Magnetostratigraphy is a geophysical correlation technique used to date sedimentary and volcanic sequences. The method works by collecting oriented samples at measured intervals throughout the section. The samples are analyzed to determine their characteristic remanent magnetization (ChRM), that is, the polarity of Earth's magnetic field at the time a stratum was deposited. This is possible because volcanic flows acquire a thermoremanent magnetization and sediments acquire a depositional …

Nature of Chronostratigraphic Units. Chronostratigraphic units are bodies of rocks, layered or unlayered, that are defined between specified stratigraphic horizons which represent specified intervals of geologic time.
