IGNEOUS ROCK - One of the three basic types of rock; formed by the solidification of magma.
ILMENITE- Ti-Fe oxide, TiFeO3, found in achondrites, lunar mare basalts, and shergottites.
Igneous rock is one of the three main Rock types . Igneous rock is formed by magma being cooled and becoming solid . They may form with or without crystallization, either below the surface as Intrusion rocks or on the surface as extrusive rocks...

Igneous rock
a rock that was once molten.
Impact
a collision between two planetary bodies. In the case when one is much smaller than the other (like a meteoroid colliding with the Earth), a crater may be produced on the larger body.
IGNEOUS ROCK
When molten rock cools, igneous rock is formed.
IMPACT BASIN
A impact basin is an impact crater that has a rim diameter greater than 185 miles (300 km). There are over 40 impact basins on the Moon, including Schrodinger (above).
igneous rock -- Rock solidified from a molten state.
Imbrium -- Mare Imbrium - Latin for "Sea of Rains".
Inverness -- In William Shakespeare's Macbeth, the location in Scotland of Macbeth's castle.
The igneous rock in the 4.2-pound, potato-sized meteorite has been age-dated to about 4.5 billion years, the period when the planet Mars formed.
Dark, igneous rock characteristic of solidified lava.
Belts
Dark bands of clouds that circle Jupiter parallel to its equator; generally red, brown, or blue-green; believed to be regions of descending gas.
Norite: Igneous rock found in the lunar highlands composed of plagioclase and pyroxene.
Nucleosynthesis: Element formation by reactions inside stars.
igneous rocks (NASA Thesaurus) Rocks or minerals that solidify from molten or partly molten material, i.e., from magma. The term is also applied to processes leading to, related to, or resulting from the formation of such rocks.
As an example of how this property of igneous rocks allows us to determine that the Earth's field has reversed in the past, consider measurements of magnetism across ocean ridges.
1A class of Magnesium Iron Silicates (Mg, Fe)2SiO4, common components of igneous rocks.

The continental plates consist of lower density material such as the igneous rocks granite and andesite. Less common is basalt, a denser volcanic rock that is the primary constituent of the ocean floors.
igneous rock formed from magma. In the highlands the majority of the rocks are breccias—conglomerates formed from basaltic rock and often studded with small, green, glassy spheres.
One of the wells had bored into a thick layer of igneous rock known as "andesite" about 1.3 kilometers down.
Magma is molten rock (lava) from which igneous rock forms.
MAGNETAR
A magnetar is a highly magnetic star. Magnetar have magnetic fields of about 1015 Gauss, about a thousand trillion times stronger than the Earth's.

Basalt is a type of igneous rock.
BAYER, JOHANNES
Johannes Bayer (1564-1617) was a Bavarian (German) astronomer who first named stars by assigning them to constellations and giving them Greek letters (alpha, beta, gamma, delta, etc.), ...
A coarse-grained igneous rock made largely of plagioclase feldspar (95%), with small amounts of pyroxene (4%), olivine, and iron oxides. Anorthosite makes up about 60% of Earth's crust.
The composition of Asteroid Belt inhabitants varies from primitive ice-rock mixtures to igneous rocks that resemble the crusts of planets, and metal-rich objects that formed from the cores of broken up proto-planets.
The Highlands rocks are largely Anorthosite, which is a kind of igneous rock that forms when lava cools more slowly than in the case of basalts.
At the Venera 8 site, there were indications that the rock composition may be similar in some respects to that of granite or other igneous rocks that compose the Earth's continents.
About 8% of the meteorites that fall on Earth are achondrites, some of which appear to be similar to terrestrial mafic igneous rocks. Most achondrites are also ancient rocks, and are thought to represent crustal material of asteroids.

37. Basalt
Dark, igneous rock characteristic of solidified lava.
Volcanic craters usually crown conical volcanoes and form the opening of the volcanic vent, where lava pools when magma is rising to the surface. The craters of extinct and dormant volcanoes contain solidified lava (igneous rock) and sometimes fill ...
a burial place made out of big stones and those stones are often balancing on top of one another to form an arch or a fort-like structure. Here you can see the one large rock balanced on three upright stones. All of the stones are local igneous rocks.
Evidence indicates that the lunar highlands, or continents, may be formed of a less dense plutonic igneous rock called anorthosite, which consists almost entirely of the mineral plagioclase.
Within the sarsen stone circle were also configurations of smaller and lighter bluestones (igneous rock of diabase, rhyolite, and volcanic ash), but most of these bluestones have disappeared.
