What features would easily distinguish schist and gneiss from quartzite and marble?
Schist and gneiss have a banded texture, whereas quartzite and marble have a more uniform appearance. Schist typically contains platy minerals like mica, while gneiss has alternating layers of different mineral compositions. Quartzite is composed mainly of quartz grains, while marble is comprised of recrystallized calcite or dolomite minerals.
How does gneiss differ from the rock it was formed?
Gneiss differs from the rock it was formed from by having distinct layering or banding of minerals, a higher degree of metamorphism, and a more pronounced foliation. The original rock's mineral composition and texture have been fundamentally changed during the process of gneiss formation.
What rock or rocks could come just after quartzite in the rock cycle?
Schist and gneiss are common rocks that can form after quartzite in the rock cycle. Schist forms from the metamorphism of rocks like shale or mudstone, while gneiss forms from the high-grade metamorphism of granite or other rocks.
Is gneiss ductile or brittle?
Gneiss is a metamorphic rock that typically displays ductile behavior due to its layered composition and high temperature and pressure conditions during formation. This means that it is more likely to be deformed without breaking easily compared to brittle rocks like quartzite.
What is the protolith of a quartzite?
The protolith of a quartzite is a sedimentary rock called sandstone. Quartzite forms when sandstone undergoes metamorphism, typically due to high heat and pressure, causing the quartz grains in the sandstone to recrystallize and merge together.

How could you easily distinguish a black and white gneiss from a similar-colored granite?
gneiss is foliated(layered) so therefore, if you see a black and white gneiss and a similar-colored granite then just see if the gneiss looks like it is layered!
10 examples of metamorphic rocks?

What types of rocks are marble gneiss and quartzite?
they're all metamorphic
How could you easily distinguish a black and white gnesis from a similar colored granite?
Gneiss has a definite foliation of fabric, granite does not.
What is metamorphic rocks's names?
quartzite, slate, gneiss, marlbe, migmitite, amphibolite, serpenrinite, eclogite. that's all i have from my school papers. quartzite, slate, gneiss, marlbe, migmitite, amphibolite, serpenrinite, eclogite. that's all i have from my school papers.

Sandstone can metamorphose into quartzite.
