Miocene-to-recent structure and basinal architecture along the Central Range strike-slip fault zone, eastern offshore Trinidad

Regional structure and tectonic history of the obliquely colliding Columbus foreland basin, offshore Trinidad and Venezuela

“…A fourth trend that converges on the Columbus basin is marked by a broad zone of east-west to east-northeast-striking, rightlateral strike-slip faults formed along the southern margin of the Caribbean plate and curving abruptly to the northeast near the east coast of Trinidad (Soto, 2007;Soto et al, in press). These strike-slip faults are associated with a group of late Neogene open folds with axial traces trending east-northeast (Babb and Mann, 1999).…”

“…The location and character of faults in the area were compiled fromYsaccis (1997),Robertson and Burke (1989), Di Croce et al (1999),Babb and Mann (1999),Audemard (2000),Wood (2000),Deville et al (2003) ,Soto (2007), andSoto et al (in press). Basins are labeled NCB (North Coast basin), NR (Northern Range), NB (Northern basin), CR (Central Range), DR (Darien ridge of eastern offshore Trinidad), SB (Southern basin), SR (Southern Range), CC (Columbus channel), GR (Galeota ridge), CB (Columbus basin landward of the shelf edge), and CBDW (Columbus basin deepwater area seaward of the shelf edge).…”

Gravity and magnetic field characteristics and hydrocarbon prospects of the Tobago Basin

“…; Aitken et al . ); very few studies have been conducted on the structural framework and characteristics of the basin as a whole (Speed ; Speed, Torrini and Smith ; Speed and Smith‐Horowrrz ; Soto, Mann and Escalona ). In this study of the structure of the Tobago Basin, we utilised shipborne‐ and satellite‐measured gravity data, shipborne‐measured magnetic data, and aeromagnetic survey data (all data were provided by GETECH) along with information from other studies to analyse the structural configuration and basement characteristics of the basin and identify likely hydrocarbon exploration prospects.…”

“…The results of these seismic campaigns have provided important information for understanding basin development and the selection of future well locations. However, studies concerning the distribution of wells, seismic lines, structural framework, and other features of the basin have focused mainly on a small area in the southwestern portion of the basin near Trinidad and Tobago (Christeson et al 2008;Aitken et al 2011); very few studies have been conducted on the structural framework and characteristics of the basin as a whole (Speed 1985;Speed, Torrini and Smith 1989;Speed and Smith-Horowrrz 1998;Soto, Mann and Escalona 2011). In this study of the structure of the Tobago Basin, we utilised shipborne-and satellite-measured gravity data, shipborne-measured magnetic data, and aeromagnetic survey data (all data were provided by GETECH) along with information from other studies to analyse the structural configuration and basement characteristics of the basin and identify likely hydrocarbon exploration prospects.…”

Structural controls on Quaternary deepwater sedimentation, mud diapirism, and hydrocarbon distribution within the actively evolving Columbus foreland basin, eastern offshore Trinidad

“…The Orinoco River has been the primary source of sediment for the foreland basins in eastern Venezuela and the Trinidad area since the early Miocene (Diaz de Gamero, 1996). Following a period of folding and thrusting that culminated in the middle Miocene, a period of protracted transpression and right-lateral strike-slip faulting affected the area up to the present-day (Weber et al, 2001(Weber et al, , 2010Soto, 2007;Soto et al, 2007;Soto et al, 2010).…”
