Basin-scale architecture of deeply emplaced sill complexes: Jameson Land, East Greenland
Eide, Christian Haug; Schofield, Nick; Jerram, Dougal Alexander; Howell, John Anthony (Peer reviewed; Journal article, 2016)Igneous sills are common components in rifted sedimentary basins globally. Much work has focused on intrusions emplaced at relatively shallow palaeodepths (0 – 1.5 km). However, owing to constraints of seismic reflection ... -
Direct image-to-geometry registration using mobile sensor data
Kehl, Christian; Buckley, Simon John; Gawthorpe, Robert; Viola, Ivan; Howell, John Anthony (Peer reviewed; Journal article, 2016)Adding supplementary texture and 2D image-based annotations to 3D surface models is a useful next step for domain specialists to make use of photorealistic products of laser scanning and photogrammetry. This requires a ... -
Distribution of discontinuous Mudstone beds within wavedominated shallow-marine deposits: Star point sandstone and blackhawk formation, Eastern Utah
Eide, Christian Haug; Howell, John Anthony; Buckley, Simon John (Journal article; Peer reviewed, 2014)Deposits of wave-dominated shorelines are typically considered to act as relatively simple hydrocarbon reservoirs and are commonly modeled as “tanks of sand.” However, important heterogeneities that can act as barriers to ... -
LIME: Software for 3-D visualization, interpretation, and communication of virtual geoscience models
Buckley, Simon John; Ringdal, Kari; Naumann, Nicole; Dolva, Benjamin; Kurz, Tobias Herbert; Howell, John Anthony; Dewez, Thomas J.B. (Peer reviewed; Journal article, 2019-01-10)The use of three-dimensional (3-D), photo-textured representations of topography from laser scanning and photogrammetry is becoming increasingly common across the geosciences. This rapid adoption is driven by recent ... -
Linking the high-resolution architecture of modern and ancient wave-dominated deltas: Processes, products, and forcing factors
Ainsworth, R. Bruce; Vakarelov, Boyan K.; Eide, Christian Haug; Howell, John Anthony; Bourget, Julien (Peer reviewed; Journal article, 2019)Wave-dominated deltas are often fed by single trunk distributary channels which can remain the primary source of sediment supply to the delta for periods of thousands of years. Consequently, the sedimentary architecture ... -
Sedimentology and reservoir properties of tabular and erosive offshore transition deposits in wave-dominated, shallow-marine strata: Book cliffs, USA
Eide, Christian Haug; Howell, John Anthony; Buckley, Simon John (Journal article; Peer reviewed, 2015)Facies models for wave-dominated shorelines include an ‘offshore transition zone’ between shelfal mudstones and nearshore shoreface sandstones. Offshore transition-zone deposits are commonly tabular sandstone beds interbedded ... -
Seismic interpretation of sill complexes in sedimentary basins: Implications for the sub-sill imaging problem
Eide, Christian Haug; Schofield, Nick; Lecomte, Isabelle; Buckley, Simon John; Howell, John Anthony (Journal article; Peer reviewed, 2018)Application of 3D-seismic reflection-data to igneous systems in sedimentary basins has led to a revolution in the understanding of mafic sill-complexes. However, there is considerable uncertainty on how geometries and ... -
Transport of mafic magma through the crust and sedimentary basins: Jameson Land, East Greenland
Eide, Christian Haug; Schofield, Nick; Howell, John Anthony; Jerram, Dougal Alexander (Journal article; Peer reviewed, 2021)Igneous sheet-complexes transport magma through the crust, but most studies have focused on single segments of the magma transport system or have low resolution. In the Jameson Land Basin in East Greenland, seismic reflection ...
