Rocks like this make up much of the Highlands of the Moon, where feldspar produces the light color. Shortly after material gathered together to form the Moon, the outer Moon melted. Lunar anorthosite Anorthosite is a fascinating rock and sparks interest even among those who usually don’t care about rocks. The reason is simple. Anorthosite is often composed of mineral labradorite which is famous for an iridescent effect called labradorescence.

In general, lunar feldspathic meteorites tend to be more anorthosite-rich, and poorer in KREEP, than their Apollo equivalents. We present a new global survey of the purest anorthosite (PAN) rock using the Spectral Profiler onboard Kaguya. We found that PAN rocks are widely distributed over the Moon, including the Feldspath Anorthosite masses are relatively rare on Earth, and when they occur, they tend to be very old Precambrian rocks. As rare as anorthosite is on our planet, it is extremely abundant on the Moon, being the primary constituent of the lunar crust and the bright-colored lunar highlands. There is a layer of anorthosite in the subsurface of the central peak. Anorthosite sample returned by Apollo 15 (courtesy: NASA) KAGUYA's Multi-band Imager (MI) and Spectral Profiler (SP) investigate the distribution of minerals across the Moon by observing the reflected sunlight at the lunar surface.

Ohtake et al. (2009) The global distribution of pure anorthosite on the Moon. When the Earth was first forming, anorthosite was probably produced the same way it was on the Moon. The Earth, however, is much bigger, and its crust was more dynamic. Because of plate tectonics, which continually destroy and create the Earth’s surface, most of the anorthosite that existed has probably been processed into the Earth ’s interior. anorthosite on the moon.
2015-12-31 · Anorthosite is an intrusive igneous rock formed through the crystallization and accumulation of anorthite within a magma body. It is abundant on the Moon, and lunar anorthosites are believed to have accumulated on top of a magma ocean early in lunar history . A = >98% anorthosite (pure) B = 90-98% anorthosite C = <90% anorthosite Optical maturity index values > 0.6 mean the crater is fresh. Note that Copernicus is not fresh enough to be considered fresh.

However, there are numerous differences, nearly all associated with the lack of water and wind on the Moon. Typically, calcium-rich anorthosite deposits are small, irregular and contain too many impurities for commercial applications. The White Mountain ore body is geologically massive and homogeneous with no competitors. The only larger anorthosite occurance is on the moon, which is 384,000 km away. Anorthosite is essentially a variety of granite, arising as all granites do from the molten material of the Earths core and today it forms the heart of the geologically legendary South Harris igneous complex which provides some of Scotlands most impressive scenery. SUMMARY • Anorthosite is a phaneritic, intrusive igneous rock that contain more amount of plagioclase feldspar, nearly 100%.

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. Anorthosites on Earth are pretty old too, mostly from the Proterozoic Eon. Anorthosite is a plutonic rock just as granite and gabbro and it is usually associated with the latter. Types of rocks on the Moon: basalt, anorthosite, breccia, and “soil” (regolith).
But the supply of anorthosite samples from the Moon is limited. Fortunately, the rock can also be found on Earth. The giant impact hypothesis for the origin of the Moon points to the creation of a hot, young Moon, likely with a global magma ocean. Such a magma ocean would produce a flotation crust of plagioclase crystals, or an anorthositic crust. Early calculations of the expected anorthosite content of the lunar highlands crust did not match initial measurements of Apollo samples, and more recently have
The anorthosite body was formed as an accumulation of plagioclase crystals at the bottom of the magma chamber. Anorthosite can vary widely in color. An anorthosite complex in Wyoming yields anorthosite that is very dark gray, almost black.

Soil development on anorthosite [ edit ] In the Adirondack Mountains, soils on anorthositic rock tend to be stony loamy sand with classic podzol profile development usually evident.  anorthosite under a 300x microscope So valued is this moon rock that there were detailed plans to create a veritable space port on the east coast of Harris and to blast it out in vast quantities. 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.

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. 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. 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. 1993-07-01 occurrence of anorthosite on the Moon r equires a global ma gma body, referred t o as the 70 lunar magma ocean (LMO) (Yamamoto et al., 2012).
