Unformatted text preview: hickening of the growth strata to the east, the location of the hanging wall cutoff east of the axis of the Gualanday syncline, and preservation of the eastern, but not of the western growth axial traces, indicate that the Cambao thrust sheet was moving westward to southwestward when growth strata accumulated. Paleogeographic interpretation Stratigraphic criteria summarized above was interpreted to indicate that the northernmost, northeast-trending segments of the Camaito and Cotomal faults, and the El Guaco anticline started growing during early to late Campanian times (Fig. 2a). These gentle structures were later overlapped by the Maastrichtian conglomerate of the La Tabla Formation, that records unroofing to the west (Cordillera Central). The early Paleogene (Fig. 2b) marks a time of segmentation of accumulation environments due to the west- or southwestward propagation of the Cambao fault (and probably other faults in this foldbelt), and generation of accommodation space in the Guaduas and Gualanday synclines.
