What else can I help you with?
Is quartz felsic?
Yes, quartz is felsic. Felsic minerals are rich in silica (SiO2) and aluminum (Al2O3), which are primary components of quartz. Quartz is commonly found in felsic igneous rocks such as granite and rhyolite.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
What elements do falsic rock contain?
Felsic rocks are primarily composed of light-colored minerals rich in silica and aluminum. Key elements found in felsic rocks include silicon (Si), oxygen (O), aluminum (Al), sodium (Na), and potassium (K). Common minerals in felsic rocks include quartz and feldspar, which contribute to their overall composition and characteristics. These rocks are typically less dense and more viscous than mafic rocks.
Are there other elements found in stars than hydrogen and helium?
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
What elements are present in trace amounts only?
Elements that are present in trace amounts include substances like uranium, thorium, and other radioactive elements that are found in very small concentrations in the Earth's crust. These elements are not as commonly encountered as elements like oxygen, carbon, and silicon.
Is thorium found in UK?
United Kingdom hasn't today known reserves of thorium.
Is quartz felsic?
Yes, quartz is felsic. Felsic minerals are rich in silica (SiO2) and aluminum (Al2O3), which are primary components of quartz. Quartz is commonly found in felsic igneous rocks such as granite and rhyolite.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
Why are they called rare earth elements?
Rare earth elements are called so because they are not commonly found in high concentrations in the Earth's crust, making them relatively scarce compared to other elements.
Which pair of minerals is most likely to be found in felsic rock?
Quartz and feldspar are the most likely pair of minerals found in felsic rock. Felsic rocks are rich in silica, which forms minerals like quartz, and feldspar is another common mineral found in these rocks.
What does the word felsic mean?
Felsic refers to rock rich in silica and aluminum content. It describes igneous rocks that are light in color and have high concentrations of minerals like quartz and feldspar. Felsic rocks are commonly found in continental crust.
What is the difference in density in mafic rocks in relation to felsic rocks?
Mafic rocks, such as those found in the oceanic crust, are more dense than the felsic rocks found in the continental crust.
Which minerals is rarely found in felsic igneous rocks?
they are found in approximetily 90 %in the earth crust
Are there other elements found in stars than hydrogen and helium?
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
What elements are present in trace amounts only?
Elements that are present in trace amounts include substances like uranium, thorium, and other radioactive elements that are found in very small concentrations in the Earth's crust. These elements are not as commonly encountered as elements like oxygen, carbon, and silicon.
What are the trace elements commonly present in stable minerals?
Some common trace elements found in stable minerals include titanium, manganese, strontium, and chromium. These elements are usually present in very low concentrations compared to the major elements in the mineral structure.
Were are pumice rocks found?
In areas of past or present explosive felsic volcanism
