Microbial systems in extreme environments and in the deep biosphere may be analogous to potential life on other planetary bodies and hence may be used to investigate the possibilities of extraterrestrial life.

One of today¿s major geoscientific controversies centres on the origin of the Archean granite¿greenstone terranes. Is the geology of these scattered remnants of our planet¿s early crust consistent with the theory that modern-style plate-tectonic processes operated from the early Archean, or does it indicate that tectonic and magmatic processes were different in the Archean? Earth has clearly evolved since its initial formation, so at what stage did its processes of crustal growth first resemble those of today? The logical place to seek answers to these intriguing and important questions is within the best-preserved early Archean crust. The Pilbara region of northwest Australia is internationally famous for its abundant and exceptionally well-preserved fossil evidence of early life. However, until recently the area has received much less recognition for the key evidence it provides on early Archean crustal evolution. This book presents and interprets this evidence through a new stage-by-stage account of the development of the Pilbaräs geological record between 3.53 and 2.63 Ga. The Archean Pilbara crust represents one fragment of Earth¿s oldest known supercontinent Vaalbara, which also included the Kaapvaal Craton of southern Africa. Recognition of Vaalbara expands the background database for both these areas, allowing us to more fully understand each of them.

This book describes the mineralization process of barite-fluorite deposits in southeastern Sichuan, Yangtze Block, China. Mainly through systematic field geological surveys and detailed indoor research work, the typical barite-fluorite deposits in this area were analyzed using a variety of analysis methods such as single fluid inclusion LA-ICP-MS composition analysis, trace rare earth element analysis, H-O-S-Sr isotope analysis, F element content analysis, and Sm-Nd geochronological analysis. By in-depth analysis of the ore-forming environment, mineralization process and geological characteristics of barite-fluorite deposits, the following were determined: (1) the source of ore-forming fluids of barite-fluorite deposits and (2) the migration, concentration, enrichment, and evolution of ore-forming sources, exploring the formation mechanism of barite-fluorite deposits. Summarizing the mineralization regularity of the deposit in this area of China provides a new insight and basis for the study of similar types of deposits in the world.

This book is the first systematic treatise of available data and view-points obtained from geological and geochemical studies of the Mo deposits in Qinling Orogen, China. It hosts 49 Mo deposits formed in seven mineralization events since 1850 Ma, with all the world-class deposits being formed during 160-105 Ma, coeval with collisional orogeny.

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.

This book describes for the first time the complexity of the Northeastern Transbaikalia province of Russia.

This book furnishes detailed information about Turkey's existing mineral resources, besides providing concepts and ideas which may help the search for potential mineral resources in the future.

This book presents an integrated approach to the study of the evolution of the Archean lithosphere, biosphere and atmosphere, and as such it is a unique contribution to our understanding of the early Earth and life.

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.

This book documents the geological, geophysical, geochemical and paleontological features of modern accretionay prisms and trenches in the northwestern Pacific Ocean, based on 10 years of submersible dive cruises, ODP drilling projects and geophysical surveys.

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 Permian - Triassic and Paleogene volcano-plutonic and plutonic associations are two important geological events in the evolutionary history of Southeast Asia, including the 260 - 250 Ma Emeishan mantle plume and Indian-Eurasia collision at 60 - 55 M. The volume includes 9 chapters, divided into 3 parts.
