Pyroxenes have a single chain structure, while amphiboles have a double chain structure. Pyroxenes typically have a simpler, more elongated crystal structure compared to the more complex, ribbony structure of amphiboles. Additionally, pyroxenes commonly have a monoclinic or orthorhombic crystal system, while amphiboles have a monoclinic system.

Astenosphere contain pyroxenes and olivines.

Pyroxenes have a single-chain structure composed of silica tetrahedral chains linked to metal cations, typically magnesium and iron, in octahedral coordination. This structure gives pyroxenes their characteristic two-directional cleavage.

pyroxenes

yes it is made up of olivine and various pyroxenes

Mostly the Moon's solid mantle comprises olivene and pyroxenes.

Amphiboles have a more complex structure than pyroxenes because they contain additional layers of oxygen and hydroxyl groups. This leads to a greater variety of chemical compositions and structural arrangements within amphiboles compared to pyroxenes. Additionally, amphiboles often exhibit more pronounced cleavage planes and a wider range of physical properties due to their more intricate structure.

Quartz and the Feldspar are very common.

Other common silicates would be the mica group, even pyroxenes and the amphiboles.

Examples of ferromagnesian silicate minerals include olivine, pyroxenes (such as augite), amphiboles (such as hornblende), and biotite mica. These minerals contain iron and magnesium in their crystal structures, which contribute to their dark color and magnetic properties.

The upper mantle consists mainly of ultramafic rocks such as peridotite, which is rich in olivine, pyroxenes, and feldspar. These rocks are dense and typically dark in color due to their composition.

The density of pyroxenite varies depending on its composition, but it typically ranges from 3.0 to 3.5 g/cm3.

There are many sorts of igneous rocks. Granite is made of quarts, feldspar, and mica, while basalts are made of less than 20% quartz and less than 10% feldspar and the rest made up of pyroxenes and olivine.

Quartz, feldspar, mica, amphibole, and pyroxene are five common rock-forming minerals found in many types of rocks.

Dunite is primarily composed of olivine, which is a magnesium-iron silicate mineral. It may also contain small amounts of chromite, pyroxenes, and other minerals associated with ultramafic rocks.

most likely Mg rich pyroxenen since Fe starts melting earlier from a melt and also mantle rocks that are highly melt depleted contain very high mg rich pyroxenes

The igneous rock with mostly pyroxenes and olivine is likely a mafic rock, such as basalt or gabbro. These minerals are common in mafic rocks due to their high iron and magnesium content. Mafic rocks are associated with oceanic crust and volcanic activity.

The upper mantle is typically a greenish-brown color due to the presence of minerals like olivine and pyroxenes. However, the upper mantle is located below the Earth's crust and is not directly visible, so its color is based on scientific observations and studies rather than direct observation.

The upper mantle is very close in chemical and mineralogical composition to the lower mantle, as both layers are primarily composed of silicate minerals such as olivine, pyroxenes, and garnet. These minerals make up the majority of the Earth's mantle and are responsible for its solid but flowing behavior.

The lunar surface is primarily made of igneous rocks, such as basalt and anorthosite. It also contains regolith, which is a layer of loose rock, dust, and soil created by the impact of meteorites and micrometeorites. Additionally, there are deposits of minerals like ilmenite and pyroxenes.

Moon rocks are primarily composed of basalt, a volcanic rock rich in iron and magnesium. They also contain minerals such as plagioclase feldspar, pyroxenes, and olivine. Additionally, moon rocks may contain glass beads formed from melted rock during meteorite impacts on the surface.

Soapstone is a metamorphic rock composed primarily of talc with varying amounts of chlorite, pyroxenes, micas, carbonates, and amphiboles. It is known for its softness, smooth texture, and high heat resistance, making it popular for use in countertops, sinks, and carvings.

The six main types of crystalline structures in silicate materials are framework silicates (e.g., quartz), sheet silicates (e.g., muscovite), chain silicates (e.g., pyroxenes), single tetrahedra (e.g., olivine), double tetrahedra (e.g., garnet), and ring silicates (e.g., beryl).

Yes, olivine is a key mineral in peridotites and other ultramafic rocks, typically making up a substantial portion of their composition. It is a primary mineral in these rocks, alongside other minerals like pyroxenes and chromite. Olivine's presence helps characterize these rocks and plays a role in their formation and geologic processes.

The middle mantle is composed mainly of silicate minerals such as olivine, pyroxenes, and garnet. These minerals are dense and can withstand high pressure and temperature conditions found at this depth within the Earth. The middle mantle makes up a significant portion of the Earth's interior and plays a crucial role in the planet's internal dynamics.

When two single chains of tetrahedra bond to each other, the resulting structure is called a double chain silicate. These structures typically involve each tetrahedron sharing three oxygen atoms with adjacent tetrahedra, forming a linked double chain. Examples include amphiboles and pyroxenes.

About 200 minerals make up the bulk of most rocks. The feldspar mineral family is the most abundant. Quartz, calcite, and clay minerals are also common. Some minerals are more common in igneous rock (formed under extreme heat and pressure), such as olivine, feldspars, pyroxenes, and micas.

Phobos is primarily composed of carbon-rich rock and regolith (loose, fragmented material). It also contains minerals such as pyroxenes and olivines. In addition, traces of water ice and organic molecules have been detected on its surface.

Basaltic lava is far less viscous, has less silica, erupts at a higher temperature and is denser than granitic lava (properly called rhyolitic lava when it is on the surface). Basaltic lava is composed primarily of pyroxenes and calcium rich plagioclase with small amounts of olivine. Rhyolitic lava primarily contains alkali feldspars and quartz.

The chemical formula for soapstone is primarily composed of talc, with a composition of (Mg,Fe)3Si4O10(OH)2. It also contains varying amounts of other minerals such as chlorite, pyroxenes, micas, and carbonates.

Mafic minerals are rich in magnesium and iron, like pyroxenes and olivine. Felsic minerals are rich in silica, potassium, and sodium, like quartz and feldspar. These minerals are used to classify rocks based on their mineral composition.

Talc is formed from the metamorphism of magnesium-rich minerals such as serpentine, pyroxenes, and amphiboles. The heat and pressure from geological processes cause these minerals to undergo chemical changes, transforming them into talc. Over time, the talc can accumulate into deposits that are mined for various industrial applications.

The Earth's mantle is primarily composed of a rock called peridotite. Peridotite is rich in iron and magnesium minerals such as olivine and pyroxenes. It represents the majority of the Earth's volume and is a key component of the mantle's composition.

Iron-rich pyroxene generally has a higher melting temperature than magnesium-rich pyroxene due to the presence of iron ions, which increases the bonding strength between the pyroxene mineral components, requiring higher temperatures to break these bonds.

The mantle is composed of solid rock, but it mainly consists of silicate minerals rich in iron and magnesium. Some common minerals found in the mantle include olivine, pyroxene, and garnet.

You can only make a rough guess and you would also need to feel it and gauge its density and any visible structures it had or components it was made from.

For instance it the rock is white, soft, light and contains lots of fossil shells it is probably made out of calcium carbonate (a limestone).

If it is light in weight, hard and made of visible grains, it is probably a sandstone and made mostly of quartz.

If the rock is heavy, dark in colour, very solid and with visible crystals it is probably an intrusive igneous rock made up of feldspar, pyroxenes and quartz.

Mars is primarily composed of silicate rocks, minerals like pyroxenes and olivine, and iron oxide dust that gives it its reddish color. The planet also contains water ice in its polar caps and underground, as well as carbon dioxide in its thin atmosphere.
