Because it it unstable on the suface of the earth

Olivine weathers quickly when exposed to water and air, transforming into other minerals like clay minerals. This rapid weathering process results in olivine being rare in sandstone found on beaches, even in volcanic islands where olivine is abundant in the rocks.

Why do newly formed volcanic islands have a rich supply of minerals?
Newly formed volcanic islands have a rich supply of minerals because volcanic activity brings minerals from deep within the Earth to the surface. The lava and ash contain various minerals that were once part of the Earth's mantle, which contribute to the fertile soil and mineral deposits found on these islands. Over time, this creates a nutrient-rich environment that supports the growth of vegetation.
Why do new volcanic islands have a rich supply of minerals?
New volcanic islands have a rich supply of minerals because the volcanic activity brings minerals from deep within the Earth's mantle to the surface during eruptions. These minerals, along with the rapid weathering of volcanic rocks, create nutrient-rich soils that support abundant plant and marine life. Over time, these conditions can yield valuable mineral deposits.
Is rhyolite a rock or mineral?
It is a volcanic rock.
What is the hardness of a volcanic rock?
Volcanic rocks can vary in hardness depending on their mineral composition. On the Mohs scale of mineral hardness, most volcanic rocks fall between 5 to 7, with basalt being around 6 and rhyolite around 7.
What is the mineral resource of montserrat?
Montserratt's mineral resources include volcanic rock deposits such as pumice and ash, as well as geothermal energy sources due to its volcanic activity. However, due to its small size and limited exploration, the mineral potential of Montserrat is not extensively documented.
Is volcanic glass a mineral?
Volcanic glass is not a mineral. It's composition is complex, and their is no crystalline structure.

Which biome includes volcanoes?
Volcanoes can be found in various biomes, but they are most commonly associated with the volcanic biome. This biome is characterized by the presence of active and dormant volcanoes, mineral-rich soils, and unique plant and animal species adapted to volcanic activity. Volcanic biomes are often found near tectonic plate boundaries and have distinct landscapes shaped by volcanic eruptions.
Volcanic particles about the size of a rice grains are called?
Volcanic particles about the size of rice grains are called volcanic ash. Ash is made up of small rock and mineral fragments that are expelled during a volcanic eruption.
How is volcanic glass different from a mineral?
Volcanic glass is not a mineral but rather a type of amorphous solid formed when molten lava cools rapidly. It lacks a crystal structure and specific chemical composition that define minerals. Minerals are crystalline substances with a specific chemical composition and atomic arrangement.
Is sulfuric a mineral?
no
What type of rocks is the quartz?
Quartz is a mineral that is formed by volcanic action. It is the second most common mineral. Feldspar is more common.
