Identify three minerals that are normally found with quartz in samples of andesite rock?
Three minerals commonly found with quartz in andesite rock are feldspar (specifically plagioclase), biotite mica, and amphibole (such as hornblende). These minerals are all typically present in andesite as part of the overall composition of the rock.
Which minerals can be found in all samples of rhyolite and andesite?
Both rhyolite and andesite typically contain the minerals quartz, feldspar (particularly plagioclase and alkali feldspar), and biotite. They may also contain other minerals such as hornblende or pyroxene, though these are more variable. The presence of these minerals contributes to their characteristic compositions and textures. Rhyolite is generally more silica-rich than andesite, resulting in differences in mineral proportions.
Where does andesite form?
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
Which minerals are found in andesite?
Andesite is primarily composed of plagioclase feldspar, along with significant amounts of pyroxene and amphibole. It may also contain smaller quantities of biotite and quartz, depending on its specific composition and the conditions under which it formed. This volcanic rock typically exhibits a fine-grained texture, reflecting its rapid cooling from molten lava. The mineralogy of andesite can vary based on its volcanic source and the surrounding geological context.
Does Andesite contain CaCO3?
No. Calcium carbonate is found in sedimentary and metamorphic rocks. Igneous rocks such as andesite are composed almost entirely of silicates.
What are some minerals that have quartz in them?
Quartz is a mineral. No other minerals contain quartz.
What is the difference in composition between a dacite and an andesite?
The main difference between dacite and andesite lies in their silica content. Dacite has a higher silica content than andesite, making it more viscous. Dacite also typically contains more quartz and less mafic minerals than andesite.
What items contain quartz?
Quartz hasn't uses at home.
What is the mineral composition of andesite?
basalt and dacite, and ranges from 57 to 63% silicon dioxide (SiO2)
Are andesite grains small?
Andesite typically has a groundmass ~ 50% of grains <.25mm of metallic oxides and quartz interspersed with larger phenocrysts of pyroxene and plagioclase feldspar. Other accesory minerals may be present.
Does marble contain quartz?
Yes, marble does contain quartz. Quartz is one of the minerals that can be present in marble, along with other minerals like calcite and dolomite. The amount of quartz in marble can vary, but it contributes to the overall composition and appearance of the stone.
Does quartz have carbon?
No. Quartz contains SiO2, so there is no carbon.
