On Earth, catastrophic impact of an asteroid or comet with truly global consequences has not happened during our written history, and the threat seems very small. Giant scars on our planet’s surface are relics of an impact history stretching back more than 2 billion years, and there is no assurance it cannot happen again. In Australia there are 36 structures ranging from tens of metres to tens of kilometres in diameter, and recognised to varying degrees of certainty as having been formed by giant meteorite impact. In clear and concise language this book begins with ancient beliefs and myths about craters and then explains how they are actually formed and provides details of their structure. Using the record in the rocks, the authors also assess the likelihood of future impacts and their possible effects.

In 1931, the cluster of craters at Henbury Cattle Station south of Alice Springs in Central Australia was one of the first places on Earth where a group of impact structures could definitely be linked to the fall of iron meteorites. It was also the first place where radial rays and loops of ejected rock material, comparable to those seen around craters on the Moon, were observed. As such it was one of the primary observation sites associated with the science of meteoritics in its infancy. In this work the authors present previously unpublished documents covering early research at the Henbury site, provide an extended data set on the distribution of meteoritic material at Henbury craters, and compare recent discoveries on the mechanics of hypervelocity impacts with evidence collected over 80 years of research at the Henbury meteorite craters. In their conclusion, the authors suggest a new hypothesis for the fragmentation and incident direction of the crater-forming bolide, on the basis of a more complete set of data compared with previous models.

This book presents a comprehensive overview of Australian impact structures and related mineralization, including a discussion of the significance of many of these structures for crustal evolution. The book focuses in particular on Archaean impact ejecta/fallout units in the Pilbara Craton of Western Australia, large exposed and buried impact structures, and on the geophysical evidence for possible to probable impact structures. Thanks to their long-term geological stability, Precambrian and younger terrains in the Australian continent contain 38 confirmed impact structures and 43 ring and dome structures, many of which constitute possible to probable asteroid impact structures. The impact structures have been the subject of more than half a century of studies and range from several tens of meter-large craters to buried structures larger than 100 km in diameter. Discoveries of impact fallout units in the Pilbara Craton have defined the Pilbara as one of the two best documented terrains where Archaean impact ejecta/fallout deposits are identified, the other terrain being the Kaapvaal Craton in southern Africa. A synthesis of evidence from both cratons indicates periods of large asteroid bombardments during ~3.47 – 2.48 billion years-ago, including peak bombardment about 3.25—3.22 billion years-ago. The latter period coincides with an abrupt transformation of an early Archaean granite-greenstone crust to mid to late Archaean semi-continental crustal regimes, underpinning the significance of heavy asteroid impact events for crustal evolution. Apart from proven impact structures, Australian terrains display a range of circular features, including morphological and drainage rings, circular lakes, volcanic craters, tectonic domes, oval granite bodies, mafic igneous plugs, salt diapirs, and magnetic, gravity and seismic anomalies, many of which are of a likely impact origin. Thermal and hydrothermal processes associated with impact cratering bear important consequences for the formation of mineral deposits, such as Ni at Sudbury, Pb-Zn at Siljan and Kentland. Impact structures may also provide sites for the accumulation of hydrocarbons, whereas in some instances fracturing associated with impact structures allows outward migration of oil and gas.

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.
