Mass balance of Neogene sediments in the Colombia basin relationship with the evolution of the Magdalena and Cauca River basins

“…Several works performed along the CB, in the lower part of the MSF and the lower slope of the SCDB, report the presence of several Mass Transport Complexes (MTC), with variable extensions, from less than 10 km to more than 100 km in length [40], [57], [58]. The 3D seismic data and high-resolution bathymetric information from 2).…”

“…It is common to presume that, in the periods of major relative sea level fall, significant events of MTC become evident, especially in their initial state [95], [120], as a result of the instability of platform and slope areas [121]. However, it has been observed that MTC's can occur at any time during the evolution of the margin [122], and in the SCDB area, the origin of MTC's has been linked mainly to the structural evolution of the anticlines during the Plio-Pleistocene [40], [59], [76]. Considering the high sedimentation rates estimated during the accumulation of sequence S06, added to the major global sea level fall at this time, as well as the important volcanic activity recorded in the Central Cordillera, it may be considered that, the formation of the Cartagena MTC was governed not only by the structural evolution of the margin.…”

Stratigraphic analysis of the Bahia intraslope basin, offshore northern Colombia

“…Several studies have focused on how the evolution Magdalena of related sediments (Figure 7) during the Neogene (Kolla et al, 1984;Duque-Caro, 1991;Hoorn et al, 1995;Ercilla et al, 2002;Estrada et al, 2005;Vinnels et al, 2010;Alfaro and Holz, 2014b;Cadena et al, 2015;Martinez et al, 2015;Ortiz-Karpf et al, 2015;Romero-Otero et al, 2015). The paleo-Magdalena developed initially in the Maracaibo region during the Late Paleogene (Guerrero, 1993).…”

“…The HST episodes, is likely associated to sediment input pulses during Bahia Basin sedimentary-fill. TS3 represent a continuous fine input sediment subsequent, represented (Duarte, et al, 2006;Cadena &Slatt, 2013 andGalindo, 2015). Well tops and unconformities are shown.…”

Regional controls in the distribution and morphometry of deep-water gravitational deposits along a convergent tectonic margin. Southern Caribbean of Colombia

“…Steep anticlines transition rapidly to piggy-back sub-basins, both of which hinder sediment transport from the continental shelf to the basin floor. (Bourget et al, 2011;Cadena et al, 2015;Clark and Cartwright, 2009;Mayall et al, 2010;Morley et al, 2011;Morley and Leong, 2008;Romero-Otero, 2009;Vinnels et al, 2010). Sediment is supplied to the system not only by shelf-edge deltaic Symithe et al (2015) and Martinez et al (2015).…”
