Isothermal Remanent Magnetization (IRM) acquisition curves for the unclassified IRD > 1mm fractions of sediment core GeoB18530-1

IRM acquisition curves (and their derivatives) resolve the cumulative coercivity distribution (and spectrum) of a magnetic mineral assemblage. Here we present IRM data for all extracted unclassified IRD > 1mm fractions. The IRM acquisition curves were acquired in logarithmically increasing pulse field steps from 10 mT to 2600 mT and measured by DC SQUIDS inside the 2G rock magnetometer without exposure to the external geomagnetic field. The varying magnetic peak field values shown here are based on real time peak field measurements by an integrated induction coil. Although samples were previously AF demagnetized, but some samples have hard initial remanent magnetizations, that could not be entirely removed.
