“…The results of this study suggest a northward shift in the source area of the MTCs through time, coinciding with the propagation direction of the structures (e.g. Bernal‐Olaya et al ., ; Martinez et al ., ). This local finding suggests that systematic shifts in MTC source areas through time could be investigated in other areas along the margin to help constrain the evolution of the entire Sinú fold belt.…”

“…According to Martinez et al . (), the structures in the study area have experienced episodic growth since the Late Miocene. This protracted growth history is evidenced by thinning of the stratigraphic packages against the DA and UA, and increased sediment thickness into the syncline (Fig.…”

“…The margin is tectonically active due to Cretaceous‐to‐Recent oblique subduction of the Caribbean Plate beneath the South American Plate (Duque‐Caro, ; Pindell, ; Meschede & Frisch, ; Cediel et al ., ; Pindell & Kennan, ). Plate convergence has resulted in the formation of imbricate thrust folds, which have been active onshore since the Late Palaeocene (Flinch, ) and offshore since the Middle‐Late Miocene (Cediel et al ., ; Martinez et al ., ). The offshore Sinú fold belt is dominated by a series of thrust‐cored anticlines that young to the north (Bernal‐Olaya et al ., ; Martinez et al ., ) and have experienced episodic growth during the Plio‐Pleistocene (Duque‐Caro, , ; Kolla & Buffler, ; Cediel et al ., ; Flinch, ).…”

“…Here, several MTCs were deposited at a time when the Magdalena Fan was prograding under the influence of high sediment supply and the southern Sinú fold belt was propagating outboard to the NW (e.g. Romero‐Otero, ; Martinez et al ., ). Due to the location of the study area within the fold‐and‐thrust belt and to the relatively recent tectonic deformation of the near‐seabed sediments, the degree of deformation is less advanced than in other areas along the fold‐and‐thrust belt (Romero‐Otero et al ., ; Vinnels et al ., ; Alfaro & Holz, ); the primary tectonostratigraphic relationships and internal characteristics of the deposits are, therefore, well‐preserved.…”

Mass wasting is an important process in the degradation of deep‐water fold‐and‐thrust belts. However, the relationship between mass‐transport complex (MTC) emplacement and the timing and spatial progression of contractional deformation of the seabed have not been extensively studied. This study uses high‐quality, 3D seismic reflection data from the southern Magdalena Fan, offshore Colombia to investigate how the growth of a deep‐water fold‐and‐thrust belt (the southern Sinú fold belt) is recorded in the source, distribution and size of MTCs. More than nine distinct, but coalesced MTCs overlie a major composite basal erosion surface. This surface formed by multiple syn‐ and post‐tectonic mass‐wasting events and is thus highly diachronous, thereby recording a protracted period of tectonism, seascape degradation and associated sedimentation. The size and source location of these MTCs changed through time: the oldest ‘detached’ MTCs are relatively small (over 9–100 km2 in area) and sourced from the flanks of growing anticlines, whereas the younger ‘shelf‐attached’ MTCs are considerably larger (more than 200–300 km2), are sourced from the shelf, and post‐date the main phase of active folding and thrusting. Changes in the source, distribution and size of MTCs are tied to the sequential nucleation, amplification and along‐strike propagation of individual structures, showing that MTCs can be used to constrain the timing and style of contractional deformation, and seascape evolution in time and space.

Identification of submarine landslides in the Colombian Caribbean Margin (Southern Sinú Fold Belt) using seismic investigations

et al. 2021

Submarine landslides can be triggered by several processes and involve a variety of mechanisms. These phenomena are important sediment transport processes, but they also constitute a significant geohazard. Mapping of the southwestern Caribbean Sea using 3D seismic data has allowed identification of several submarine landslides in the Colombian Margin in the area dominated by the Southern Sinú Fold Belt (SSFB). A poststack depth-migrated seismic cube survey with a 12.5 by 12.5 m bin spacing was used to identify landslides in an area covering 5746 km2. Landslides were interpreted using a seafloor morphologic parameter identification process and the internal deformation of the slope-forming material, as seen from seismic data. A total of 93 landslides were identified and classified based on their movement styles as follows: 52 rotational, 29 translational, and 12 complex landslides. In addition, 12 distinct deformational zones and a zone of mass transport complex (MTC) were identified. Five different ground condition terrains were interpreted based on landslide type and distribution as well as in geologic structures and seismic reflection analysis. Two main processes seem to influence landslides in the study area. First is the folding and faulting involved in the SSFB evolution. This process results in oversteepened slopes that start as deformational zones and then fail as translational or rotational slides. Those individual landslides progressively become complex landslide zones that follow geologic structural orientation. Second is the continental shelf break erosion by debris flows, which fills in intraslope subbasins and continental rise with several MTCs. According to the results, risk of damage by landslides increases in distances shorter than 4 km along structural ridge foothills in the study zone.
