Описание: It is probably true to say that the findings from Oldoinyo Lengai have dominated our ideas about carbonatites, in spite of the fact that the alkali- rich, natrocarbonatitic lavas of Oldoinyo Lengai are markedly different from other carbonatites.

Описание: Rock metamorphism is a geological process that changes the mineralogical and chemical composition, as well as the structure of rocks. Metamorphism is typically associated with elevated temperature and pressure, thus it affects rocks within the earths crust and mantle. Metamorphic rocks are made by either heating up or squashing the earths crust. They are often found in mountainous regions. A metamorphic rock is a result of a transformation of a pre-existing rock. The most typical metamorphism transforms sedimentary rocks to metamorphic rocks by addition of heat during mountain building or by a large volume of magma in the crust. The original rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes. One example is slate. Slate was originally a black mud laid down on the bottom of the sea or lake. Fossils Andreas can sometimes be found in it but they are often squashed. Due to the action of plate tectonics, compression, stress and shearing forces over long periods of time, rocks can be essentially warped and deformed, causing them to be compacted into a smaller volume of space. As a consequence, metamorphic rocks are always more dense than their original material, and also much less susceptible to erosional breakdown. As the Earths plates move over geologic time, a plate containing igneous or sedimentary rock may become subducted under another plate. The sheer weight of the material above it can cause the rock to undergo metamorphism. This book discusses the most common metamorphic rock types, structure and graphical representation of their mineral assemblages. It defines basic principles of metamorphism and metamorphic processes.

Описание:
This book describes the nature and origin of the Macraes gold deposit. It also documents the key features of this spectacular deposit for a wide range of professionals in the resource geology community. This world-class gold deposit has been a spectacular geological and economic success story, as it has developed from a small historical gold mine in discontinuous quartz veins measuring only meters to a large-scale mine in deposits spreading over kilometres in extensive disseminated gold-bearing rock.

Описание: This book systematically describes and illustrates the major ore deposit types, and links them to their settings in the crust and the geological factors behind their formation. It provides a balance of practical information and the background science for advanced undergraduate and graduate students. Includes end-of-chapter questions and online visual resources.
Описание: Minerals respond texturally and compositionally to changing magmatic environments and preserve a wealth of information regarding magmatic processes and compositions in their crystal-growth stratigraphy. This book reports the detailed petrography and in-situ geochemistry of the clinopyroxene phenocrysts of the mafic dykes in the Jiaodong Peninsula, southeastern North China Craton, including in-situ determinations of major elements, trace elements, Sr isotopic compositions, and H2O contents with further constraints on the petrogenesis and geodynamics of the mafic dykes. Systematic analyses of mineralogical, major, and trace elements, Sr–Nd isotopes, and in-situ S isotopes on the pyrite of the main gold-bearing mineral assemblages and visible gold were conducted, aiming to explore the source of ore-forming materials and the process of Au element migration and deposition. The geodynamic setting of mineralization in the studied region is also summarized.

Описание: The first edition of this book was published in 1965 and its French translation in 1966. The revised second edition followed in 1967 and its Russian translation became available in 1969. Since then, many new petrographic observations and experimental data elucidat- ing reactions in metamorphic rocks have made a new approach in the study of metamorphic transformation desirable and possible. It is felt that this new approach, attempted in this book, leads to a better unders- tanding of rock metamorphism. The concept of metamorphic facies and subfacies considers asso- ciations of mineral assemblages from diverse bulk compositions as characteristic of a certain pressure-temperature range. As new petrographic observations accumulated, it became increasingly difficult to accommodate this information within a manageable framework of metamorphic facies and subfacies. Instead, it turned out that mineral assemblages due to reactions in common rocks of a particular composi- tion provide suitable indicators of metamorphic conditions. Metamorphic zones, defined on the basis of mineral reactions, very effectively display the evolution of metamorphic rocks. Thus the im- portance ofreactions in metamorphic rocks is emphasized. Experimen- tal calibration of mineral reactions makes it possible to distinguish reac- tions which are of petrogenetic significance from those which are not. This distinction provides guidance in petrographic investigations un- dertaken with the object of deducing the physical conditions of metamorphism.
