Download or read book Mineral Micro-Geochemistry Constraints on Petrogenesis and Genesis of Gold Deposit written by Yayun Liang and published by Springer Nature. This book was released on 2021-03-10 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Mineral Paragenesis, Geochemistry and Geochronology Investigations of the Carlin-type Gold Deposits at the Goldstrike Property, Northern Nevada by : Carolina Michelin de Almeida
Download or read book Mineral Paragenesis, Geochemistry and Geochronology Investigations of the Carlin-type Gold Deposits at the Goldstrike Property, Northern Nevada written by Carolina Michelin de Almeida and published by . This book was released on 2009 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Goldstrike property is located in northern Nevada and contains one of the largest and highest-grade Carlin-type gold deposits. The majority of the Eocene Au mineralization (e.g., Ore I) is hosted in intensely altered Paleozoic lower-plate impure carbonate rocks, and is characterized by strong to moderate silicification, higher calculated pyrite and ore-related element concentrations (e.g., As, Cu, Hg, Ni, Tl, Sb, W, and Zn) than Ore II, which is weakly altered. However, both ore types contain similar Au concentration in whole rock and pyrite chemistry analyses. Lithogeochemical and microprobe data suggest that the Paleozoic sedimentary rocks may have been a major source of Cd, Mo, Ni, U, V, and Zn and minor As, Cu, Hg, and Se. The Jurassic lamprophyre dikes might have been a significant source of Ba, Co, and Se, and minor Au, and some of the Jurassic and Eocene intrusive rocks may have provided some Fe. Moreover, the Eocene magmas are interpreted to be the main source of auriferous mineralizing fluids and ore-related elements. Trace element abundances and ratios of the Jurassic intrusive rocks suggest that they are shoshonitic and formed from a metasomatized mantle-derived magma, crystal fractionation, and crustal contamination. The Eocene dikes, also shoshonitic, are considerably more evolved and contaminated than the studied Jurassic rocks. Furthermore, Ar-Ar results show that the Jurassic intrusive rocks were negligibly affected by the Eocene thermal event, and that temperature of mineralizing fluids were below the closure temperature of biotite (> 3500C). A magmatic-related model is proposed to explain the formation of the Carlin-type gold deposits at the studied area. In this model, Au and the ore-related elements were exsolved along with volatiles by degassing of a deep and large plutonic complex during its early stage of crystallization. As these magmatic-hydrothermal fluids moved upward along major conduits (e.g., NNW-striking faults), they may have interacted with a Fe-rich fluid, pervasively altering the Paleozoic impure carbonate rocks (e.g., carbonate dissolution, silicification, pyritization) and forming Ore I. Subsequently, these fluids moved laterally further away from the major conduits, became cooler, less acidic, and depleted in ore-related elements and interacted with the Fe-bearing host rocks (e.g., sulfidation), favoring the precipitation of Ore II.

Book Synopsis Potassic Igneous Rocks and Associated Gold-Copper Mineralization by : Daniel Müller
Download or read book Potassic Igneous Rocks and Associated Gold-Copper Mineralization written by Daniel Müller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potassic igneous rocks have gained much attention among petrologists worldwide, mainly due to their distinct geochemistry, and many geoscientists still consider them as petrological curiosities with an obscure petrogenesis. In the past, a plethora of genetic hypotheses and of local names for potassic igneous rocks from different localities have been created. This has produced some confusion in the literature. This book reviews the geochemical and petrological characteristics of the potassic igneous rock complexes and investigates the different tectonic settings in which these rocks occur. The authors provide an overview and a classification of these rocks and attempt to elucidate the geochemical differences between barren and mineralized potassic igneous complexes. Many epithermal gold and porphyry copper-gold deposits are hosted by high-K rocks. Therefore, this book is not only relevant to academic petrologists working on alkaline rocks, but also to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terranes. This third, updated and enlarged edition contains several new sections, new geochemical data and additional references.

Book Synopsis Alkaline Rocks and Carbonatites of the World, Part 4 by : A.R. Woolley
Download or read book Alkaline Rocks and Carbonatites of the World, Part 4 written by A.R. Woolley and published by Geological Society of London. This book was released on 2019-09-02 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alkaline igneous rocks and carbonatites are compositionally and mineralogically the most diverse of all igneous rocks and, apart from their scientific interest, are of major, and growing, economic importance. They are important repositories of certain metals and commodities, indeed the only significant sources of some of them, and include Nb, the rare earths, Cu, V, diamond, phosphate, vermiculite, bauxite, raw materials for the manufacture of ceramics, and potentially Th and U. The economic potential of these rocks is now widely appreciated, particularly since the commencement of the mining of the Palabora carbonatite for copper and a host of valuable by-products. Similarly, the crucial economic dominance of rare earth production from carbonatite-related occurrences in China, has stimulated the world-wide hunt for similar deposits. This volume describes and provides ready access to the literature for all known occurrences of alkaline igneous rocks and carbonatites of Antarctica, Asia and Europe excluding the former USSR, Australasia and oceanic islands. More than 1,200 occurrences from 59 countries are outlined together with those of 57 oceanic islands and island groups. The descriptions include geographical coordinates and information on general geology, rock types, petrography, mineralogy, age and economic aspects with the principal references cited. There are 429 geological and distribution maps and a locality index. As has been demonstrated by the three earlier volumes, the present book is likely to be of considerable interest to mineral exploration companies, as there are no comprehensive published reviews of the economic aspects of the alkaline rocks. It will also interest research scientists in the fields of igneous petrology and volcanology, and geologists concerned with the regional distribution of igneous rocks and their geodynamic relationships.
Book Synopsis Siberian Traps and Pt-Cu-Ni Deposits in the Noril’sk Area by : Nadezhda A. Krivolutskaya
Download or read book Siberian Traps and Pt-Cu-Ni Deposits in the Noril’sk Area written by Nadezhda A. Krivolutskaya and published by Springer. This book was released on 2015-12-09 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses fundamental problems in the evolution of magmatic and ore-forming processes in the Noril’sk area of northern Central Siberia. Based on data on the geology and geochemistry of rocks, obtained by the author in the course of fieldworks and new analytical studies (applying XRF, ICP-MS, microprobe analysis, ion-probe analysis and studying melt and fluid inclusions in olivine, as well as stable and radiogenic isotopes in the rocks), it was proposed a new scheme for the evolution of magmatism, including two episodes: rift and trap per se. The ultramafic-mafic massifs are classified into three geochemical types, the most important of which (the ore-bearing Noril’sk type) was formed in post-Nadezhdinsky time as an independent pulse of magmatic activity. The primary melts for ore-bearing intrusions had tholeiitic composition with elevated MgO (8 wt%) and low volatile contents (data form melt inclusions in olivine and pyroxenes, in combination with numerical simulations using the COMAGMAT program package). The assimilation of host rocks by the parental melts was studied in the contact zones of the Maslovsky and Talnakh intrusions. It was shown that it had taken place only in narrow zones (about 1-2 m) and did not played sufficient role in ore formation. It was suggested that the source of the material was lower crustal rocks in long-lived rift zones, where sulfides accumulated in several stages. The book offers a valuable resource for specialists in the geology of ore deposits and petrology, as well as for advanced Geology students.

Book Synopsis Recent Advances in Understanding Gold Deposits by : T. Torvela
Download or read book Recent Advances in Understanding Gold Deposits written by T. Torvela and published by Geological Society of London Special Publications. This book was released on 2022-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold occurs in many settings, but the dynamic nature of Earth’s crust means overlapping and overprinting deposit styles are common. Characterization of mineralization from an early stage becomes important, particularly where the mineralization is complex, in order to maximize exploration and project development success and mining productivity. Various techniques are used at different stages of a project to characterize gold deposits. This Special Publication offers a cross-section of some specific techniques used to investigate a variety of gold deposit types. The papers highlight both the breadth of the available techniques and their utility in deposit characterization, but also the many significant remaining questions and problems related to the exploration and research of gold deposits. Several papers include suggestions of avenues for fruitful further research, including a paper discussing a new approach to classifying orogenic gold deposits, and a paper describing archaeological applications of natural gold analyses.
Book Synopsis Potassic Igneous Rocks and Associated Gold-Copper Mineralization by : Daniel Müller
Download or read book Potassic Igneous Rocks and Associated Gold-Copper Mineralization written by Daniel Müller and published by Springer. This book was released on 2018-06-11 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the geochemical and petrological characteristics of potassic igneous rock complexes, and investigates the various tectonic settings in which these rocks occur. The authors provide an overview and classification of these rocks and elucidate the geochemical differences between barren and mineralized potassic igneous complexes. High-K rocks are genetically associated with a number of epithermal gold and porphyry copper-gold deposits. In recent years, there has also been growing recognition of an association of such rocks with iron-oxide copper-gold (IOCG) deposits, intrusion-related gold deposits (IRGDs) and Carlin-type gold deposits. This fifth updated and expanded edition incorporates new data and references from world-class copper and gold deposits worldwide. It also includes the latest publications on the petrogenesis of high-K magmatism and related mineral deposits. Numerous new representative ore photographs of the mineral deposits described are also included in the new edition. As such, the book offers a valuable guide not only for academic petrologists working on alkaline rocks, but also for exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terrains.
