The Early Cambrian Mianyang-Changning Intracratonic Sag and Its Control on Petroleum Accumulation in the Sichuan Basin, China

Figure 6

Cross-sections showing Early Paleozoic strata geometries in the intracratonic sag. ((a) spatial distribution of the sag indicated by the isopach map of the Maidiping-Canglangpu Formations; the sag is characterized by asymmetrical, N-S striking geometry. The sag can be subdivided into three segments; in particular, the eastern margin is much steeper than the western margin. (b) E-W striking cross-section of the sag in Leshan-Yibin-Zigong area. (c) N-S striking cross-section of the sag in Mianzhu-Changning area.)
