Описание: This book investigates time as it affects taphonomy. All taphonomic agents operate through time, which may be long or short, so time adds another dimension to taphonomic change. The processes and modifications recorded in fossils can tell us how long the fossils took to accumulate and the geological/biological/ environmental context in which they fossilized. Measuring time in taphonomy requires long-term studies of taphonomic processes operating at the present time. In 1976, one of the authors (PA) started a 30-year monitoring project of animals that died natural deaths at Neuadd in Wales. The study area of 680ha of upland heathland, woodland and rough grazing were monitored. Over 100 sheep, horses, foxes, badgers, rabbits and small mammals were monitored, but only 56 yielded useful results. YFJ has also begun a similar study at Riofrio in Spain, and other long-term studies are reviewed. This 30-year study highlighted several time-specific taphonomic issues. Trampling of Neuadd specimens produced pitting and superficial scratching found commonly on fossils. Longer striations mimicking cut marks are common, particularly on bones in rocky substrates. The number and morphology of these pseudo-cut-marks are compared with cut marks made during human butchery. There is only a weak relationship with exposure time. The extreme effects of water and wind at Neuadd quickly dispersed body parts. Modifications similar to trampling and butchery were produced in running water. In still water, three modification stages are identified: Stage 1, which is 3-5 years with broad flaking; stage 2, 10-12 years with extreme flaking and loss of surface bone; and stage 3, >18 years with deep tissue loss. Weathering at Neuadd has a time-scale that is different from the one established for tropical environments: At 0-5 years, 92% of bones are unweathered, with 8% at stage 1; at 6 to 10 years, 73% of bones are unweathered, with 27% at stage 1; at 15 to 25 years, 17% of bones are unweathered, with 63% at stage 1 and 20% of bones at stage 2; at 30 to 35 years, only one skull survived, and it is at stage 1 weathering. Monitoring of buried bones at Neuadd shows three time-scales of modifications resulting from soil corrosion: Progressive corrosion under dense vegetation cover with high humidity from 2 to 23 years; increasing root marks from 2 to 23 years; and corrosion from the action of lower plants such as moss and algae in 3 to 11 years. The extent and sizes of carnivore and herbivore chewing marks was found to have no usable timescale. Dispersal of bones is slow at Neuadd and is related strongly both to the nature of the environment and to the size of the animals. Three timescales have been identified: Dispersal over 15 years is greatest for large animals in open environments, lower for medium sized animals like sheep, and the least for small and medium size animals in dense vegetation. Future monitoring projects could use electronic marking chips on single specimens, camera traps, GPS, the Global Weathering Project, radioactive markers on bones, and aerial mapping, backed up with experimental work in controlled conditions.

Описание: An Introduction to Aluminosilicates first reviews the main advances in the methods of obtaining synthetic montmorillonite for environmental and biomedical applications. Polyhydroxy metal complexes of Al, Fe, Zr, Cr and Ti (inorganic pillarizing agents) are studied for the synthesis of pillared clays. Information is provided on the possibility of using amorphous aluminosilicates as a modifying additive in the formulation of cement-based dry building mixtures. The physicochemical properties of the additive are considered, and the results of XRD and DTA analyzes are presented. The authors investigate the molecular orientation and surface morphology of organized molecular films with regard to solidastate structures for organo-modified aluminosilicates by a surface pressure-area isotherm, in-plane and out-of plane X-ray diffraction, and atomic force microscopy. A new method for the synthesis of amorphous mesoporous aluminosilicates with acidic properties and a narrow pore size distribution in the range of 2-7 nm is also explored. The urease immobilization of composite adsorbents polyacrylamideabentonite, polyacrylamideachitosan, and polyacrylamideachitosanabentonite is assessed, produced from polyacrylamide as a hydrogel, bentonite as an aluminosilicate mineral, and chitosan as a polysaccharide. Following this, the authors provide a brief overview of literature data where crystalline aluminosilicates have been utilized for the capture and immobilization of radionuclides. The physiochemical properties of as-synthesized layered aluminosilicate are characterized by small angle PXRD, FTIR, porosity studies, thermal studies, 27Al MAS NMR, and morphological studies. Subsequently, this compilation addresses the way in which magnetic nanoparticles have proven to be frequently occurring building blocks for hybrid structure construction and, moreover, have shown innovative prospects as multifunctional adsorbents. Modern methods for the synthesis of highly dispersed micro- and micromesoporous mordenite with a high degree of crystallinity, as well as high crystallinity mordenite with a hierarchical porous structure, methods for modifying the mentioned crystalline aluminosilicates as a result of postsynthetic treatments, and modern adsorption and catalytic systems based on them are described. Next, the high activity and selectivity of high crystallinity zeolite Y with a hierarchical porous structure in the synthesis of practically important oligomers of various unsaturated compounds is established. The adsorptive features of PAAm-Ch-Z for Th4+ are investigated in view of its dependency on pH, concentration, time, temperature and ionic strength. The parameters derived from the compatibility of experimentally obtained data to Langmuir, Freundlich and Dubinin-Radushkevich, van tHoff, pseudo frist-/second-order and Weber Morris models are utilized in the evaluation of adsorption and its thermodynamics and kinetics. Based on the importance and wide use of industrial kaolin, the penultimate chapter focuses on two materials that may be produced from metakaolin: geopolymers and synthetic zeolites. The applications of kaolin in the production of geopolymers has been studied in order to obtain geopolymer matrices with different application potentials. Lastly, the authors consider a possible mechanism for the generation of an acetyl-zeolite intermediate via transfer from different acetyl donors through theoretical studies using a cluster model of H-ZSM-5 zeolite designed by three TO4 tetrahedral units.

Описание:

Petrochronology is a rapidly emerging branch of Earth science that links time (ages or rates) with specific rock-forming processes and their physical conditions. It is founded in petrology and geochemistry, which define a petrogenetic context or delimit a specific process, to which chronometric data are then linked. This combination informs Earth's petrogenetic processes better than petrology or geochronology alone. This volume and the accompanying short courses address three broad categories of inquiry.　Conceptual approaches chapters　include petrologic modeling of multi-component chemical and mineralogic systems, and development of methods that include diffusive alteration of mineral chemistry.　Methods chapters　address four main analytical techniques, specifically EPMA, LA-ICP-MS, SIMS and TIMS.　Mineral-specific chapters　explore applications to a wide range of minerals, including zircon (metamorphic, igneous, and detrital/Hadean), baddeleyite, REE minerals (monazite, allanite, xenotime and apatite), titanite, rutile, garnet, and major igneous minerals (olivine, plagioclase and pyroxenes). These applications mainly focus on metamorphic, igneous, or tectonic processes, but additionally elucidate fundamental transdisciplinary progress in addressing mechanisms of crystal growth, the chemical consequences of mineral growth kinetics, and how chemical transport and deformation affect chemically complex mineral composites. Most chapters further recommend areas of future research.

Описание: Open system behavior is predicated on a fundamental relationship between the timescale over which mass is transported and the timescale over which it is chemically transformed. This relationship describes the basis for the multidisciplinary field of reactive transport (RT). In the 20 years since publication of Review in Mineralogy and Geochemistry volume 34: Reactive Transport in Porous Media, RT principles have expanded beyond early applications largely based in contaminant hydrology to become broadly utilized throughout the Earth Sciences. RT is now employed to address a wide variety of natural and engineered systems across diverse spatial and temporal scales, in tandem with advances in computational capability, quantitative imaging and reactive interface characterization techniques. The present volume reviews the diversity of reactive transport applications developed over the past 20 years, ranging from the understanding of basic processes at the nano- to micrometer scale to the prediction of Earth global cycling processes at the watershed scale.??Key areas of RT development are highlighted to continue advancing our capabilities to predict mass and energy transfer in natural and engineered systems.
