THE MINERALOGICAL MAGAZINE AND JOURNAL OF THE MINERALOGICAL SOCIETY. 1~o. 40. OCTOBER 1889. Vol. VIII. On the Meteorites which have been found iu the Desert of Atacama and its neighbourhood. By L. FLETCHER, M.A., F.R.S., Keeper of Minerals in the British Museum. (With a Map of the District, Plate X.) [Read March 12th and May 7th, ]889.J 1. THE immediate object of the present paper is to place on record J- the history and characters of several Atacama meteorites of which no description has yet been published; but incidentally it is con- venient at the same time to consider the relationship of these masses to others from the same region, which either have been already described, or at least are stated to be preserved in one or more of the known Meteo. rite-Collections. 2. The term " Desert of Atacama " is generally applied to that part of western South America which lies between the towns of Copiapo and Cobija, about 330 miles distant from each other, and which extends island as far as the Indian hamlet of Antofagasta, about 180 miles from 224 L.

A critical examination of the descriptive literature, and a compari- son of the manuscript and printed meteorite-lists, which have been placed at my service, lead to the conclusion that all the meteoritic frag- ments from Atacama now preserved in the known Collections belong to one or other of at most thirteen meteorites, which, for reasons given below, are referred to in this paper under the following names :-- 1. -

Geological Survey Research 1961 Synopsis of Geologic and Hydrologic Results
Geological Survey Research 1961 Synopsis of Geologic and Hydrologic Results GEOLOGICAL SURVEY PROFESSIONAL PAPER 424-A Geological Survey Research 1961 THOMAS B. NOLAN, Director GEOLOGICAL SURVEY PROFESSIONAL PAPER 424 A synopsis ofgeologic and hydrologic results, accompanied by short papers in the geologic and hydrologic sciences. Published separately as chapters A, B, C, and D UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1961 FOEEWOED The Geological Survey is engaged in many different kinds of investigations in the fields of geology and hydrology. These investigations may be grouped into several broad, inter related categories as follows: (a) Economic geology, including engineering geology (b) Eegional geologic mapping, including detailed mapping and stratigraphic studies (c) Eesource and topical studies (d) Ground-water studies (e) Surface-water studies (f) Quality-of-water studies (g) Field and laboratory research on geologic and hydrologic processes and principles. The Geological Survey also carries on investigations in its fields of competence for other Fed eral agencies that do not have the required specialized staffs or scientific facilities. Nearly all the Geological Survey's activities yield new data and principles of value in the development or application of the geologic and hydrologic sciences. The purpose of this report, which consists of 4 chapters, is to present as promptly as possible findings that have come to the fore during the fiscal year 1961 the 12 months ending June 30, 1961. The present volume, chapter A, is a synopsis of the highlights of recent findings of scientific and economic interest. Some of these findings have been published or placed on open file during the year; some are presented in chapters B, C, and D ; still others have not been pub lished previously. -
The Tennessee Meteorite Impact Sites and Changing Perspectives on Impact Cratering
UNIVERSITY OF SOUTHERN QUEENSLAND THE TENNESSEE METEORITE IMPACT SITES AND CHANGING PERSPECTIVES ON IMPACT CRATERING A dissertation submitted by Janaruth Harling Ford B.A. Cum Laude (Vanderbilt University), M. Astron. (University of Western Sydney) For the award of Doctor of Philosophy 2015 ABSTRACT Terrestrial impact structures offer astronomers and geologists opportunities to study the impact cratering process. Tennessee has four structures of interest. Information gained over the last century and a half concerning these sites is scattered throughout astronomical, geological and other specialized scientific journals, books, and literature, some of which are elusive. Gathering and compiling this widely- spread information into one historical document benefits the scientific community in general. The Wells Creek Structure is a proven impact site, and has been referred to as the ‘syntype’ cryptoexplosion structure for the United State. It was the first impact structure in the United States in which shatter cones were identified and was probably the subject of the first detailed geological report on a cryptoexplosive structure in the United States. The Wells Creek Structure displays bilateral symmetry, and three smaller ‘craters’ lie to the north of the main Wells Creek structure along its axis of symmetry. The question remains as to whether or not these structures have a common origin with the Wells Creek structure. The Flynn Creek Structure, another proven impact site, was first mentioned as a site of disturbance in Safford’s 1869 report on the geology of Tennessee. It has been noted as the terrestrial feature that bears the closest resemblance to a typical lunar crater, even though it is the probable result of a shallow marine impact. -

Elastic Properties of Iron Meteorites. Nikolay Dyaur1, Robert R. Stewart1, and Martin Cassidy1, 1University of Houston, Science
51st Lunar and Planetary Science Conference (2020) 3063.pdf Elastic properties of iron meteorites. Nikolay Dyaur1, Robert R. Stewart1, and Martin Cassidy1, 1University of Houston, Science and Research Building 1, 3507 Cullen Boulevard, room 312, Houston, TX 77204, [email protected] Introduction: We investigate the elastic properties of a ture, in the iron meteorites indicates directionality in variety of iron meteorites using ultrasonic (0.5 MHz to 5 physical properties. So, we explored the possibility of MHz) laboratory measurements. Our meteorite samples elastic anisotropy. First, we estimated Vp- and Vs- include Campo de Cielo, Canyon Diablo, Gibeon, and anisotropy from the measured maximum and minimum Nantan. The densities of the meteorites range from 7.15 velocity for each sample. g/cc to 7.85 g/cc. P-wave velocities are from 5.58 km/s to 7.85 km/s, and S-wave velocities are from 2.61 km/s to 3.37 km/s. There is a direct relationship between P-wave velocity and density (approximately quadratic). We find evidence of anisotropy and S-wave splitting in the Gibe- on sample. These measurements may help inform studies related to planetary core properties, asteroid mining, and Earth protection. Iron meteorites are composed of Fe-Ni mixes with Fe content around 90%. The principal minerals are kamacite and taenite with some inclusions mainly repre- sented by troilite, graphite, diamond, gold, quartz, and some others. Iron meteorites are divided into groups based on their structure linked to Ni content: Hexahe- drites (4-6% of Ni), Octahedrites (6-14% of Ni) and Nickel-rich ataxites (>12% of Ni) [1].
