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.
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.
Gneiss is hard.
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.
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.
I am trying to find out what the other two types of rock besides gneiss form the Matterhorn. Gneiss is a metamorphic rock. That's a nice piece of gneiss!
