Book Description
This report is part of an ongoing study to characterize both sequence stratigraphy and chronostratigraphy of the Baker Lake Basin, Nunavut. The investigators examined well-exposed segments of the basin in detail, emphasizing sequence stratigraphic analysis to identify genetic packages of strata related to tectonically controlled basin-filling rhythms. Three sections exposed at the western edge of Thirty Mile Lake have been measured and correlated, yielding data on five depositional sequences. After an introduction on the geologic setting of the study area, the report provides facies assemblage descriptions and interpretations of the five depositional sequences of the lower Baker Lake Group. Finally, the accommodation (or space made available for a sedimentary system to fill) cycle in the basin is discussed and conclusions are drawn regarding the subsidence mechanism in the basin.

Book Description
The idea for a book on anorthosites came to me in January of 1986 while returning to Houston after holiday festivities in Dallas. The original idea was a review paper on anorthosites, but by the time I reached Houston, the subject material I contemplated induding was obviously too extensive for a single paper. The Director of the Lunar and Planetary Institute, Kevin Burke, was receptive to the idea of a book, and suggested that I contact Peter Wyllie, who serves as Editor of the Springer-Verlag series Minerals and Rocks. This effort, which I originally expected would take about a year, has taken nearly 6. I have many excuses- indolence, moving to another continent, other commitments, etc.-but the basic truth is that writing a book is much larger an undertaking than can be anticipated. Many people are aware of this, and I was duly forewarned. . But why write a book on anorthosites? This is a very good question, which I have considered from many angles. One rationale can be expressed in terms of a comparison between anorthosite and basalt. A first-order understanding of basalt genesis has been extant for many years. By contrast, there is little agreement about the origin of anorthosite. There are good reasons for studying and writing about basalt: it is the most abundant rock type on the Earth's surface, and is also plentiful on the surfaces of the other terrestrial planets.

Book Description
Formation resistivity factor and pore-surface resistivity values were determined for three mineralized & nonmineralized rock samples from the Giant mine & Con mine areas of the Yellowknife mining district. The purpose was to provide basic information required to understand the electrical conductivity mechanisms of these rocks and to aid interpretation of geophysical surveys conducted in these areas. This paper describes the methods & processes used to obtain the formation factor data & to document the results for use in future studies.

Book Description
Reports findings of reconnaissance seismic surveys conducted on the north-east Grand Bank to study the near-surface sediments, assess the presence and characteristics of seabed geotechnical hazards, and examine the role of Quaternary glaciation and sea-level fluctuation on sediment distribution and characteristics. The regional setting is first reviewed and a refined regional stratigraphy is described based on new seismic data. Till deposits and moraine fields as observed from the seismic studies of the shelf glacial sediments are described. Finally, interpretations of the glacial history of the study area are offered and implications of the findings for offshore engineering related to oil & gas development are discussed.

Book Description
This volume presents work focused on underrepresented persons in a variety of levels of higher education. Each scholar has used critical quantitative approaches to examine access and/or success in the higher education arena. Their scholarship pushes the boundaries of what we know by questioning mainstream notions of higher education through: the examination of policies the re-framing of theories and measures the reexamination of traditional questions for nontraditional populations. The work is divergent, but the commonality of the presentations lies in each scholar’s critical approach to conventional quantitative scholarship. Their research highlights inequities and explores factors not typically included in conventional quantitative analysis. This is the 158th volume of this Jossey-Bass quarterly report series. Always timely and comprehensive, New Directions for Institutional Research provides planners and administrators in all types of academic institutions with guidelines in such areas as resource coordination, information analysis, program evaluation, and institutional management.

Book Description
Since its inception in 1966, the series of numbered volumes known as Semiconductors and Semimetals has distinguished itself through the careful selection of well-known authors, editors, and contributors. The Willardson and Beer series, as it is widely known, has succeeded in producing numerous landmark volumes and chapters. Not only did many of these volumes make an impact at the time of their publication, but they continue to be well-cited years after their original release. Recently, Professor Eicke R. Weber of the University of California at Berkeley joined as a co-editor of the series. Professor Weber, a well-known expert in the field of semiconductor materials, will further contribute to continuing the series' tradition of publishing timely, highly relevant, and long-impacting volumes. Some of the recent volumes, such as Hydrogen in Semiconductors, Imperfections in III/V Materials, Epitaxial Microstructures, High-Speed Heterostructure Devices, Oxygen in Silicon, and others promise that this tradition will be maintained and even expanded.Thermoelectric materials may be used for solid state refrigeration or power generation applications via the large Peltier effect in these materials. To be an effective thermoelectric material, a material must possess a large Seebeck coefficient, a low resistivity and a low thermal conductivity. Due to increased need for alternative energy sources providing environmentally friendly refrigeration and power generation, thermoelectric materials research experienced a rebirth in the mid 1990's. Semiconductors and Semimetals, Volume 70: Recent Trends in Thermoelectric Materials Research: Part Two provides an overview of much of this research in thermoelectric materials during the decade of the 1990's. New materials and new material concepts such as quantum well and superlattice structures gave hope to the possibilities that might be achieved. An effort was made to focus on these new materials and not on materials such as BiTe alloys, since such recent reviews are available. Experts in the field who were active researchers during this period were the primary authors to this series of review articles. This is the most complete collection of review articles that are primarily focussed on new materials and new concepts that is existence to date.

Book Description
The basal surface of the Bravo Lake Formation, central Baffin Island, represents a rapid, conformable transition from iron-enriched marine deposition to near-basin margin shallow marine volcanism. This report presents results of detailed structural, stratigraphic, & three-dimensional mapping of this basal surface in an area south-west of Nadluardjuk Lake. It includes information on the general geology of the area, stratigraphy, characteristics of exposed rocks, and structural geology.
