what is the composition of lunar meteorites?

Its whole rock composition based on instrumental neutron activation analysis and electron microprobe analysis on fused glass beads indicates highly feldspathic source lithologies (3.5 wt% FeO, 28.8 wt% Al 2 O 3 ) with a magnesian character (mol% Mg/[Mg + Fe] = 77) and a low KREEP (potassium, rare-earth elements, ...

Moon rock or lunar rock is rock that is found on the Earth's Moon including lunar material collected during the course of human exploration of the Moon, or rock that has been ejected naturally from the Moon's surface (and which has then landed on the Earth as meteorites).

The core is surrounded by a silicate mantle that formed many of the tectonic and volcanic features on the planet, but now appears to be dormant. Besides silicon and oxygen, the most abundant elements in the Martian crust are iron, magnesium, aluminum, calcium, and potassium.

What is moondust made of? Almost half is silicon dioxide glass created by meteoroids hitting the moon. These impacts, which have been going on for billions of years, fuse topsoil into glass and shatter the same into tiny pieces.

Beneath its thin coating of crushed rock, the Moon has three layers—a crust, a mantle, and a core. As on Earth, the crust is the outermost layer. It averages about 70 kilometers (about 40 mi) thick and contains the least dense type of rock. Beneath the crust is a thick mantle that makes up most of the Moon's volume.

The asteroids that are nearest the Sun are mostly made of carbon, with smaller amounts of nitrogen, hydrogen and oxygen, while the ones further away are made up of silicate rock. Silicates are very common on Earth and in the Solar System.

Asteroids are made of rock, metals and other elements. Some even contain water, astronomers say. Asteroids that are mostly stone sometimes are more like loose piles of rubble. Asteroids that are mostly iron are more, well, rock-solid.

Iron is mineral that can be found in plants, animals, soil, air, water, meteorites, and rocks, including ones found on the surface of the moon. ... Iron is a metal; in fact, people with too much iron in their bodies can set off metal detectors.

Comets are large bodies made from rock, ice, and frozen gas, asteroids are made of rocks and minerals, meteoroids are made of rock and space debris. Moons are objects that revolve around planets, while comets obit around the sun and asteroids orbit between the sun and Jupiter, in the Asteroid Belt.

The composition of the Moon is much like that of the Earth. Its rocks are similar to Earth rocks and contain many but not all of the same minerals. However, the Moon has no atmosphere, it shows no trace of past or present life, and its rocks contain no water. The Moon rocks show that the lunar surface is very ancient.

Fresh White Craters, the brightest things on the Moon. Fresh white impact craters are the most recent impacts on the Moon. Anything less than a billion years old (which means it is from the current Copernican era), is considered young in lunar terms.

The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase (KAlSi3O8), Albite (NaAlSi3O8) and Anorthite (CaAl2Si2O8). Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements.

The lunar soil consists of three basic components: (1) rock fragments, (2) mineral grains and (3) glass particles. The composition of these three basic components varies considerably from one site to another, depending upon the nature of the bedrock.

There are three major types of meteorites: the "irons," the "stonys," and the stony-irons. Although the majority of meteorites that fall to Earth are stony, most of the meteorites discovered long after they fall are irons. Irons are heavier and easier to distinguish from Earth rocks than stony meteorites.

Composition of Olivine Olivine is the name given to a group of silicate minerals that have a generalized chemical composition of A2SiO4. In that generalized composition, "A" is usually Mg or Fe, but in unusual situations can be Ca, Mn, or Ni.

Meteorites are usually categorized as iron or stony. As the name implies, iron meteorites are composed of about 90 percent iron; stony meteorites are made up of oxygen, iron, silicon, magnesium and other elements.
