Investment decisions are critical part of a company’s success, and capital budgeting is a central topic of financial management. However, in contrast to other strategic decisions in business, decisions on capital projects are decentralized, from corporate to divisions, divisions to operations, from operations to departments. Engineers at various levels within the organization who make a capital proposal are contributing to the strategic success of the organization. This book will assist engineers to contribute strategically to the organization, so that they can contribute to the success of their company and can make a success of their careers.<...>
The current book continues the work of Winterwerp and Van Kesteren (2004) and Mehta (2013). Our main objective is to provide guidelines for good modeling practice to quantify the transport and fate of fine sediment in open water, with emphasis on the marine environment. We emphasize that a (numerical) model should never be an objective by itself. It is always a tool to help answering managerial or engineering questions, or to enhance our understanding of nature. Yet, in this book we do not elaborate on how to use a model as a tool, as this is too unique an issue.

Fine-grained, mud-rich turbidite systems primarily occur in basins with a large fluvial input. Depositional models derived from sand-rich turbidite systems are not appropriate because the large volume of mud in fine-grained turbidite systems produces different sediment distribution patterns, geomorphic features, and internal architecture at bed-to-sequence scales. Many of the chapters in this volume demonstrate that understanding fine-grained turbidite systems requires a number of steps and degrees of resolution, very similar to the range of data utilized in the oil industry. Industrial examples include 2-D and 3-D seismic, cores, and well logs. To refine the understanding of a turbidite field, the earth scientist must integrate the most applicable models with subsurface data, outcrop analyses, modern analogs, and experimental results. <...>
Thin continuous laminated bedding-parallel quartz veins (BPVs) with slip-striated and fibred vein walls occur within slates, or at their contact with sandstones, on the limbs of chevron folds in the Bendigc-Castlemaine goldfields, southeastern Australia. Two microstructural Types of BPV (I and II) have been previously recognized, and are confirmed in this study. Both types are concluded to have formed during and/or after crenulation cleavage (the first tectonic axial planar structure) in the wallrock slates, and during flexural-slip folding. Type I BPVs consist of syntaxial phyllosilicate inclusion trails, parallel to bedding, enclosing inclined inclusion bands, the latter formed by detachment of wallrock phyllosilicate particles from the walls of pressure solution-segmented discordant tension veins. Type I BPVs are formed by bedding-parallel shear, and grow in width by propagation of the discordant veins into the BPV walls. Type II veins are composed of quartz bands separated by wallrock slate seams which have split away from the vein wall during dilatant shear opening. They incorporate numerous torn-apart fragments of crenulated wallrock slate. Type I BPV inclusion band average spacing of 0.5 mm probably represents the magnitude of slip increments during stick-slip flexural-slip folding activity

In 1949 a large bastn8site deposit was discovered at Mountain Pass, Cal if. Subsequent development of the deposit made the Uni ted States the worl d's largest source of rare-earth minerals. Since 1965, bastnisi te, a f luocarbonate of the cerium-group metals, REFC03, has replaced monazite as the principal source of rare earths; in 1978 it accounted for more than ha l f of the world production (§_).3 Rare-earth a lloys and compounds are used in petroleum crac.kin.g catalysts, ductile iron and high-strength, lo..,..alloy (HSLA) steel production, high- energy pertn4lnent magnets, color tel evi si on pi cture tubes, glass polishing and decolorizing, and ceramics. <...>

Faults and their deeper-level equivalents, shear zones are localized regions of higher strain which effectively accommodate differential movement in the Earth's crust and mantle during deformation of the lithosphere. Shear zones may be more precisely defined as approximately tabular regions of concentrated deformation and flow across which adjacent relatively undeformed rock units are offset.
