schist and gneiss arefoliated and in gneiss you can see the bands.
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.
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.
Metamorphosed sandstone may become quartzite and limestone may become marble.
Quartzite--sandstone. Marble--limestone. Slate--shale. Gneiss--basalt or granite.
Slate is naturally flaky, and easily splits into plates that can be used for roofing. Gneiss doesn't.

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
Gneiss has a definite foliation of fabric, granite does not.
- Amphibolite - Eclogite - Gneiss - Greenstone - Hornfels - Marble - Migmatite - Phyllite - Quartzite (Metaquartzite) - Schist - Slate - Soapstone
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
Metamorphosed sandstone may become quartzite and limestone may become marble.
gneiss, schist, slate
Marble
