The interlocking mineral grains of gneiss make it resistant to weathering because they prevent water and air from easily penetrating the rock. Gneiss also has a high content of resistant minerals like quartz and feldspar, which are less prone to chemical breakdown. Additionally, the banding in gneiss provides structural integrity that helps resist weathering.
What else can I help you with?
Which property of the gneiss sample prevented it from weathering?
The property of foliation in gneiss, caused by its alternating layers of minerals, makes it resistant to weathering. This foliation gives gneiss a strong and cohesive structure, preventing the rock from easily breaking down in response to weathering processes.
Is gneiss soft or hard?
Gneiss is hard.
Does gneiss have fracture?
Yes, gneiss can exhibit fractures due to tectonic stresses or weathering processes. The type and extent of fractures in gneiss can vary depending on factors such as mineral composition, pressure, and temperature conditions during formation.
How gneiss could turn into sand and clay?
Gneiss can weather and erode over time due to exposure to physical and chemical processes like temperature changes, water, and chemical reactions. These processes break down the minerals within the gneiss into smaller particles, which eventually form sand and clay. Gradual weathering and erosion transform the gneiss into these smaller sediment particles through the processes of physical breakdown and chemical alteration.
What are some features of the gneiss rock?
The foliations of gneiss make beautiful swirls and patterns in polished countertops and building slabs. Many so-called granite countertops are actually gneiss. Gneiss makes a gneiss [sic] countertop! If by useful you mean info on gneiss, it is basically a coarse-grained, foliated, high grade metamorphic rock. Gneiss forms during high grade, regional metamorphism, and can form from amny different parent rocks including shale and igneous rocks. Most gniesses are often granitic in composition and one variety forms from the metaporphism of granite. Gneisses are also named for the dominant material such as biotite gneiss or garnet gniess. - David Miller

What property distinguishes foliated metamorphic rock such as gneiss and schist from nonfoliated metamorphic rocks?
A banded texture

a banded texture
What group is gneiss in?
A Gneiss is a Metamorphic rock
Is gneiss folaited or nonfolaited?
Gneiss is foliated.
What is the rock type for kaolinite?
Kaolinite is a clay mineral belonging to the group of silicates. It is formed mainly from the weathering of rocks rich in feldspar, such as granite and gneiss. It is commonly found in sedimentary rocks and soils.
Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
