“…The Paleogene period in the northern Andes and the onshore Colombian Caribbean basins was characterized by an increase in morphotectonic activity (Van der Hammen, 1961;Restrepo-Moreno, 2009;Villagómez et al, 2011;Spikings et al, 2015;Restrepo-Moreno et al, 2019) that modified regional paleogeography, triggering the production and transport of detrital materials and the generation of synorogenic basins (Ayala et al, 2012;Mora-Bohórquez et al, 2017;. Sedimentary sequences in this region keep a record of uplift, exhumation, erosion, sediment production, and deposition in the northern Andes (Hernández and Jaramillo, 2009;Nie et al, 2012;Bernal-Olaya et al, 2015;Mora et al, 2018;Cardona et al, 2018). Additionally, some of these units have been the focus of research because the high number of oil and gas seeps reveals an active petroleum system (e.g., Barrero et al, 2007).…”

Provenance of Eocene–Oligocene sediments in the San Jacinto Fold Belt: Paleogeographic and geodynamic implications for the northern Andes and the southern Caribbean

et al. 2019

Mesozoic and Cenozoic strata of the San Jacinto Fold Belt (Colombian Caribbean) provide insights about sedimentary environments and paleogeographic evolution in the transition between the northern Andes and the South Caribbean deformed belt. We report new provenance (conventional sandstone petrography, heavy mineral analysis, and detrital zircon U-Pb geochronology and typology) and micropaleontologic data (palynology, calcareous nannofossils, and foraminifera) in samples collected from the lower Eocene (San Cayetano Formation) and upper Eocene–Oligocene (Toluviejo and Ciénaga de Oro Formations) rocks in boreholes drilled by the Colombian Agencia Nacional de Hidrocarburos as well as from recently exposed Oligocene outcrops from the Ciénaga de Oro Formation. Sandstone petrography shows modal variations, with high feldspar content in the lower Eocene rocks and high quartz content in the Oligocene deposits. This shift in compositional maturity may be due to climatic variations, tectonic activity, and/or changes in source areas. Heavy mineral analyses indicate variations that suggest sources primarily related to felsic igneous and/or low-grade metamorphic and mafic and ultramafic rocks. Zircon U-Pb geochronology displays age populations mainly in the Late Cretaceous, Late Jurassic, Permian–Triassic, and Precambrian (ca. 900–1500 Ma). In addition, zircon typology analyses indicate that the igneous zircons came primarily from monzogranites and granodiorites. Finally, the micropaleontologic and sedimentary data sets indicate that the sediments were deposited in tropical coastal and shallow marine environments. The sediments were transported by short rivers from the crystalline massifs of the Lower Magdalena Valley and the northern Central Cordillera basements, while distal transport of sediments may have occurred along longer rivers, which brought sediments from southern regions located between the Central and Western Cordilleras.

“…We use the Caribbean tectonic model of Pindell and Kennan () as a framework; their reconstruction is the current and most widely accepted model for the evolution of the Caribbean Plate and has been tested by kinematic (Bochman et al, ) and tomographic (Van Benthem et al, ) studies. Furthermore, we integrate data from previous paleogeographic reconstructions at both regional (Escalona & Mann, ; Mann et al, ; Pindell et al, ; Pindell & Kennan, ) and local scales (Bayona et al, ; Bernal‐Olaya et al, a; Cardona et al, ; Agustín Cardona et al, ; Duque‐Caro, ; Flinch, ; Gomez, et al, a; Mora et al, ; Moreno‐Sánchez & Pardo‐Trujillo, ; Reyes‐Harker et al, ; Villamil, ).…”

“…During Eocene times, the northward movement of the Caribbean Plate was halted due to the collision against the North American Plate, resulting in an eastward movement of the Caribbean Plate relative to South America, which induced a more orthogonal subduction zone beneath South America (Müller et al, ; Pindell & Kennan, ). This subduction formed a continuous N‐S uplifted region, which includes the Central Cordillera, the Santa Marta Massif, the Guajira Peninsula, and Leeward Antilles, and is also represented by intrusive magmatism along the margin and intra‐plate volcanism (Bayona et al, ; Cardona et al, ; Cardona et al, , ; Zapata et al, ; Figure a). Onshore regions were characterized by subaerial depocenters with fluvial environments, as part of the proto‐Maracaibo Basin (Ayala et al, ; Escalona & Mann, ; Gomez et al, a; Gomez et al, b; Villamil, ).…”

Basin Evolution and Shale Tectonics on an Obliquely Convergent Margin: The Bahia Basin, Offshore Colombian Caribbean

Oblique convergent margins accumulate strike-slip deformation that controls basin formation and evolution. The Bahia Basin is located offshore, proximal to major strike-slip fault systems that affect northern Colombia. It lies behind the toe of the modern accretionary prism, where the Caribbean Plate is being subducted obliquely beneath South America. This is the first attempt using 3-D seismic reflection data to interpret a complex strike-slip basin at the western end of the southern margin of the Caribbean Plate. Detailed 2-D and 3-D seismic mapping of regional unconformities and faults is used to describe the structural geometry, timing, and evolution of extensional and strike-slip faults, which controlled the formation of the basin. Analysis of the fault zones is coupled with a description of the seismic-stratigraphic units observed within the Bahia Basin to reconstruct the spatial and temporal evolution of deformation and to evaluate the influence of the pervasive shale tectonics observed in the area. The results, presented as a series of structural-paleogeographic maps, illustrate an initial stage of transtension that controlled the formation of shale-withdrawal minibasins from late Oligocene to late Miocene times. The continuous deformation and northward expulsion of the Santa Marta Massif resulted in transpression during Pliocene times, leading to basin inversion and ultimate closure of the basin. Basin evolution along the southern Caribbean oblique, convergent margin, shows the occurrence of a complex interaction between subduction and major-onshore strike-slip fault systems and illustrates how strain-partitioning led to the break-up and lateral displacement of early accretionary prisms formed along the margin.

“…Similarly, the Colombian Central Cordillera rose between 22 and 18 million years ago (Mya). On the other hand, there is a common geological origin of the Chocó (western Colombia) and Darién (eastern Panama) regions, as both are part of the Panama microplate, more specifically, the Chucunaque–Atrato geological blocks (Borrero et al , Montes et al , Cardona et al , León et al ). The collision of the Chucunaque – Atrato basin and its associated magmatic arc with South America began during the late Miocene circa 10 Mya, resulting in the collision that fused the Panamanian magmatic arc with the western Andes of Colombia along the Uramita suture (Montes et al , León et al ).…”

The genus Montrichardia are among the most remarkable emergent macrophytes in tropical wetlands. It occurs exclusively in the Neotropics and contains two living species, M. linifera (Arruda) Schott and M. arborescens (L.) Schott. Montrichardia linifera has been reported mainly in the Amazon basin (southern Venezuela to Guyana, Brazil, Ecuador and Peru), whereas M. arborescens occurs in Central America (Mexico to Panama), the Lesser Antilles and northern South America. Based on our review of herbarium specimens from Central America and Colombia, as well as field documentation in Panama, we hereby provide the first report of the occurrence of M. linifera in Panama, Central America and western Colombia. Furthermore, this finding represents the first record on the Pacific Slope for this species in the Neotropics. The habitat, ecology, life-form, taxonomic remarks and morphological characteristics of the species are presented, discussed and illustrated. Additionally, a key for the species of the genus Montrichardia is included; we also provide a discussion about the helophyte concept for the genus Montrichardia.
