Schist and gneiss are metamorphic rocks that display foliation, the parallel layering of the minerals caused by immense pressures. Quartzite and marble do not display foliation as they are metamorphosed more by heat than by pressure.
The presence of visible minerals aligned in bands or layers would distinguish schist and gneiss from quartzite and marble. Schist and gneiss show foliation due to intense metamorphism, while quartzite and marble are more homogenous in texture.
They are both metamorphic rocks. One difference is the rocks they are formed from. Gneiss is formed from Feldspar and Quartz. Gneiss can also contain muscovite, biotite and hornblende. Quartzite is formed from sandstone. Also Gneiss is more intensely foliated than Quartzite. This can be seen in the bands formed in Gneiss, while quartzite has no bands. Pure quartzite is white, while Gneiss is grey or pink, with dark streaks.
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.
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.
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.

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!
they're all metamorphic
- Amphibolite - Eclogite - Gneiss - Greenstone - Hornfels - Marble - Migmatite - Phyllite - Quartzite (Metaquartzite) - Schist - Slate - Soapstone

Gneiss has a definite foliation of fabric, granite does not.
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.
Pennsylvania is home to quartzite, slate, marble, phyllite, gneiss, and schist
marble used to be limestone

Yes, and it looks very gneiss.
Sandstone can metamorphose into quartzite.
