Fig. 7. Temporal and spatial distribution of the Yingxi E32 subsalt lithofacies. (a) Section of lithofacies with complete sequence in a single cycle for different geomorphic units, with the section line shown in (c); (b) Plane distribution of lithofacies during the shallow-semi-deep lacustrine deposition (S1 in (a)) in the early stage of single cycle lake level decline; (c) Plane distribution of lithofacies during the strand-shallow lacustrine deposition (S2 in (a)) in the late stage of single cycle lake level decline.
