How rocks deform
Nettet20. okt. 2024 · Rocks are hard, solid masses of minerals that have been fused together. Although they can appear to be unbreakable, all rocks eventually deform, resulting in smaller fragments that break down even further over time. The rate of rock deformation depends on a number of factors, but all deformation goes through three successive … NettetUnderstanding how rocks deform over time can lead to elimination of conservatisms in regards to tunnelling design, especially, in the case of nuclear waste repositories where the lifetime span of
