What else can I help you with?
Why would you would you not find quartz or olivine in the same igneous rock?
Quartz and olivine have different crystallization temperatures, with olivine forming at higher temperatures than quartz. This means that in most cases, olivine and quartz are not typically found together in the same igneous rock as they would have crystallized at different stages in the cooling process. Olivine is a common mineral in mafic rocks (rich in magnesium and iron) while quartz is more common in felsic rocks (rich in silica).
Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
What are the 2 most common silicate minerals in Earth's crust?
feldspars. feldspars.
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
Which mineral would not have a metallic luster?
A non-metallic mineral such as quartz or calcite.
Why would you would you not find quartz or olivine in the same igneous rock?
Quartz and olivine have different crystallization temperatures, with olivine forming at higher temperatures than quartz. This means that in most cases, olivine and quartz are not typically found together in the same igneous rock as they would have crystallized at different stages in the cooling process. Olivine is a common mineral in mafic rocks (rich in magnesium and iron) while quartz is more common in felsic rocks (rich in silica).
Which silicate minerals are the main component of most of Earth?
They would include olivine, quartz, the feldspars, and the micas.
Why you would not expect to observe an igneous rock with quartz and olivine in it?
Igneous rocks typically form from the crystallization of magma, which has specific chemical compositions. Quartz, a silica-rich mineral, is usually found in felsic rocks, while olivine is a magnesium-iron silicate typically found in mafic rocks. The presence of both minerals in the same rock would indicate a divergent composition, as quartz forms at lower temperatures and olivine at higher temperatures. Consequently, the coexistence of these minerals suggests an unlikely cooling history, making such a rock rare or non-existent in nature.
Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
A sedimentray rock composed of what would weather at a faster rate?
Chalk would weather fastest, followed by limestone.
What are the 2 most common silicate minerals in Earth's crust?
feldspars. feldspars.
What is a common mineral starting with qua?
This would be quartz.
Would rocks on the moon weather faster or slower than on earth?
They would weather slower than on earth due to different amts of wind and rain than on earth.
Would You find fossils in quartz?
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
Which would not be consider as a mineral water diamond mica or quartz?
Quartz
How would you describe the composition of igneous rock?
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.
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
