Comparisons of combinations of one hysteresis (Bc or Bcr) and the other Ms-T curve (ITC|m|) parameters between the TS API “success” and “failure” data subsets. (a and b) Biplots of Bcr vs. ITC|m| and Bc vs. ITC|m|, respectively, with the consideration of when a minimal set comprising two different rock-magnetic parameters is adopted as the “sample priority selection criteria;” the proposed threshold values (Bcr ≥ 26 mT and ITC|m|≤ 0.15, and Bc ≥ 13 mT, and ITC|m|≤ 0.15, respectively; “Exploring ‘ease-of-use’ rock-magnetic parameters for the sample preselection criteria” section) of the two variables in each biplot are indicated by black solid lines; the pale yellow shaded zone of each biplot represents the zone distributed by data meeting the respective minimal set of criteria
