Tektites in the Geological Record


Book Description

This text commences with the history of tektites, from mediaeval China, through finds in Czechoslovakia in the 18th century and Darwin's description while on the Beagle, to 20th-century finds in South East Asia, the Ivory Coast and the USA. The four major strewn fields are described, followed by their extension by deep sea finds of microtektites and the recognition of irregular, large layered tektites in SE Asia.

Large Meteorite Impacts and Planetary Evolution


Book Description

Comprises 28 papers which grew out of the International Conference on Large Meteorite Impacts and Planetary Evolution, August/September, 1992 in Sudbury, Ontario. The interdisciplinary papers, encompassing diverse studies from trace element geochemistry to planetary exploration, are arranged into f




Aerodynamic Evidence Pertaining to the Entry of Tektites Into the Earth's Atmosphere


Book Description

Evidence is presented which shows that the Australian and Java tektites entered the earth's atmosphere and experienced ablation by severe aerodynamic heating in hypervelocity flight. The laboratory experiments on hypervelocity ablation have reproduced ring-wave flow ridges and coiled circumferential flanges like those found on certain of these tektites. Systematic striae distortions exhibited in a thin layer beneath the front surface of australites also are reproduced in the laboratory ablation experiments, and are shown to correspond to the calculated distortions for aerodynamic ablation of a glass. About 98 percent of Australian tektites represent aerodynamically stable configurations during the ablative portion of an entry trajectory. Certain meteorites exhibit surface features similar to those on tektites.

Springer Handbook of Glass


Book Description

This handbook provides comprehensive treatment of the current state of glass science from the leading experts in the field. Opening with an enlightening contribution on the history of glass, the volume is then divided into eight parts. The first part covers fundamental properties, from the current understanding of the thermodynamics of the amorphous state, kinetics, and linear and nonlinear optical properties through colors, photosensitivity, and chemical durability. The second part provides dedicated chapters on each individual glass type, covering traditional systems like silicates and other oxide systems, as well as novel hybrid amorphous materials and spin glasses. The third part features detailed descriptions of modern characterization techniques for understanding this complex state of matter. The fourth part covers modeling, from first-principles calculations through molecular dynamics simulations, and statistical modeling. The fifth part presents a range of laboratory and industrial glass processing methods. The remaining parts cover a wide and representative range of applications areas from optics and photonics through environment, energy, architecture, and sensing. Written by the leading international experts in the field, the Springer Handbook of Glass represents an invaluable resource for graduate students through academic and industry researchers working in photonics, optoelectronics, materials science, energy, architecture, and more.
