Book Synopsis Pressure and Gravity Effects on the Simulation of Meteorite Impact Craters by : Jerry Alan Smith
Download or read book Pressure and Gravity Effects on the Simulation of Meteorite Impact Craters written by Jerry Alan Smith and published by . This book was released on 1967 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meteorite impact craters were simulated by detonation of chemical explosives in a cohesionless medium at various air pressures (0.0005 mm Hg to 1000 mm Hg) and at four gravity conditions (0.17 g, 0.38 g, 1.0 g, and 2.5 g). Crater parameters (diameter and depth) were measured to determine the effects of pressure and gravity on the cratering process. Lip height was measured only in the pressure work. Diameter and depth increased approximately 12% and 10% respectively with decreasing pressure while lip height remained relatively constant. Crater diameter decreased from a mean value of 47.9 cm at 0.17 g to 33.7 cm at 2.5 g. Depth did not vary appreciably from 1.0 g to 2.5 g (7.7 cm to 5.7 cm). A scaling equation was derived to relate crater diameter, pressure, gravity, and energy in a cohesionless medium within the pressure range of 300 mm Hg to 1000 mm Hg and the gravity range of 0.17 g to 2.5 g. To obtain additional information on the mechanics of crater formation, craters were formed in mediums with horizontal layering. Scouring and compaction were found to be predominant processes in both the pressure and gravity phases. (Author).

Book Synopsis Cratering in Marine Environments and on Ice by : Henning Dypvik
Download or read book Cratering in Marine Environments and on Ice written by Henning Dypvik and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their global importance, little is known about the few existing examples of impacts into marine environments and icy targets. They are among the least understood and studied parts of impact crater geology. The icy impacts are also of great importance in understanding the developments of the outer planets and their satellites such as Mars or Europa. Furthermore, the impact mechanisms, crater formation and collapse, melt production and the ejecta distribution are scarcely known for impact on targets other than the "classical" solid silicates of the continental crust. The reaction of water and ice to impacts clearly deserves a more thorough study. The understanding of impact effects and consequences in the case of aqueous hits, soft sediments and icy targets has not been thoroughly explored and comprises the main focus of this book. A number of papers in the field of hypervelocity impacts on ice are included. These cover a review of available literature in the field of laboratory studies of such impacts, large impact structures on Titan, predicting impact cratering on a comet nucleus, and a novel report on the survival of bacteria fired at hypervelocity into icy surfaces. This latter paper is concerned with astrobiology and in particular Panspermia (natural migration of life through space).
