Book excerpt: Spherical charges of TNT, each weighing 256 pounds, were exploded at various depths in tuff to determine apparent crater dimensions in a soft rock. No craters were obtained for depths of burst equal to or greater than 13.3 feet. It was deduced that rock fragments were sufficiently large that charges of greater magnitude should be employed for crater experiments intended as models of nuclear explosions.

Available in PDF, EPUB and Kindle. Book excerpt: Aspects of cratering phenomenology are considered along with material properties and shock effects, theoretical cratering mechanics, ejecta, and problems of scaling. Attention is given to the application of high explosion cratering data to planetary problems, cratering mechanisms observed in laboratory-scale high-explosive experiments, nuclear cratering experiments, complex craters in alluvium, terrestrial impact structures, the Ries impact crater, buried impact craters in the Williston basin and the adjacent area, crater morphometry from bistatic radar, a Fourier analysis of planimetric lunar crater shape, a stratigraphic model for Bessel Crater and southern Mare Serenitatis, a nested-crater model of lunar ringed basins, Martian fresh crater morphology and morphometry, the distribution and emplacement of ejecta around Martian impact craters, the nature of the present interplanetary crater-forming projectiles, cratering mechanics and future Martian exploration, the response of rocks to large stresses, the dynamical implications of the petrology and distribution of impact melt rocks, and a review and comparison of hypervelocity impact and explosion cratering calculations.

This book was released on 1988-04-30 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field work, supplemented by laboratory studies, is a cornerstone for the geological sciences. This volume provides an introduction to general field work through selected topics that illustrate specific techniques and methodologies. One hundred and twenty-three main entries prepared by leading authorities from around the world deal with aspects of exploration surveys, geotechnical engineering, environmental management. field techniques, mapping, prospecting, and mining. Special efforts were made to include topics that consider aspects of environmental geology in particular those subjects that involve field inspections related to, for example, the placement of artificial fills, sediment control in canals and waterways, the geologic effects of cities, or the importance of expansive soils to environmental management and engineering. In addition, some widely ranging topics dealing with legal affairs, geological methodology, the scope and organization of geology, report writing, and other concepts, such as those related to plate tectonics and continental drift, provide a necessary perspective to the arena of field geology.

Book excerpt: Apparent crater radius and depth measurements extend HE depth-of-burst charts in desert alluvium to 4. Failure to eject material beyond the crater lip occurs at a depth of burst near 2 1/2.
Download or read book Ejecta Studies written by W. A. Roberts and published by . This book was released on 1963 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project included 146 ejecta measurement stations encircling ground zero at eight radial distances ranging from 373 to 1,707 meters. The twenty-four sampling lines were spaced at fifteen-degree intervals. Data presented were recovered from stations located at radial dis tances of 640, 853, 1,067, 1,280, and 1,707 meters. An attempt will be made to recover data at stations located closer to ground zero at a later time. Preliminary analysis of ejecta data indicates that a real density varies inversely as distance raised to the 3.64 power. Circumfer ential variation of areal density is about a factor of 30 at the 1,707 meter radial distance, a factor of 10 at the 1,280 meter radial dis tance, and a factor of 7 at the 853 meter radial distance.

This book was released on 1974 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Cratering Facility was designed and constructed for the purpose of performing laboratory-scale, high-explosive cratering experiments. Fifty-five events were conducted in which centrally initiated, spherical, lead-azide charges were detonated in dry Ottawa sand. Charge configurations for these events ranged from 5-charge-radii height of burst to 15-charge-radii depth of burst. The techniques required to maintain a well characterized 'standard' sandbed were developed and employed for two series of experiments. The 'standard' sandbed was chosen to be that with an in-situ density of 1.801 gm/cc. The main or Overall Series of experiments was conducted in the 'standard' sandbed to determine the relationship between apparent crater size and charge configurations. Realistic levels of reproducibility for various cratering experiments, in terms of apparent crater dimensions, were determined by conducting a Benchmark Series of experiments.
