Book Description
The investigation of key mineral phases such as zircon, apatite, titanite, rutile, monazite, xenotime, allanite, baddeleyite and garnet, explored in this book, has provided breakthroughs in our understanding of continental crust composition and evolution, as well as the timing, conditions, petrogenetic and geodynamic processes related to its growth and reworking. Therefore, the continuing development of analytical techniques, improvement of tools, data handling, processing, and interpretation allow us to extract and better understand these complex geological processes. This special publication aims at showcasing contributions reviewing the tools and applications of these key minerals, recent technique developments, and new applications using focused case studies investigating igneous, metamorphic and/or detrital rocks that help us put together the continental crust evolution puzzle. This volume highlights the progress made in studies using these key minerals and their future potential.

Book Description
This book presents the first overview of the composition and structure of the Earth’s lower mantle. The first part focuses on the study of lower-mantle minerals, identified as inclusions in diamonds from different regions of the world. Three associations are established among the lower-mantle minerals: ultramafic, mafic, and carbonatic. The carbonatic association is of particular interest because it characterizes the media of natural diamond formation. In turn, the second part analyzes the structure of the lower mantle, revealing its heterogeneous composition. It is based on the results of experiments demonstrating phase transitions in lower-mantle minerals, and on seismological data. Deep-seated earthquakes point to the presence within the lower mantle of numerous seismic boundaries caused by mineral structure transitions. In closing, the last part of the book compares observed data with experimental data, highlighting several discrepancies that indicate Earth may have a more complex planetary history than previously assumed, and examining its primarily non-chondritic composition.

Abstract: The first eon of the Earth, Hadean, is no doubt critical for the evolution of Earth towards a habitable planet and the origin of life. However, there is almost no petrologic record preserved for this piece of history because of the long-term geological reworking. In this study, batch experiments simulating the interaction between the early Earth's ultramafic crust and H2O-CO2 atmosphere were performed in order to gain some new insights into the direct interaction and its influence on the evolution of mineral, atmosphere, ocean and the prebiotic chemistry on the early Earth. Electron microscopic observations (including SEM and TEM) show that the secondary minerals produced in the experiments mainly include phyllosilicates, carbonates and Fe-oxide. Phyllosilicates which are essential for biomonomer synthesis can be found in each of our experiments. Different rock-water-H2O systems result in different clay minerals with varied crystal habits. Carbonates can be found in experiments carried out at temperature below 400 C. With the experimental temperature decrease from 400 C to 200 C, the formed carbonates change from calcite, dolomite and magnesite accordingly. Energy dispersive spectroscopy reveals the incorporation of iron in all kinds of carbonates. Hexagonal magnetite nanoplates are observed in komatiite-H2O-CO2 experiment carried out at 450 C. The mineralogical compositions imply that the interaction between the early Earth's ultramafic crust and H2O-CO2 atmosphere were able to produce clay minerals, carbonates and oxides on the rocky planets such as Earth, which was corroborated by the recent discovery of layered clay minerals and carbonates assemblages on Mars. More importantly, these secondary minerals are effective in catalyzing the inorganic molecular to biomolecules that are essential in prebiotic chemical evolution. The GC measurement of the gaseous phases trapped in the capsule after experiments show that abiogenetic methane, ethane and propane as well as hydrogen were detected in most our experiments. The relative concentrations of these gases are higher in high temperature experiments, which indicate high productivity of CH4 and H2 during the interaction between the early Earth's ultramafic crust and H2O-CO2 atmosphere. The abiotic formation and accumulation of H2, methane, and short hydrocarbon would not only provide material basis for the chemical evolution towards life but also play essential roles in preventing the surface of the Earth from freezing in the Hadean eon while the Earth was suffering from extensive precipitation of atmospheric CO2 and the faint young sun. Generally, the earliest interaction between the Earth's ultramafic crust and H2O-CO2 atmosphere could have changed the physicochemical condition of the Earth's surface that favored the prebiotic chemical evolution towards life.

Book Description
Volume 57 of Reviews in Mineralogy and Geochemistry highlights the present knowledge on micro- and mesoporous mineral phases, with focus on their crystal-chemical aspects, occurrence and porous activity in nature and experiments. As zeolites are the matter of numerous ad hoc meetings and books - including two volumes in this series - they do not specifically appear in the present volume. The phases of the sodalite and cancrinite-davyne groups, which mineralogists consider distinct from zeolites, are instead considered (in the order, chapter 7 by W. Depmeier and part of chapter 8 by E. Bonaccorsi and S. Merlino, respectively).

Book Description
While the chemical aspects of igneous petrology have dominated research for many years, the physical processes associated with the generation, transport, and crystallization of magma have been somewhat neglected. Here a group of distinguished scientists, whose current research embraces both chemical and physical aspects of the field, illustrates these new directions in igneous petrology. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
