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.
Where does andesite form?
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
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)
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.
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 quartz have carbon?
No. Quartz contains SiO2, so there is no carbon.
What household items contain quartz?
Household items that may contain quartz include countertops, decorative items, lamps, and crystal glassware. Quartz is a common mineral used in various household products due to its durability and aesthetic appeal.
Do kimberlites contain quartz?
Kimberlite is what geologists call "ultrabasic" rock because it does not contain quartz or feldspar. Those are the two most common rock-forming minerals.
