Download or read book The Moon s Largest Craters and Basins written by Charles J. Byrne and published by Springer. This book was released on 2015-11-19 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This most recent book from lunar expert Charles J. Byrne combines the latest comprehensive imagery, topography and gravity data from all three recent Moon missions, Kaguya, Lunar Reconnaissance Orbiter and GRAIL. These major polar-orbit surveys are presented here in compact form for the convenience of amateur and practical astronomers concerned with the Moon. Chosen from the Near and Far Side's large craters and basins over 200 km in diameter, each of the 71 highlighted features is depicted with a two-page presentation of the data that includes false color topographic maps next to the mission images. Additionally, the features are presented in the estimated chronological sequence of their creation, based on a consideration of stratigraphy (overlapping layers from neighboring features) and the relative degradation of surface features. Using this sequence as a way to convey the relative ages of lunar features, the author presents various theories concerning the Moon’s impact and thermal history e.g. the available evidence allows for constraints to be placed on the duration of the Late Heavy Bombardment period. The relationships between impact dynamics and variations in the gravity field of the Moon are also discussed. The new mission data makes possible this renewed conjecture about the history and evolution of the Moon, which is presented here with much worthwhile information for amateurs and professionals alike.

Download or read book Impact Craters of Earth written by Thomas Wm. Hamilton and published by Strategic Book Publishing & Rights Agency. This book was released on 2014-08-27 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Craters have been found on planets and moons throughout the solar system, caused when asteroids or meteors have collided with them. Our Earth has not escaped these impacts, and nearly 200 craters are known on Earth today. Some are easily visited, others are in locations few would ever want to get near. This book details all the known terrestrial impact craters, telling their age, size, and other details, as well as highlighting those easily visited. One has an annual “Craterfest” to attract tourists, while it is possible to swim in lakes that have filled others.

Download or read book The Moon s Near Side Megabasin and Far Side Bulge written by Charles Byrne and published by Springer Science & Business Media. This book was released on 2014-02-01 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Luna and Lunar Orbiter photographed the far side of the Moon, the mysterious dichotomy between the face of the Moon as we see it from Earth and the side of the Moon that is hidden has puzzled lunar scientists. As we learned more from the Apollo sample return missions and later robotic satellites, the puzzle literally deepened, showing asymmetry of the crust and mantle, all the way to the core of the Moon. This book summarizes the author’s successful search for an ancient impact feature, the Near Side Megabasin of the Moon and the extensions to impact theory needed to find it. The implications of this ancient event are developed to answer many of the questions about the history of the Moon.

Download or read book Modeling and Mapping of the Structural Deformation of Large Impact Craters on the Moon and Mercury written by Jeffrey Balcerski and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large craters and impact basins that are present on nearly every solid body in the solar system are remnants of a cataclysmic process that excavated, melted, vaporized, and ejected tremendous amounts of material from the surface of the planets. The results of this process of energy release and topographic disruption can be used to derive information about the deep geologic past of the planets. On Mercury, the topography of the melted sheet which forms interior floors of craters> 12 km in diameter, is well preserved and can be measured using the altimetric data from the MESSENGER orbital mission. I use these measurements to place chronologic constraints on the onset and duration of some of Mercury's large-scale topographic features. On the Moon, the events that formed impact craters measuring over 120 km in diameter were capable of disrupting the crust-mantle boundary. Many of those perturbations have persisted through the billions of years since their formation. The processes that preserve this remarkable topography and the way in which it deforms over time, are poorly constrained due to the lack of observation of geologically recent basin formation events. However, constraints on these processes can be determined using models governed by high resolution gravity and topography data gathered from recent orbital missions to the Moon, as well as data produced by laboratory rheology experiments. I measure and catalog the morphologic characteristics of the lunar basins and develop numerical finite element structural models in order to evaluate hypotheses about the formation of these features and provide new insight into the structural evolution of the Moon's shallow interior.

Download or read book Structure of the Moon s Surface written by Gilbert Fielder and published by Elsevier. This book was released on 2013-09-03 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structure of the Moon's Surface aims to assemble and marshal relevant matter, and to produce a largely unprejudiced text which brings lunar studies up to date and stresses the importance of certain features of the Moon which have frequently been disregarded in the past, largely because of lack of knowledge about them. The book contains 14 chapters organized into two parts. Part I reviews and summarizes important physical problems. These include the liberations of the moon; height determinations of points of the moon's surface; the figure of the moon; and the moon's temperature and atmosphere. Part II discusses relatively new facts and ideas, which have been insufficiently emphasized in the past. Topics covered include ray systems; rilles, faults, and wrinkle ridges; and crater distribution and frequency. It is hoped that this book will be of use both to the professional scientist and to the amateur astronomer.

Download or read book On the Distribution of Large Lunar Craters written by Luciano Bruno Ronca and published by . This book was released on 1968 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The size distribution and location of all the craters of classes 1, 2, and 3 larger than 25 km in diameter on the front face of the moon were studied. The diameter distribution of the craters follows approximately the distribution that would be expected from meteoritic impact. Lateral variations in cratering over the lunar surface were determined by dividing the lunar disk into 172 equiareal zones, each of approximately 76,900 sq km. The number of craters, their average diameter and the sum of their diameters were measured in each zone. When these parameters are contoured on the lunar surface, they outline not only the maria but also areas on the terrae otherwise indistinguishable. On the terrae the amount of cratering is not random; highly cratered areas occur clustered together with a correlation coefficient of 0.776. Lateral variations in size distribution were studied by dividing the front face of the moon into 9 zones, each of which has at least 60 large craters and follows approximately the physiography. The main variations are due to the maria and terrae distribution; however, differences in the terrae are also indicated. It is concluded that meteoritic impact cannot offer all the answers to the origin of lunar craters. Either the craters are predominantly volcanic, or some endogenic control on the size of an impact crater exists. (Author).

Download or read book Impact Craters in South America written by Rogelio Daniel Acevedo and published by Springer. This book was released on 2015-04-25 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete and updated catalogue of impact craters and structures in South America from 2014 is presented here. Approximately eighty proven, suspected and disproven structures have been identified by several sources in this continent. All the impact sites of this large continent have been exhaustively reviewed: the proved ones, the possible ones and some very doubtful. Many sites remain without a clear geological "in situ" confirmation and some of them could be even rejected. Argentina and Brazil are leading the list containing almost everything detected. In Bolivia, Chile, Colombia, Guyana, Paraguay, Perú, Uruguay and Venezuela only a few were observed. Only Ecuador is waiting for new discoveries. So far, the largest well stated impact site is still the Araguainha structure in Brazil with its 40 kilometers in diameter. However, two possible impact structures are larger than Araguainha: Malvinas, (with 250 kilometers in diameter) and Vichada in Colombia, (50 kilometers). This study also reports the existence of some Tertiary-Quaternary glassy impactite layers: the "escorias" and "tierras cocidas" of the pampas in Argentina.

Download or read book The Geologic History of the Moon U S Geological Survey Professional Paper 1348 written by U S Department of the Interior and published by . This book was released on 2023-11-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than two decades of study have established the major features of lunar geologic style and history. The most numerous and significant landforms belong to a size-morphology series of simple craters, complex craters, and ringed basins that were formed by impacts. Each crater and basin is the source of primary ejecta and secondary craters that, collectively, cover the entire terra. The largest impacts thinned, weakened, and redistributed feldspathic terracrustal material averaging about 75 km in thickness. Relatively small volumes of basalt, generated by partial remelting of mantle material, were erupted through the thin subbasin and subcrater crust to form the maria that cover 16 percent of the lunar surface. Tectonism has modified the various stratigraphic deposits relatively little; most structures are confined to basins and large craters. This general geologic style, basically simple though complex in detail, has persisted longer than 4 aeons (1 aeon = 109 yr). Impacts began to leave a visible record about 4.2 aeons ago, after the crust and mantle had differentiated and the crust had solidified. At least 30 basins and 100 times that many craters larger than 30 km in diameter were formed before a massive impact created the Nectaris basin about 3.92 aeons ago. Impacts continued during the ensuing Nectarian Period at a lesser rate, whereas volcanism left more traces than during pre-Nectarian time. The latest basin-forming impacts created the giant and still-conspicuous Imbrium and Orientale basins during the Early Imbrian Epoch, between 3.85 and 3.80 aeons ago. The rate of crater-forming impacts continued to decline during the Imbrian Period. Beginning in the Late Imbrian Epoch, mare-basalt flows remained exposed because they were no longer obscured by many large impacts. The Eratosthenian Period (3.2-1.1 aeons ago) and the Copernican Period (1.1 aeons ago to present) were times of lesser volcanism and a still lower, probably constant impact rate. Copernican impacts created craters whose surfaces have remained brighter and topographically crisper than those of the more ancient lunar features.

Download or read book Chesapeake Invader written by C. Wylie Poag and published by Princeton University Press. This book was released on 2017-03-14 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirty-five million years ago, a meteorite three miles wide and moving sixty times faster than a bullet slammed into the sea bed near what is now Chesapeake Bay. The impact, more powerful than the combined explosion of every nuclear bomb on Earth, blasted out a crater fifty miles wide and one mile deep. Shock waves radiated through the Earth for thousands of miles, shaking the foundations of the Appalachians, as gigantic waves and winds of white-hot debris transformed the eastern seaboard into a lifeless wasteland. Chesapeake Invader is the story of this cataclysm, told by the man who discovered it happened. Wylie Poag, a senior scientist with the U.S. Geological Survey, explains when and why the catastrophe occurred, what destruction it caused, how scientists unearthed evidence of the impact, and how the meteorite's effects are felt even today. Poag begins by reviewing how scientists in the decades after World War II uncovered a series of seemingly inexplicable geological features along the Virginia coast. As he worked to interpret one of these puzzling findings in the 1980s in his own field of paleontology, Poag began to suspect that the underlying explanation was the impact of a giant meteorite. He guides us along the path that he and dozens of colleagues subsequently followed as--in true scientific tradition--they combined seemingly outrageous hypotheses, painstaking research, and equal parts good and bad luck as they worked toward the discovery of what turned out to be the largest impact crater in the U.S. We join Poag in the lab, on deep-sea drilling ships, on the road for clues in Virginia, and in heated debates about his findings. He introduces us in clear, accessible language to the science behind meteorite impacts, to life and death on Earth thirty-five million years ago, and to the ways in which the meteorite shaped the Chesapeake Bay area by, for example, determining the Bay's very location and creating the notoriously briny groundwater underneath Virginia. This is a compelling work of geological detective work and a paean to the joys and satisfactions of a life in science. Originally published in 1999.
