“…The low heat £ow in the North Limo¤ n Basin can be explained by the lack of a rift-phase. The crustal variations observed by Munoz et al (1997) may explain the decrease in the geothermal gradient in that area.The basins further to the south in Costa Rica and Panama are exclusively underlain by basaltic crust. Another possible explanation for the low heat £ow is given by the nature of the underlying lithosphere.…”

The Limo¤ n back-arc basin belongs to the southern Central American arc-trench system and is situated at the east coast of Costa Rica.The basin-¢ll consists of Late Cretaceous to Pleistocene sedimentary rocks. A northern and a southern sub-basin can be de¢ned, separated by the E^Wtrending Trans Isthmic Fault System.The North Limo¤ n Basin is nearly undeformed, whereas the South Limo¤ n Basin is characterized by a fold-and-thrust belt. Both sub-basins have a very similar sedimentary ¢ll and can act as a natural laboratory for reconstructing controlling factors of arcrelated sedimentary basins as well as the in£uence of deformation on a basin system. Modelling focused on burial history and temperature evolution.Two -dimensional simulations were carried out with the software PetroMod s .The geohistory curve of the North Limo¤ n Basin is overall linear, indicating continuous subsidence.The South Limo¤ n Basin is also characterized by continuous subsidence, but rates strongly increased at the beginning of the Neogene. Despite a rapid Plio -Pleistocene deformation of the fold-and-thrust belt, the present-day temperature ¢eld is not disturbed in that area.The modelling results indicate a mean heat £ow of 60 mWm À 2 for the North Limo¤ n Basin and 41mWm À 2 for the South Limo¤ n Basin.These values are low compared with other back-arc basins.The lower values are attributed to the following e¡ects: (1) underlying basaltic crust, (2) the lack of an initial rift phase, (3) the low extension rates, (4) absence of volcanic activity and (5) insulation e¡ects of a thick sediment pile.The reasons for the locally lower heat £ow in the southern sub-basin can be found in the low-angle subduction of the Cocos Ridge. Owing to the low subduction angle, the cool fore-arc mantle-wedge below the island-arc is pushed backwards increasing the cooled area.

From incipient island arc to doubly‐vergent orogen: A review of geodynamic models and sedimentary basin‐fills of southern Central America

Island Arc

View full text Add to dashboard Cite

Southern Central America is a Late Mesozoic/Cenozoic island arc that evolved in response to the subduction of the Farallón Plate beneath the Caribbean Plate in the Late Cretaceous and, from the Oligocene, the Cocos and Nazca Plates. Southern Central America is one of the best studied convergent margins in the world. The aim of this paper is to review the sedimentary and structural evolution of arc‐related sedimentary basins in southern Central America, and to show how the arc developed from a pre‐extensional intra‐oceanic island arc into a doubly‐vergent, subduction orogen. The Cenozoic sedimentary history of southern Central America is placed into the plate tectonic context of existing Caribbean Plate models. From regional basin analysis, the evolution of the southern Central American island arc is subdivided into three phases: (i) non‐extensional stage during the Campanian; (ii) extensional phase during the Maastrichtian‐Oligocene with rapid basin subsidence and deposition of arc‐related, clastic sediments; and (iii) doubly‐vergent, compressional arc phase along the 280 km long southern Costa Rican arc segment related to either oblique subduction of the Nazca plate, west‐to‐east passage of the Nazca–Cocos–Caribbean triple junction, or the subduction of rough oceanic crust of the Cocos Plate. The Pleistocene subduction of the Cocos Ridge contributed to the contraction but was not the primary driver. The architecture of the arc‐related sedimentary basin‐fills has been controlled by four factors: (i) subsidence caused by tectonic mechanisms, linked to the angle and morphology of the incoming plate, as shown by the fact that subduction of aseismic ridges and slab segments with rough crust were important drivers for subduction erosion, controlling the shape of forearc and trench‐slope basins, the lifespan of sedimentary basins, and the subsidence and uplift patterns; (ii) subsidence caused by slab rollback and resulting trench retreat; (iii) eustatic sea‐level changes; and (iv) sediment dispersal systems.

The southern Central American active margin is a world-class site where past and present subduction processes have been extensively studied. Tectonic erosion/accretion and oblique/orthogonal subduction are thought to alternate in space and time along the Middle American Trench. These processes may cause various responses in the upper plate, such as uplift/subsidence, deformation, and volcanic arc migration/shut-off. We present an updated stratigraphic framework of the Late Cretaceous-Cenozoic Sandino Forearc Basin (SFB) which provides evidence of sedimentary response to tectonic events. Since its inception, the basin was predominantly filled with deep-water volcaniclastic deposits. In contrast, shallow-water deposits appeared episodically in the basin record and are considered as tectonic event markers. The SFB stretches for about 300 km and varies in thickness from 5 km (southern part) to about 16 km (northern part). The drastic, along-basin, thickness variation appears to be the result of (1) differential tectonic evolutions and (2) differential rates of sediment supply. (1) The northern SFB did not experience major tectonic events. In contrast, the reduced thickness of the southern SFB (5 km) is the result of at least four uplift phases related to the collision/accretion of bathymetric reliefs on the incoming plate: (i) the accretion of a buoyant oceanic plateau (Nicoya Complex) during the middle Campanian; (ii) the collision of an oceanic plateau (?) during the late Danian-Selandian; (iii) the collision/accretion of seamounts during the late Eocene-early Oligocene; (iv) the collision of seamounts and ridges during the Pliocene-Holocene. (2) The northwestward thickening of the SFB may have been enhanced by high sediment supply in the Fonseca Gulf area which reflects sourcing from wide, high relief drainage basins. In contrast, sedimentary input has possibly been lower along the southern SFB, due to the proximity of the narrow, lowland isthmus of southern Central America. Moreover, two phases of strongly oblique subduction affected the margin, producing strike-slip faulting in the forearc basin: (1) prior to the Farallon Plate breakup, an Oligocene transpressional phase caused deformation and uplift of the basin depocenter, triggering shallowing-upward of the Nicaraguan Isthmus in the central and northern SFB; (2) a Pleistocene--
