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.
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. T...
