The first edition of this encyclopedia was published a decade ago, and some remarkable changes have occurred in the gemstone marketplace during this interval. Although diamond still retains its place as the most popular and esteemed of all gemstones, the extremely wide gap in this leadership position versus colored stones has nar- rowed. There is a large and growing demand for all kinds of gemstones, especially brightly colored stones that can be worn as fashion accessories. Beaded jewelry has become an item of immense popularity; pearls have seen a huge revival.

The Encyclopedia ofSedimentology is a comprehensive, alphabetical treatment of the discipline of sedimentology. It is intended to be a reference book for sedimentologists, geologists, and others who come in contact with sediments. In the broadest sense, this group includes most of the world’s population because over 75 percent of the earth’s surface is covered with sediments and sedimentary rocks. The book should be particularly useful, however, to petroleum and coal geologists, soil scientists, hydrologists, archaeologists, and other professionals in related fields.

I have been a lifelong dinosaur enthusiast. At the age of four, I created what my mother has dubbed my “first research paper”: a stack of illustrations of every different species I could find throughout the pages of my many dinosaur books.

I’ve collected dinosaur books throughout my life, and recently I embarked on a search for a very specific sort of tome: a truly comprehensive, informative, encyclopedic collection of all known dinosaurs.

I’ve collected dinosaur books throughout my life, and recently I embarked on a search for a very specific sort of tome: a truly comprehensive, informative, encyclopedic collection of all known dinosaurs. Needless to say, a wide variety of dinosaur-themed texts have been available throughout the years, but try as I might, I couldn’t locate any volume that really fit the bill.

The south-west Pacific Ocean is a region of isolated islands and submerged plateaus and ridges (Figure 1). The three main islands of New Zealand (North, South, and Stewart) make up the largest landmass group in the region. Schists, greywackes, and granitoids are exposed in islands on the Challenger Plateau and Chatham Rise and have been sampled in dredges on the Campbell Plateau and Norfolk Ridge, thus demonstrating their continental geological character.

Darwin’s tangled bank is the biosphere in poetic microcosm, and the “damp earth” he refers to is soil. Soil is arguably the most complex of all geological materials, a combination of mineral and organic constituents in solid, aqueous and gaseous forms, organized into a loose, porous, horizonated, plant-bearing material, that is constantly changing. It forms as a result of a complex series of interactions and feedbacks between lithosphere, hydrosphere, atmosphere and, biosphere. As the natural geological cover of most of the land surface of the earth, it is the focus of this encyclopedia.
