Available in PDF, EPUB and Kindle. Book excerpt: This volume is a compilation of the newer techniques of refraction seismic surveying. It contains a series of articles written principally by members of SEG who are specialist in refraction techniques. The volume contains only new materials with a bibliography of references to other refraction materials available. The majority of the papers are of a "technique type" which describe some particular interpretation technique that may be used for better interpretation of special refraction data.

This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic refraction method was used to delineate the stratigraphic units and the water table within a glacial setting in McLean County (IL). Five seismic surveys were conducted at the T3 and the Little Kickapoo Creek (LKC) research sites, from September to November 2016. Seismic data were interpreted using the Rayfract tomography software, and reference velocities were calculated using Sesistronix. All surveys resulted in a three layers case with distinct reference p-wave velocities. These seismic layers correlate with the stratigraphic units described at the respective sites. However, the interpreted thicknesses are larger than the observed. The first refractor on the travel time curves was interpreted as the water table. Predicted depth to the water table ranged from 0.6 m above to 1.1m below the observed depth; with 10.5% of the predictions greater than 0.5 m above the observed, 21.1% greater than 0.5 m below the observed, and 68.4% within 0.5 m of the observed water table depth. Overall, predicted depths to the water table are deeper than the observed, with the exception of wells that are closest to the diversion tiles. The accuracy of the predictions were higher at LKC site (14.7% error) than at T3 site (46.3% error).

Download or read book Determinantion of Vp Vs Glacial Drift Thickness and Poisson s Ratio at a Site in Jay County Indiana Using Seismic Refraction and Multichannel Analysis of Surface Wave MASW Analysis on a Common Data Set written by Shamim Ahammod and published by . This book was released on 2015 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 2013, an industry-scale seismic reflection survey was conducted at a site in northern Jay County, Indiana, by geophysics students and faculty of Wright State University. As a part of that effort, a separate near-surface seismic dataset was collected to examine the Vp, Vs, and Poisson’s Ratio of the glacial drift and upper bedrock. This near-surface study successfully used a common dataset that was separately analyzed for both Vp (seismic refraction) and Vs (MASW) to calculate the Poisson’s Ratio of the glacial drift and underlying bedrock. The driller’s log for a water well near the east end of this near-surface survey indicates glacial drift (unconsolidated clay and sand) overlies limestone bedrock at a depth of 110 feet. Water wells in the broader area show bedrock depth varying from 110 to 122 feet, but locally as much as 140 feet. The near-surface seismic data were acquired using a Bison EWG (Elastic Wave Generator) assisted weight drop source that shot every station through a stationary spread of 48 channels using a pair of 24-channel Geode seismographs. Each channel recorded a a single vertical 4.5 Hz geophone at a station spacing of 10 feet. Four weight drop records at each source point were summed to enhance the S/N ratio. The same data volume was processed both for Vs using SurfSeis3 MASW (Multichannel Analysis of Surface Wave) software and for Vp using IXRefrax3 refraction software. The MASW results suggest that the depth to bedrock at the survey location ranges from 115-120 feet (~35 m) with Vs of 1,200-2,000 ft/sec (366-610 m/s) for glacial drift and 2,400-2,700 ft/sec (730-823 m/s) for bedrock. The P-wave refraction results suggest the depth to bedrock ranges from 118-122 feet (36-37 m) with average Vp of ~5,000 ft/sec (1,524 m/s) for glacial drift and ~17,000 ft/sec (5180 m/s) for limestone bedrock. The Poisson’s Ratio for the glacial drift calculated using the Vp and Vs at common locations in this study is 0.470-0.473, which is consistent with published results elsewhere. This study suggests that Poisson’s ratio can be determined using velocities from different analysis methods on the same dataset with good results.

This book was released on 1966 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A seismic-refraction survey was conducted in the vicinity of the Cumberland Plateau Observatory, Tennessee, (C.P.O.) in June and July 1965, to determine the velocities of seismic waves in the crust and upper mantle and the crustal structure. A total of 1300 km of reversed seismic -refraction coverage was obtained along two profiles which intersect at the observatory. Each profile is approximately 400 km in length. The velocity of seismic waves is 6.1 km/sec (P sub g) in the upper crustal layer, 6.7 km/sec (P*) in the intermediate layer, and 8.0 km/sec (P sub n) or slightly higher in the upper mantle. The depth to the intermediate layer varies from 6.3 km to 14.5 km. The Mohorovicic discontinuity dips toward the south from depths of 35 km in southern Kentucky near Fort Campbell, and Burnside, to depths of 45 km near Gainesville, Georgia, and 51 km near Moulton, Alabama. The preferred crustal model at C.P.O. is: H sub 1 = 12 km, (V sub 1 = 6.1 km/sec) H sub 2 = 28 km (V sub 2 = 6.7 km/sec) for a total crustal thickness of 40 km, with an upper-mantle velocity of 8.0+ km/sec.
