ESC2000 Lecture Notes - Lecture 6: Igneous Rock, Oogenesis, Ductility
Document Summary
Large volcanic island systems like japan and indonesia. Deformation change in the shape &/or volume of a body of rock. Results in rock either: folding or fracturing: elastic stress material deforms under stress but returns to its original shape when stress is removed brittly (fractured rock). If the elastic limit is exceeded, the material with deform either ductility (folded rock) or. Factors that affect deformation: type of rock: igneous rock very strong due to interlocking network of mineral crystals brittle. Sedimentary & foliated metamorphic rock typically deform under ductile: high temp ductile. Low temp brittle def: pressure shallow crystal pressure brittle. Deep crystal pressures ductile: time stress over a long time ductile.
