A – Profile ROK-I; B – Stratified sands in the ROK-I profile; C – Profile ROK-II; D – Fining-upward succession of the point bar with erosional channel in the central part; E – Lower part of the point-bar succession with tree trunks (yellow arrow) in the lower part of the point bar; F – Transition of upper part of the point bar (sands with ripple cross-lamination) into fine sediments of the floodplain; G – SSDs in the upper part of the point bar. SSDs, soft-sediment deformations.
