Statement

Speleothems were imaged on a Leica SP2 confocal microscope using an oil immersion objective lens. Individual images of 1024 x 1024 pixels at 2x zoom were acquired over the entire length of the speleothems by 3 microscope fields in the y axis. The Leica LCS software automatically stitched all the image frames to produce a montage of both samples. Laser excitation wavelengths of 488 nm and 515 nm were used to detect the autofluorescence of the organic matter with emission detection set to 540 – 680 nm; pixel resolution was 0.183 µm. Greyscale line profiles were produced for each photomosaic using the image processing software ImageJ and imported into Matlab. The laminae were measured and counted using the automated peak-counting algorithm of Smith et al. (2009). Age models were produced using a combination of magnetostratigraphy, orbital tuning and U-Th dating (see Hopley et al., 2018).
