MOUNTING PROBLEMS IN THE NAMING OF METEORITE DISCOVERIES     

Glenn I. Huss 《Meteoritics & planetary science》1971,6(1):21-25

One of the most important steps in the recovery and study of meteorites is the concise naming of each fall so that confusion of one fall with another is avoided. The presently-used system of naming meteorite falls has been arrived at through an evolutionary process spurred on by necessity. The evolutionary history of the naming of meteorite falls is briefly sketched. Current naming practices are defined and the mounting problems of the present system are discussed. Measures for forestalling growing confusion in the naming of contiguous and overlapping falls, based upon a partial survey of curators of meteorite collections, are presented. A suggestion for the elimination of confusion in the dating of meteorite discoveries is included  相似文献

The Seminole Meteorite was found near Seminole, Texas in 1961 and recognized as a meteorite in 1963. Two fragments weighing a total of 41.1 kg were recovered. Analyses showed these to be fragments of a single black olivine-bronzite, or H4-group chondrite, showing brecciation and a moderate number of individual chondrules  相似文献   

The role of presolar dust in the formation of the solar system     

Gary R. Huss 《Earth, Moon, and Planets》1988,40(2):165-211

Isotopic studies have revealed several types of presolar material in chondritic meteorites (e.g., Ne-E, various components of O, Ti, Ca, Mg). In fact, examples of presolar material are found in all meteorites whose components have not been completely altered by secondary processing. This paper suggests that presolar dust was the primary building material for the meteorites and terrestrial planets. To make this case, the characteristics of presolar dust are discussed and the material in the sun's parent molecular cloud is divided into eight reservoirs. Then the meteorites most likely to preserve their original constituents are identified, and it is shown that dust from several presolar material reservoirs is present in the primitive chondrites. Components that may have formed directly from presolar dust are also identified. Presolar dust and objects made from processed dust make up the vast majority of the material in primitive chondrites. Since there is no obvious reason to believe that other meteorites formed from fundamentally different material than did the primitive chondrites, it is reasonable to conclude that presolar dust, thermally processed but not evaporated and recondensed, was the parent material for the meteorites.In the second part of the paper, various processes that could have affected the presolar dust are identified. It is then shown that: (1) the chemical and oxygen isotopic variations between meteorite classes; (2) the formation of chondrules; and (3) accretion of chondrites and parent body metamorphism are consistent with relatively simple models that use presolar dust as the starting material. These models are presented, not as detailed solutions to the problems, but to exemplify a way of looking at the solar system that may lead to significant advances in our understanding.  相似文献

Scattered ground‐roll attenuation using model‐driven interferometry          下载免费PDF全文

Phil Bilsby  Lee West  Ed Kragh  John Quigley 《Geophysical Prospecting》2015,63(1):116-132

Scattered ground roll is a type of noise observed in land seismic data that can be particularly difficult to suppress. Typically, this type of noise cannot be removed using conventional velocity‐based filters. In this paper, we discuss a model‐driven form of seismic interferometry that allows suppression of scattered ground‐roll noise in land seismic data. The conventional cross‐correlate and stack interferometry approach results in scattered noise estimates between two receiver locations (i.e. as if one of the receivers had been replaced by a source). For noise suppression, this requires that each source we wish to attenuate the noise from is co‐located with a receiver. The model‐driven form differs, as the use of a simple model in place of one of the inputs for interferometry allows the scattered noise estimate to be made between a source and a receiver. This allows the method to be more flexible, as co‐location of sources and receivers is not required, and the method can be applied to data sets with a variety of different acquisition geometries. A simple plane‐wave model is used, allowing the method to remain relatively data driven, with weighting factors for the plane waves determined using a least‐squares solution. Using a number of both synthetic and real two‐dimensional (2D) and three‐dimensional (3D) land seismic data sets, we show that this model‐driven approach provides effective results, allowing suppression of scattered ground‐roll noise without having an adverse effect on the underlying signal.  相似文献
