First-order reversal curve (FORC) diagrams provide information about domain states and magnetostatic interactions that underpin paleomagnetic interpretations. FORC diagrams are a complex representation of remanent, induced, and transient magnetizations that can be assessed individually using additional FORC-type measurements along with conventional measurements. We provide the first extensive assessment of the information provided by remanent, transient, and induced FORC diagrams for a diverse range of soil, loess/paleosol, and marine sediment samples. These new diagrams provide substantial information in addition to that provided by conventional FORC diagrams that aids comprehensive domain state diagnosis for mixed magnetic particle assemblages. In particular, we demonstrate from transient FORC diagrams that particles occur routinely in the magnetic vortex state. Likewise, remanent FORC diagrams provide information about the remanence-bearing magnetic particles that are of greatest interest in paleomagnetic studies.
