ABSTRACT This paper delineates our use of 10 708 km 2 three‐dimensional (3D) seismic data from the continental margin Trinidad and Tobago West Indies to describe a series mass transport complexes (MTCs) that were deposited during Plio‐Pleistocene. area, situated along obliquely converging boundary Caribbean/South American plates proximal Orinoco Delta, is characterized by catastrophic shelf‐margin processes, intrusive/extrusive mobile shales active tectonism. Extensive mapping different...
Mass-transport complexes (MTCs) form a significant component of the stratigraphic record in ancient and modern deep-water basins worldwide. One such basin, deep-marine margin eastern offshore Trinidad, situated along obliquely converging boundary Caribbean South American plates proximal to mouth Orinoco River, is characterized by catastrophic shelf-margin processes, intrusive extrusive mobile shales, active tectonics, possible migration sequestration hydrocarbons. Major structural elements...
ABSTRACT Mass‐transport complexes undergo fabric modification during emplacement that results in the alignment of elongated grains. Grain‐fabric alignments promote mechanical and petrophysical anisotropy, which has broad implications for hydrocarbon extraction, carbon sequestration geohazard assessment. These are likely more pronounced mass‐transport with carbonate components, where proportion grains can be much higher as compared to siliciclastic complexes. However, characteristics...
Abstract Seismic geomorphology, the extraction of geomorphic insights using predominantly three-dimensional seismic data, is a rapidly evolving discipline that facilitates study subsurface plan view images. A variety analytical techniques employed to image and visualize depositional elements other geologically significant features.

Mass-transport deposits (MTDs) are gravity-induced units that represent an important component of modern and ancient deep-water stratigraphic successions. MTDs have been widely documented in the literature, but a comprehensive compilation quantitative morphometric parameters associated with their external architecture is still lacking. This work presents database contains 332 data points document length, area, volume, thickness from different geologic ages variety continental margins around...
Abstract Landslides are common in aquatic settings worldwide, from lakes and coastal environments to the deep sea. Fast-moving, large-volume landslides can potentially trigger destructive tsunamis. damage disrupt global communication links other critical marine infrastructure. Landslide deposits act as foci for localized, but important, deep-seafloor biological communities. Under burial, landslide play an important role a successful petroleum system. While broad importance of understanding...

Abstract Lidar collects high-resolution spatial data, making it a popular tool for outcrop investigations; however, few of these studies utilize lidar’s spectral capability. scanners commonly collect intensity returns (power returned/power emitted) that are influenced primarily by distance and target reflectivity, with lesser influence from angle incidence, roughness, environmental conditions. Application normalization results in values approximate reflectivity. At the near-infrared...
Abstract Quantitative seismic geomorphology (QSG) is a new direction in the analysis of data that will create step-change our knowledge, characterization, and understanding older clastic environments. QSG defined as quantitative landforms, imaged 3-D data, for purposes history, processes, fill architecture basin. Built upon foundation stratigraphy sequence stratigraphy, uses integrated with core logs to investigate nature reservoirs through collection on morphometrics, analyses spatial...
ABSTRACT Mixed siliciclastic–carbonate mudrocks have variable depositional processes and diagenetic pathways, creating mineralogical complexity thus difficulty in characterizing reservoir quality using typical subsurface datasets (e.g., well logs) as conventional visual core-description techniques. Core-based X-ray fluorescence (XRF) data quantifies subtle elemental variations that can aid interpreting fine-scale sedimentological packages reservoir-property distribution. XRF has proven to be...
ABSTRACT Recent studies suggest that mass‐transport complexes can be vertically compartmentalized (i.e. contain multiple internal units or sub‐units), either by amalgamation of successive mass failures shear within a single failure event. While this compartmentalization has been documented in seismic studies, comprehensive characterization at the sub‐seismic (outcrop) scale is still lacking. Limited understanding such complexity hampers high‐resolution modelling subsurface. This study...
The Columbus Basin, forming the easternmost part of Eastern Venezuela is situated along obliquely converging margins Caribbean and South American plates. two primary structural elements that characterize basin are (1) transpressional northeast-southwest-trending anticlines (2) northwest-southeast-oriented, down-to-the-northeast, extension normal faults. was filled throughout Pliocene Pleistocene by more than 40,000 ft (>12,200 m) clastic sediment supplied primarily Paleo-Orinoco Delta...
Abstract Discovery of geomorphological elements such as valleys and channel-like features on the surface Mars has prompted debate over alternative origins for these morphologies, including erosion by lava, liquid CO2, glaciation, mass wasting events. Similarities between Martian those certain terrestrial environments suggest that water processes were involved in formation some visible landscapes. Recent advances three-dimensional seismic reflectivity imaging techniques, drawn mainly from oil...
Abstract Submarine mass‐transport deposits are important in many ancient and modern basins. Mass‐transport can play a significant role exploration as reservoir, seal or source units. Although seismic data has advanced the knowledge about these deposits, more outcrop studies needed to better understand gravity mass flows predict properties of their resultant deposits. It is proposed that sufficiently well‐exposed outcrops be divided into three strain‐dominant morphodomains: headwall,...

The effect of the vertical to horizontal permeability ratio ( k v / h ) on many displacement properties is significant, making it an important parameter estimate for reservoir models. Simple ‘streamline’ models have been developed which relate at scale shale geometry, fraction and frequency. A limitation these models, especially tidally-influenced reservoirs, lack quantitisative geological inputs. To address this data, detailed characteristics were measured, using Lidar point clouds, from...
