The luster of gneiss is typically described as shiny, reflective, and sometimes sparkly due to its mineral composition. Gneiss is a type of metamorphic rock formed from the alteration of existing rock under high heat and pressure, resulting in its distinct luster.
gniess is made of granite
Gneiss is generally coarse-grained.
luster
No. Amethyst has a vitreous (glassy) luster.
Yes, nickel has a luster. It is a silvery-white metal with a shiny appearance.
gniess is made of granite
Gniess is Metamorphic.
Gniess is formed from pre-existing rocks that are subjected intense derectional pressure.
Yes
because of the minerals that are mixed in with the gniess during the rock cycle(probably at the igneous stage) reflect light off of themselves
Metamorphic.
Granite turns into Gniess.
gniess, slate, and quartzite
Gneiss is generally coarse-grained.
Yes. Gneiss is a foliated metamorphic rock.
