material (ORM) on the Moon, possibly from both the lower crust and the upper mantle [Yamamoto et al., 2010]. In addition,multispectralobservationsbytheMultibandImager (MI) on board Kaguya revealed the existence of the purest anorthosite(PAN)[Ohtakeetal.,2009],providingimportant information on the primordial lunar crust. However, the Anorthosite. Found on both the moon and the Earth, anorthosite is an igneous rock primarily comprised of plagioclase feldspars. The name of the rock stems from the Greek an and orthos, which together mean “not upright,” a reference to the slanting form of the plagioclase crystals it contains.

The Moon is currently receding from the Earth by a few centimetres every year and will eventually be free of Earth's gravitational pull if the Moon's Pink Mineral--- Remote sensing detections of pink spinel anorthosite are compared with sample analyses and experimental results to learn more about the lunar crust.

Written by Linda M. V. Martel and G. Jeffrey Taylor Hawai'i Institute of Geophysics and Planetology Anorthosite masses are relatively rare on Earth, and when they occur, they tend to be very old Precambrian rocks.

Closer view of the Anorthosite at Stop 1. Note the tiny garnet in the center. The garnets were rare at this stop but more common at other stops. 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.

Lunar anorthosite • Probably formed the primitive lunar crust. • It consist of highly calcic plagioclase with It is middle Proterozoic in age. The Apollo astronauts brought a very similar anorthosite back from the moon. This anorthosite was intruded into a previously 7 Oct 2019 (1970) Lunar anorthosites and a geophysical model of the moon.

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. Mountain anorthosite (aka GreenSpar) would be useful as a mechanical simulant for testing of systems and components bound for the Moon.

This rock type still exists today and makes up the lunar highlands, which is the lighter-colored part of the moon visible from Earth. Anorthosite is not nearly as common here as it is on the Moon. Anorthosites on the Moon are extremely old, almost as old as the Moon itself.

This particular sample is nearly pure Early calculations of the expected anorthosite content of the lunar highlands crust did not match initial measurements of Apollo samples, and more recently have 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 17 Feb 2013 grains in lunar anorthosites thought to sample the primary crust, obtained crystallization of the lunar magma ocean than a dry moon scenario A lunar structural model is proposed in which a 25-kilometer anorthosite crust, produced by magmatic fractionation, floats on denser gabbro.
