The architecture, growth and tectono-stratigraphic significance of rift-oblique lineaments on the NE Atlantic Margin
… seismometer datasets, a series of rift-oblique lineaments (loosely referred to as ‘transfer zones’) have been identified which are commonly inferred to compartmentalise and laterally offset structural highs and depocentres developed within the Mesozoic – Cenozoic rift basins. A range of …

Sub-Surface Structural Analysis of the Appalachian Basin in Morrow County, Ohio
… maps indicating potential faults (i.e., lineaments), and correlate those lineaments to the four consecutive orogenies spanning from Early Cambrian through Permian time in the Appalachian Basin.</p> <p>Nine lineaments trending in a northwest-southeast orientation and five lineaments …

Multiple data set integration and GIS techniques used to investigate linear structural controls in the southern Powder River Basin, Wyoming
Lineaments in the Powder River Basin were mapped and categorized from Landsat TM imagery, a Digital Elevation Model (30 m), and Digital Line Graph (DLG) hydrology files. A GIS program was written using DLG information to eliminate those lineaments that were within 20° of roads and railroads. …

Borders and Bandaids
… of the walls and geopolitical lines—or lineaments. It is therefore crucial to comprehend the concept of lineaments on every scale, as it is the base idea that permeates all design. It is design in its purest form. The following architectural argument will explore Leon Battista Albert's …

Comparative Lineament and Geomorphic Analysis of Chaotic Terrains and Noctis Labyrinthus, Mars
… topographic highs are bounded by low troughs. Lineaments, topography, and geomorphology of NL and chaotic terrains were analyzed to determine tectonics and fluid influence in the formation and evolution of both sites. NL shows preferential fracture patterns associated with regional extension. …

The structural setting of the Canaã dos Carajás region and Sossego-Sequeirinho deposits, Carajás – Brazil
… (1) identification of crustal scale regional lineaments and their relationship with mineral deposits; (2) a new tectonic framework and structural model for the Canaã dos Carajás region; and (3) description and interpretation of the structural framework of the Sossego and Sequeirinho mines. The …

Geologic controls on mass movement in the New River Gorge, West Virginia
… factors, such as bedrock lithology, joints, lineaments, and attitude of bedding were analyzed and evaluated for influences on mass-movement in the New River Gorge. Mass-movement deposits were mapped at a 1:24,000 scale in three study areas within the gorge and a Geographic Information System …

Structure Segmentation and Transfer Faults in the Marcellus Shale, Clearfield County, Pennsylvania: Implications for Gas Recovery Efficiency and Risk Assessment Using 3D Seismic Attribute Analysis
… and thrusts, cross-regional, northwest-trending lineaments were mapped. These lineaments may pose a threat to hydrocarbon productivity and recovery efficiency due to faults and fractures acting as paths of least resistance for induced hydraulic stimulation fluids. These lineaments may represent …

Delineating of the Utica Shale/Point Pleasant Formation Play System to Determine Influence of the Precambrian Basement in Northeastern Ohio
… is not fully agreed upon. Precambrian faults and lineaments are known to exist and have been mapped, but are thought to have ceased their influence on deposition by the time of the Knox unconformity during the Cambrian. In the case of the Ordovician Utica Shale, Point Pleasant Formation, Trenton …

Interprétation structurale des linéaments par traitement d'image satellitaire : cas des sous-provinces d'Abitibi et d'Opatica (Québec)
… the results of the interpretation of the lineaments within the Abitibi and Opatica Subprovinces. These results were extracted from processed satellite images and compared to geoscientific data in a geographie information system (GIS). The simple methodological approach, based on the …

The geologic and tectonic evolution of the Pan-African/Mozambique Belt in East Africa
… This study shows that the major lineaments identified in the Horn of Africa trend 010 ± 100, 055-065° and 145-165°. The 010 ± 10° and 145-165° trending lineaments form conjugate sets, while a later deformation episode reactivated 145-165° (NW-SE) trending lineaments and caused …

Geophysical investigations in the English Lake District
… three important ENE-trending geophysical lineaments across the Lake District (the Crummock, Ullswater and Southern Borrowdales lineaments). Several prominent, but less extensive, NE-trending lineaments are also visible across the central and western parts of the area. The ENE-trending set …

Fracture-enhanced porosity and permeability trends in the Bakken Formation, Williston Basin, western North Dakota
… related to fracturing. </p><p> In theory, lineaments mapped on the surface reflect the geometry of basement blocks and the zones of fracturing propagated upward from them. Fracturing in the Williston Basin is thought to have occurred along reactivated basement-block boundaries in response …

Interplay of porous media and fracture stimulation in sedimentary enhanced geothermal systems : Red River Formation, Williston Basin, North Dakota
… correlative relationship between the surface lineaments and the basement faults in the study area. Consequently, the orientations and locations of the surface lineaments and basement faults were combined in a shapefile to represent the area’s discrete fracture network. In the future, the …

Patterns and mechanisms of heat transport in the northern Denver Basin Nebraska, South Dakota and Wyoming
… flux and the presence of faults and structural lineaments mapped in the region. Geothermal, hydrogeological, lithological, and structural data available for the northern Denver Basin were compiled and analyzed in an effort to determine the hydrothermal mechanisms responsible for observed heat …

Linear Trend Analysis: Implications for a Structural Fracture System and Applications of Subsurface Fluid Migration, Northwest Arkansas and Eastern Oklahoma
<p>Lineaments are mappable, simple or composite linear or curvilinear features of the Earth’s surface longer than one mile, which differ from the patterns of adjacent features and are presumed to reflect subsurface phenomenon such as faults and fractures. The usage of the term refers to the …

Investigation of factors influencing borehole yields in the Nzhelele-Makhado Area in Limpopo Province, South Africa
… which recharges and discharges locally. Mapped lineaments are slightly low yielding (average yield of 0.32 l/s) compared to the faults (average yield of 0.43 l/s) within the study area. Boreholes drilled along the NE-SW trending lineaments support double the yields (0.41 l/s) on average of those …
