From: Cement stratigraphy: image probes of cathodoluminescent facies
Crosscorrelation of the two cement sequences. From up to down cement sequences (M mottled, C concentric, e extinct, O oscillatory, FHI final homogeneous infill); extracted R signal profiles; extracted peaks from the R profiles after smoothing by moving average; crosscorrelogram of A and B sample peaks. On the basis of a Student test, significant lags are overlined in blue and unsignificant lags in green; best fit position of the superposed of A and B sample peaks; features correlation of the cathodoluminescence zonations for the two extracted lines
