Fig. 6: A comparison of detrital zircon U-Pb ages from the northeastern and central-western CLP.

Black and blue lines are normalized probability density function (PDP) and kernel density estimation plots (KDE), respectively, and open rectangles are age histograms. From left to right, the blue, purple, green and orange shadows indicate the ages in the range of 200–300 Ma, 400–500 Ma, 800–1000 Ma, and 1500–2750 Ma, respectively. JX-Jiaxian from the northeastern CLP; CN-Chaona from the central-western CLP.
