This book was released on 2004 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The fluvial style and syntectonic deposition of conglomerate in the upper part of the Nanushuk Formation are resolved using facies architectural analysis and structural geometry. Along the Kanayut River in the northern foothills of the Brooks Range, Alaska, fluvial conglomerate is exposed as benches on the north and south flanks of the Arc Mountain anticline. Photo mosaics of each bench on the north side, along with thirty-three detailed measured sections, were used to evaluate facies architecture. Eight lithofacies were described that characterize six facies associations including longitudinal and transverse gravel bars, diffuse gravel sheets, sediment gravity flow deposits, crevasse splay and floodplain deposits, and scour fills of a gravel-bed braided river. Strata on the south limb of the anticline show characteristics of syndeformational deposition during the growth of the south limb of the Arc Mountain anticline. These structural data provide new evidence for syndepositional contractional deformation during the mid-Cretaceous at this locality in the northern foothills of the Brooks Range. These results provide clues to the character and extent of potential reservoir rocks from the Nanushuk Group that are present in the subsurface of the National Petroleum Reserve in Alaska, which is important for continued recovery of natural resources on the North Slope"--Leaf iii.

This book was released on 2005 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to present the results of a sedimentological study of Aptian-to Albian-age Nanushuk Formation rocks along the north limb of the Arc Mountain anticline at the Kanayut River, Alaska. The goal of this study is to define and interpret lithofacies and architectural elements for the conglomerate in the study area, and then use these interpretations to suggest a fluvial model for the river that deposited the conglomerate.
Book Synopsis Structural Geology of the Big Bend Anticline, Brooks Range Foothills, Alaska by : Cheryl M. Sanders
Download or read book Structural Geology of the Big Bend Anticline, Brooks Range Foothills, Alaska written by Cheryl M. Sanders and published by . This book was released on 2014 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big Bend anticline is near the northern edge of the Brooks Range foothills of northern Alaska. The structure of the foothills is a low-taper triangle zone or passive-roof duplex within Brooks Range foreland basin deposits. The dominant structures are detachment folds locally cut by thrust faults and Big Bend anticline is one of these. This research combines detailed surface mapping (1:25,000) with interpretation of aerial photos and satellite imagery of the Big Bend anticline and seismic reflection data from the Umiat anticline to reconstruct its surface and subsurface geometry. The research area surrounds the Big Bend of the Chandler River and covers approximately 10 km2. The mechanical stratigraphy of the area consists of the competent Nanushuk sandstones between two incompetent units-the overlying Seabee and underlying Torok shales. The structure of the area consists of an east-trending anticline with a hinge that branches westward into two open, broad anticlines and an intervening syncline. A forethrust near the southern hinge and a backthrust near the northern hinge have broken through the anticline west of the branch point. Subsurface data of Umiat anticline combined with surface projected cross sections from the study area provide an analog of the subsurface structure in the Big Bend area. These cross sections show gentle anticlines separated by flat bottomed synclines in competent Nanushuk Formation sandstone. The anticlines overly Torok Formation thickened by north vergent folds and thrust faults above a detachment zone. Collectively, these structures form a low-taper triangle zone. Cross section restoration suggests more shortening in the Torok duplex than in the overlying folds and breakthrough faults. Results of this research provide an analog for other anticlines in the region that are currently the focus of oil and gas exploration.

This book was released on 1998-01-01 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 17 papers presented here introduce results on geological and geophysical research centred largely along a North-South transect through the central Brooks Range of Arctic Alaska. Investigations centre on a descripton of the rocks and their tectonic evolution from the foreland to the hinterland of the orogen, the geometry and kinematics of contractional and extensional structures, regional and local stratigraphic relations, thermochronology, and the deep crustal structure of the Brooks Range and parts of the North Slope, and descriptions of the major lithotectonic assemblages, composing the orogenic belt.

This book was released on 2003 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A new surveying technique was developed to document the geometry of eight km size thrust-related folds in the eastern Brooks Range, Alaska. This method combines data from a theodolite and reflectorless laser rangefinder to construct cross sections that are more precise than those based on field map data. In the study area, weakly to non-metamorphosed Carboniferous carbonates typically form northeast-trending, northwest-vergent, asymmetric thrust-truncated folds. The geometry of most of the folds is consistent with a detachment fold model that allows local thickness changes. The anticlines typically display interlimb angles of less than 90,̊ structurally thickened hinge zones, and overturned forelimbs that dip steeply to moderately, suggesting the folds are over-tightened. Furthermore, structural disruption of bedding in the anticlinal forelimbs suggests that strain was localized in this region of the fold and is interpreted to be a record of the transition from folding to thrust faulting within each fold"--Leaf iii.

This book was released on 2002 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Detailed mapping of a 32 square-kilometer area in the fold-and-thrust belt of the north-central Brooks Range indicates that fault-related folds in the Lisburne Limestone formed as detachment folds and were subsequently cut by thrust faults. Thrust faulting resulted in a duplex structure with a floor thrust in the Kayak Shale and a roof thrust in the Siksikpuk Formation. The linking thrusts of the duplex dip toward the hinterland while the floor and roof thrusts dip toward the foreland indicating that the duplex has been tilted by underlying structures. I constructed models for the sub-lisburne structure to account for the structural geometry observed in the study area. Duplexing of the Kanayut Conglomerate is the most likely cause of the forward tilt, but thickening of the Kayak Shale or deformation beneath the basal thrust of the Endicott Mountains allochthon may also contribute"--Leaf iii.
