Download or read book Formation of Authigenic Minerals During Microbial Degradation in Artificial Marine Media written by Matthew Albert Henry Joss and published by . This book was released on 2015 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: I have conducted incubation experiments exploring microbial degradation of organic matter within an artificial sediment designed to simulate an organic-rich siliciclastic marine sediment. Central questions to my research include: 1) How does the presence of dissolved iron influence the degradation and/or protection of organic matter within sediments? 2) How does dissolved iron influence the development of authigenic minerals? 3) How do microbial metabolisms affect dissolved iron concentrations and authigenic mineral precipitation? My experimental system consisted of dead cyanobacterial cells that were mixed with acid-washed glass beads, thereby making an artificial sediment essentially free of contaminants. This material was deposited into incubation cultures with artificial marine liquid media with varying concentrations of dissolved Fe(III). The cultures were exposed either to a natural sediment community or to the iron-reducing facultative anaerobe Shewanella Putrefaciens, in oxia or in anoxia. These cultures were compared against controls that contained no living microbes. The liquid media had varying initial concentrations of dissolved iron. For cultures with initially 0.2 mg/L of dissolved Fe(III) or no initial dissolved Fe(III), I measure the extent of degradation through loss on ignition gravimetry after 40 days of incubation. I also measured pH levels, dissolved Fe(II), and total Fe over a period of 60 days. Scanning electron microscopy and energy dispersive X-ray spectroscopy were used to identify mineralized organic particles and mineral grains within subsamples of the living cultures. In contrast, the sterile controls had no recognizable mineralization present. Finally, X-ray diffraction spectra were obtained for sediment subsamples of cultures with initial iron concentrations of 0.1 mg/L, revealing spectral peaks indicative of small amounts of authigenic mineral structure present within the oxic living cultures. Iron is identified as a key component of many mineralized structures within the living samples, particularly in the anoxic samples, with iron rich particles usually being mostly amorphous. It is possible that longer incubation times would increase the extent of mineralization and produce divergent rates of organic matter protection and degradation.
Download or read book Marine Minerals written by Roger G. Burns and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 6 of Reviews in Mineralogy was originated from notes prepared for a short course on Marine Minerals held in La Jolla, California, November 2-3, 1979. Chapters in this volume are devoted to marine manganese oxide, iron oxide, silica polymorphs, zeolite, clay, phosphorite, barite, evaporite, and placer minerals. Carbonates are not included; coverage of this important mineral group warrants a separate monograph. The extremely interesting sulfide and hydrothermal mineral assemblages recently discovered at oceanic spreading centers are also not discussed here. Marine Minerals was first published in 1979 as Volume 6 of the series entitled Short course. In 1980 the Mineralogical Society of America changed the name of the series to Reviews in Mineralogy, and for that reason this, the second printing of Marine Minerals has been reissued under the new banner. Only minor corrections have been made.

Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Mineralogy provides comprehensive, basic treatment of the science of mineralogy. More than 140 articles by internationally known scholars and research workers describe specific areas of mineralogical interest, and a glossary of 3000 entries defines all valid mineral species and many related mineral names. In addition to traditional topics - descriptions of major structural groups, methods of mineral analysis, and the paragenesis of mineral species - this volume embraces such subjects as asbestiform minerals, minerals found in caves and in living beings, and gems and gemology. It includes current data on the latest in our geological inventories - lunar minerals. It describes the properties, characteristics, and uses of industrial resources such as abrasive materials and Portland cement. A directory will guide traveling mineralogists to the major mineralogical museums of the world, with their special interests noted. Clear technical illustrations supplement the text throughout. To help the student and professional find particular information there are a comprehensive subject index, extensive cross-references of related topics (whether in this volume or others in the series), and reference lists to background information and detailed advanced treatment of all topics. The Encyclopedia of Mineralogy is a valuable reference and source for professionals in all geological sciences, for science teachers at all levels, for collectors and `rock hounds', and for all who are curious about the minerals on earth or those brought back from outer space.

Available in PDF, EPUB and Kindle. Book excerpt: Clay minerals form in a wide variety of crustal environments, e.g. in soil profiles, in sediments at the surface and in deeply buried sedimentary deposits, and under regional, contact and hydrothermal metamorphism conditions. The book provides information about the dynamics of isotope systems in clays and helps us to understand the physical and chemical parameters in the transfer of masses within the crustal domain. Written for graduate students taking courses in sedimentary geochemistry, clay mineralogy, and soil mineralogy, the book will also appeal to scientists carrying out research on clay genesis and mass transfer in crustal environments.
Download or read book Geochemistry of Marine Sediments written by David J. Burdige and published by Princeton University Press. This book was released on 2020-08-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The processes occurring in surface marine sediments have a profound effect on the local and global cycling of many elements. This graduate text presents the fundamentals of marine sediment geochemistry by examining the complex chemical, biological, and physical processes that contribute to the conversion of these sediments to rock, a process known as early diagenesis. Research over the past three decades has uncovered the fact that the oxidation of organic matter deposited in sediment acts as a causative agent for many early diagenetic changes. Summarizing and discussing these findings and providing a much-needed update to Robert Berner's Early Diagenesis: A Theoretical Approach, David J. Burdige describes the ways to quantify geochemical processes in marine sediment. By doing so, he offers a deeper understanding of the cycling of elements such as carbon, nitrogen, and phosphorus, along with important metals such as iron and manganese. No other book presents such an in-depth look at marine sediment geochemistry. Including the most up-to-date research, a complete survey of the subject, explanatory text, and the most recent mathematical formulations that have contributed to our greater understanding of early diagenesis, Geochemistry of Marine Sediments will interest graduate students of geology, geochemistry, and oceanography, as well as the broader community of earth scientists. It is poised to become the standard text on the subject for years to come.
