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

Irregular plate boundary controls on Foreland Basin sedimentation (Miocene, Kahramanmaraş Foreland Basin, SE Turkey)

“…1; Robertson et al, 2004). The oblique wedge-top basin on the overlying plate and sedimentation on irregular plate part in the Kahramanmaras ß Foreland Basin are the main differences between this obliquely collided area and the recent oblique collision area in the Caribbean region (Garciacaro et al, 2011;Gül et al, 2012). A theoretical Fig.…”

“…The structural properties of the foreland basin control the depocentre geometry, lithological properties and facies differentiation (Lomas and Joseph, 2004;Gül et al, 2011Gül et al, , 2012. However, the oblique collision of plates because of the presence of irregular plate boundaries may cause the development of small wedge-top basins and may include a variety of ponded or otherwise confined turbidite sediments; either single or multiple sourced systems with numerous facies changes (Garciacaro et al, 2011;Gül et al, 2012).…”

Sand Distribution along Shelf-Edge Deltaic Systems: A Case Study from Eastern Offshore Trinidad

“…There are a variety of tectonic models that try to explain the tectonostratigraphic evolution of the southeastern Caribbean region (Speed, 1985;Robertson and Burke, 1989;Russo and Speed, 1992;Baab and Mann, 1999;Flinch et al, 1999;Pindell and Keenan, 2001;Garciacaro, 2009). Despite the abundance of different theories, the details associated with the tectonic evolution of this region are still not completely understood.…”

“…Most of the existing models include a combination of interpretations that fall in one of the following categories (Baab and Mann, 1999;Garciacaro et al, 2009): (1) oblique collision and thrusting (Speed, 1985;Russo and Speed, 1992) (2) strike-slip faulting motion as dominant mechanism (Robertson and Burke, 1989;Babb and Mann, 1999;Flinch et al, 1999), (3) tectonically-controlled normal faulting related to strike-slip faulting (pull-apart basins) as the dominant process (Pindell and Keenan, 2001). …”
