“…Poag (2017) coined the term "shaken and stirred" for this unit. In fact, Worzel et al (1973) already noted that the Lower Paleocene chalks drilled at Site 95 in a water depth of 1663 m are fractured with many of the fractures annealed.…”

“…GT: Gulf Trough; SS: Suwannee Strait has been drilled in the course of DSDP Leg 10 back in 1970 (Fig. 2; Worzel et al 1973). The results derived from spot coring indicated that the Bank grew as a massive carbonate platform since Cretaceous times.…”

“…With the exception of Cretaceous dolomite, the recovered sediments were of deep-water origin (bathyal depths), indicating that the bank has been in the same relative environment since at least Paleocene or Late Cretaceous. In the context of DSDP Leg 10, Worzel et al (1973) interpreted the steep upper slope of the northern Campeche Bank as the result of upbuilding carbonate sediments. The authors ruled out to see the escarpment as a fault scarp or as the detrital accumulation seaward of a barrier or reef complex.…”

“…The Lower Paleocene chalks drilled on close to our study area at Site 95 in a water depth of 1663 m are fractured. Discontinuities in the section and unconformities observed in the seismic data were interpreted to result from slumping that occurred throughout the Cenozoic along the ECB slope (Worzel et al 1973). As it is typical for a ramp, shallow water sedimentary facies are arranged into depth dependent belts with red and green algae, molluscs, gastropods and foraminifers down to 80 m, and finer grained deposits in deeper waters (Logan et al 1969).…”

“…To constrain the stratigraphic interpretation of lower units ECB1-3, two steps were taken. First, we scaled the GT2-16 profile and a section of DSDP Site 95 pre-site data (Worzel et al 1973) the same and plotted them against each other (Fig. 11).…”

Reading the sediment archive of the Eastern Campeche Bank (southern Gulf of Mexico): from the aftermath of the Chicxulub impact to Loop Current variability

This is the first high-resolution seismic study showing how the Chicxulub impact shaped the eastern slope of the Campeche Bank in the south-eastern Gulf of Mexico. The induced shock wave fractured Cretaceous strata causing the collapse of the upper slope and shelf over a length of ca. 200 km. Failed material was either transported downslope or remained in parts on the accommodation space created by the collapsed. In the Cenozoic, the East Campeche Plastered Drift developed within the created accommodation space, controlled by the inflowing surface current from the Caribbean, which forms the Loop Current. The internal reflection configuration of the drift shows that the closure of the Suwannee Strait in the Late Oligocene and the closure of the CAS in the Mid to Late Miocene controlled the variability of the southern Loop Current in time. Since the Loop Current transports heat and moisture from the western Atlantic warm water pool into the North Atlantic and further to NW Europe by the Gulf Stream, the drift represents an archive for controlling factors that influenced climate of the northern hemisphere. This first high-resolution seismic reflection study from the eastern Campeche Bank expands the understanding of destructive processes that a meteorite impact induces into the earth system. Furthermore, these data document that the East Campeche Plastered Drift bears the potential to understand the link between the climate variability of the northern hemisphere and oceanic processes in the equatorial western Atlantic.
