Lake level fluctuation of studied section. A Thickness variations of single gravel-sand deposits. Thinner gravel-sand deposits indicate shallower water; B Mudstone color variations, a lighter color indicates shallower water; C Major and trace elements content variations, the V/Ni ratio is negatively correlated to the water depth, thus, a higher value indicates shallower water (Jones & Manning, 1994); and D The lake level fluctuation is inferred based on (A, B and C). SQ1–SQ4: relatively deep water; SQ5: medium water depth; SQ6: relatively shallow water
