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 permutation of basic atoms—nitrogen, hydrogen, oxygen, carbon and phosphorus-into the biomolecules DNA and RNA, subsequently evolved in cells and brains, defining the origin of life and intelligence, remains unexplained.

With the advent of global warming and the nuclear arms race, humans are rapidly approaching a moment of truth. Technologically supreme, they manifest their dreams and nightmares in the real world through science, art, adventures and brutal wars, a paradox symbolized by a candle lighting the dark yet burning away to extinction, as discussed in this book. As these lines are being written, fires are burning on several continents, the Earth’s ice sheets are melting and the oceans are rising, threatening to flood the planet’s coastal zones and river valleys, where civilization arose and humans live and grow food.With the exception of birds like hawks, black kites and fire raptors, humans are the only life form utilizing fire, creating developments they can hardly control. For more than a million years, gathered around campfires during the long nights, mesmerized by the flickering life-like dance of the flames, prehistoric humans acquired imagination, a yearningfor omnipotence, premonitions of death, cravings for immortality and conceiving the supernatural. Humans live in realms of perceptions, dreams, myths and legends, in denial of critical facts, waking up for a brief moment to witness a world that is as beautiful as it is cruel. Existentialist philosophy offers a way of coping with the unthinkable. Looking into the future produces fear, an instinctive response that can obsess the human mind and create a conflict between the intuitive reptilian brain and the growing neocortex, with dire consequences. As contrasted with Stapledon’s Last and first Man, where an advanced human species mourns the fate of the Earth, Homo sapiens continues to transfer every extractable molecule of carbon from the Earth to the atmosphere, the lungs of the biosphere, ensuring the demise of the planetary life support system.”

This book presents a history which is nearing its nadir, where a species of warlike primates is destroying the delicate web of life perceived by Charles Darwin in The Origin of Species, committing a war against nature and the fastest mass extinction in the history of nature, with global temperatures incinerating the biosphere by several degrees Celsius, within a lifetime. Despite of this knowledge, Homo “sapiens” is proceeding to transfer every accessible molecule of carbon from the Earth crust to the atmosphere and hydrosphere, an auto-da-fe ensues of the terrestrial biosphere. As amplifying feedbacks to global warming—including fires, methane release, ice melt, and warming oceans—are intensifying, at a pace exceeding any recorded in the geological past, societies are pouring their remaining resources into wars. These include likely nuclear wars triggered by arsenals many thousands of missiles strong, posing an equal threat to human existence and that of many other species. Humans, having mastered fire, which allowed them to survive the extreme ice ages, have emerged in the current interglacial as major civilizations coupled with major bloodsheds, called “war”, engulfing multitudes of innocent yet betrayed humans. Long suffering from illusions of omnipotence and omniscience, paranoid fears, a warlike mindset, aggression toward the animals and disrespect of females, coupled with artistic excellence and technical brilliance, humans have become victims to a tragic conflict between the mind and the heart, with fatal consequences.

This book is based on studies during 1964-2007 of Archaean terrains in Australia and to a lesser extent in South Africa and India, as well as on visits to Archaean terrains in Canada, the US and China, as well as petrological and geochemical studies of igneous and sedimentary rock suites from a range of terrains.

The book outlines principal milestones in the evolution of the atmosphere, oceans and biosphere during the last 4 million years in relation with the evolution from primates to the genus Homo – which uniquely mastered the ignition and transfer of fire. The advent of land plants since about 420 million years ago ensued in flammable carbon-rich biosphere interfaced with an oxygen-rich atmosphere. Born on a flammable Earth surface, under increasingly unstable climates descending from the warmer Pliocene into the deepest ice ages of the Pleistocene, human survival depended on both—biological adaptations and cultural evolution, mastering fire as a necessity. This allowed the genus to increase entropy in nature by orders of magnitude. Gathered around camp fires during long nights for hundreds of thousandth of years, captivated by the flickering life-like dance of the flames, humans developed imagination, insights, cravings, fears, premonitions of death and thereby aspiration for immortality, omniscience, omnipotence and the concept of god. Inherent in pantheism was the reverence of the Earth, its rocks and its living creatures, contrasted by the subsequent rise of monotheistic sky-god creeds which regard Earth as but a corridor to heaven. Once the climate stabilized in the early Holocene, since about ~7000 years-ago production of excess food by Neolithic civilization along the Great River Valleys has allowed human imagination and dreams to express themselves through the construction of monuments to immortality. Further to burning large part of the forests, the discovery of combustion and exhumation of carbon from the Earth’s hundreds of millions of years-old fossil biospheres set the stage for an anthropogenic oxidation event, affecting an abrupt shift in state of the atmosphere-ocean-cryosphere system. The consequent ongoing extinction equals the past five great mass extinctions of species—constituting a geological event horizon in the history of planetEarth.

Archaean terrains contain a wealth of structural, stratigraphic, textural, mineralogical, geochemical and isotopic features allowing insights into the nature of the early Earth. This book is based on studies during 1964-2007 of Archaean terrains in Australia and to a lesser extent in South Africa and India, as well as on visits to Archaean terrains in Canada, the US and China, as well as petrological and geochemical studies of igneous and sedimentary rock suites from a range of terrains. The book will include a range of photographic and microscopic images, geological sketch maps and diagrams illustrating the lessons derived from field and the laboratory. Also other Archaean terrains are being reviewed.The book is intended for Earth scientists as well as broader intelligent readership.

When in 1981 Louis and Walter Alvarez, the father and son team, unearthed a tell-tale Iridium-rich sedimentary horizon at the 65 million years-old Cretaceous-Tertiary boundary at Gubbio, Italy, their find heralded a paradigm shift in the study of terrestrial evolution.  Since the 1980s the discovery and study of asteroid impact ejecta in the oldest well-preserved terrains of Western Australia and South Africa, by Don Lowe, Gary Byerly, Bruce Simonson, Scott Hassler, the author and others, and the documentation of new exposed and buried impact structures in several continents, have led to a resurgence of the idea of the catastrophism theory of Cuvier, previously largely supplanted by the uniformitarian theory of Hutton and Lyell. Several mass extinction of species events are known to have occurred in temporal proximity to large asteroid impacts, global volcanic eruptions and continental splitting. Likely links are observed between asteroid clusters and the 580 Ma acritarch radiation, end-Devonian extinction, end-Triassic extinction and end-Jurassic extinction. New discoveries of ~3.5 – 3.2 Ga-old impact fallout units in South Africa have led Don Lowe and Gary Byerly to propose a protracted prolongation of the Late Heavy Bombardment (~3.95-3.85 Ga) in the Earth-Moon system. Given the difficulty in identifying asteroid impact ejecta units and buried impact structures, it is likely new discoveries of impact signatures are in store, which would further profoundly alter models of terrestrial evolution..
