Principal component analysis (PCA) of first-order reversal curve (FORC) diagrams for core KR13-02 PC06. a Distribution of 26 FORC data (squares) on the principal component PC1-PC2 plane. Triangular dashed lines define a three-endmember (EM) system, and the arrow indicates the general downcore trend. b FORC diagrams for EM1, EM2, and EM3
