Basalts and gabbros are volcanic rocks that are common to the Earth, Moon, Mars, many large asteroids, and probably to Mercury and Venus.
Mare Basalt
This was collected from one of the darker areas on the moon known as . The mare formed billions of years ago. Large impacted the surface of the moon and broke up the .
BASALT

BIG BANG THEORY
A theory which states that the Universe began to expand after a super powerful explosion of concentrated matter and energy.

Basalts, which are just like the lava that comes out of volcanoes on the Earth. These are relatively high density and dark in color. They contain iron, manganese, and titanium. Obviously, most of this came from the mare regions.
Flood basalt events: 11 occurrences, all associated with significant extinctions[27][28] But Wignall (2001) concluded that only 5 of the major extinctions coincided with flood basalt eruptions and that the main phase of extinctions started before the ...

Citing oceanic basalt 3He/4He ratios and other evidence, J. Marvin Herndon et al contend that the inner core of the Earth is not iron but much denser atoms.
basalt (Photoglossary of Volcanic Terms - USGS) Basalt is a hard, black volcanic rock with less than 53 weight percent silica (SiO2). Because of basalt's low silica content, it has a low viscosity (resistance to flow).

A slab of black basalt stone found in 1799 that bears an inscription in hieroglyphics, demotic characters, and Greek, celebrated for having given the first clue to the decipherment of Egyptian hieroglyphics; from this, ...
"The layers have basaltic sand, sulfate-rich sand and areas with the addition of silica-rich materials, possibly sorted by wind and cemented by the action of thin films of water," says Arvidson. "We're still at a stage of multiple working hypotheses.
In some eruptions, basaltic lava pours out quietly from long fissures instead of central vents and floods the surrounding countryside with lava flow upon lava flow, forming broad plateaus.
effusive eruption a relative quiet volcanic eruption which puts out basaltic lava that moves at about the speed one walks; the lava is fluid in nature; the eruptions at the Kilauea volcano on the island of Hawaii are effusive Einstein, ...
The materials formed of these minerals are classified into four main groups: (1) basaltic volcanics, (2) pristine highland samples uncontaminated by impact mixing, ...
Unlike most other basins on the Moon Orientale is relatively unflooded by mare basalts, exposing much of the basin structure to view; the central portion of Mare Orientale is covered by a thin layer of mare basalt probably less than 1 kilometer deep, ...
4 g/cc, which is comparable to that of (volcanic) basaltic lavas on the Earth (however, the bulk density of the Earth is 5.5 g/cc, because of the dense iron/nickel core).
Most achondrites are chemically similar to basalts and are thought to be the product of melting on large asteroids, moons, and planets. Soon after these worlds formed, they were heated from within and partially melted.
The maria consist largely of basalt, i.e., 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.
Shaped like a rugby or American football because of its fast rotation, 2003 EL61 must be as dense as basalt and be made almost entirely of rock or else its very fast spin would have stretched it out even more than it is already.
The composition of the upper mantle is probably quite similar to the iron—magnesium—silicate mixtures known as basalt. You may have seen some dark gray basaltic rocks scattered across Earth's surface, especially near volcanoes.
Venera 14 landed about 950 km southwest of Venera 13 near the eastern flank of Phoebe Regio at 13° 15 min S by 310 E on a basaltic plain.
Cyan blue denotes basalts. Dark green is a mixture of iron oxide and basalts. Reds and yellows are dusty material containing sulfates.

Oceanic plates are made of basalts (cooled volcanic rock made of silicon, oxygen, iron, aluminum, & magnesium) and are about 6 kilometers thick.
These lava flows are made mostly of a rock called basalt. Basalt is what commonly remains of lava flows on Earth, too.
Olympic Mons, a structure showing all the characteristics of a basaltic volcano, reaches an elevation of more than 25 km (15.5 mi) and measures more than 600 km (370 mi) across its base.
Being denser than other materials, the iron then sank to the centre, forming an iron core and forcing the less-dense basaltic lavas onto the surface.
Vesta is a dry body that has been resurfaced by basaltic lava flows, and may have an early magma ocean like Earth's Moon.
Locations of localized basaltic vulcanism generally away from plate boundaries. They account for only of the 's heat flow. The correlate with geoid highs, suggesting that they are due to deep-seated plumes.
Lava, usually of basaltic composition, is ejected relatively quietly and continuously from the fissures and forms enormous plains or plateaus of volcanic rock.
We now know that the maria are made from basalt, formed as molten rock [in a previously hot interior] that welled up and flowed out over the Lunar surface, covering the older, cratered landscape.
They actually turned out to be basaltic flows, hardened lava which long ago flowed out of fissures on the Moon; no present-day volcanism on the Moon has been reliably identified.
The soil tests done by these robot explorers show that the composition of the surface of Venus is mostly basalts, much like the surface of the Moon.
The maria are vast impact basins which have been filled with basaltic rocks some 3000 million years ago. Much of the Moon's surface is covered with craters. These are the result of impacts by meteors.
The opacity of stellar material derived by Kramers, who in 1923 carried out theoretical calculations of stellar opacity as a function of chemical composition. [H76]
KREEP
Lunar basaltic material rich in radioactive elements.
Under various conditions ice can have viscosities and flow properties similar to different types of molten rock (basaltic - rhyolitic), and therefore may also result in the formation of similar geologic structures.
