by Apollo 15. Great medium-sized hand specimen.

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. Anorthosites, rocks composed almost entirely of plagioclase feldspar, are the oldest rocks on the Moon. They appear to have formed when feldspar crystallized and floated to the top of a global magma ocean that surrounded the Moon soon after it formed. 2009-09-10 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.

It have been investigated and classified by Anthony Irving at UWS (University of Washington at Seattle), and is It is a feldesphatic breccia: notice the impressive anorthosite clasts, embedded in the darker matrix of silicate minerals. This piece has an exact weight of 1.5 Schmidt, a geologist, was looking for anorthosite (a crystal mineral) to determine whether the moon had ever experienced volcanic activity - an important question.

The Moon highlands seem to be composed of anorthosite. We have both indirect and direct evidence for that.
