post-depositional remanent magnetization
post-depositional remanent magnetization . The magnetization acquired by a sedimentary rock after deposition and before undergoing metamorphism, mostly associated with chemical remanent magnetization as ferromagnetic minerals grow during diagenetic alteration (see DIAGENESIS), but it also results from the physical rotation of magnetic grains associated with the movement of fluids and gases through the rock.
