Downcore variations of FORC-PCA endmembers (EMs) and kARM/SIRM for core KR13-02 PC06. a The proportion of EM1 (red), EM2 (blue), and EM3 (green). b SIRM (black) and the contribution to SIRM of individual EMs calculated from the respective proportions. c Variations of kARM/SIRM. Note the synchronous changes of EMs and kARM/SIRM at ~ 2.7 m, and an EM3 increase between ~ 6.7 and 8.2 m
