Mineralogical data

Room-temperature fluorescence (RTF) has been used to determine the emission characteristics of a wide variety of materials relative to the wavelengths of selected Fraunhofer lines in support of the Fraunhofer luminescence detector remote-sensing instrument. RTF techniques are now used in the compilation of excitation-emission-matrix (EEM) fluorescence "signatures" of materials. The spectral data are collected with a Perkin-Elraer MPF-44B Fluorescence Spectrometer interfaced to an Apple 11+ personal computer. EEM fluorescence data can be displayed as 3-D perspective plots, contour plots, or "color-contour" images. The integrated intensity for selected Fraunhofer lines can also be directly extracted from the EEM data rather than being collected with a separate procedure. Fluorescence, chemical, and mineralogical data will be statistically analyzed to determine the probable physical and/or chemical causes of the fluorescence. 

A 40-km x 40 km sample spacing for the North American project will provide soil geochemical and mineralogical data that will display coherent and robust regional to continental-scale patterns, as also demonstrated by Smith and Reimann (2008). 

The geological work coupled with the quantitative, statistically representative and complete mineralogical data and input into a geometallurgical framework provides a strong foundation for the development of any project. 

We will explain in the following sections what new information may be obtained from morphology, perfection, and homogeneity in diamond crystals, in addition to the geological, geochemical, petrological, and mineralogical data. 

Walker Lake. Walker Lake, located in west-central Nevada, is a remnant of pluvial Lake Lahontan, which, at its high stand, had a depth of 280 meters (21). Walker Lake is the terminus of the Walker River. Although its salinity is only 30% that of seawater, its sulfate concentration is identical to that of seawater (0.028 mol/L). The Walker Lake samples represent 300,000 years of depositional history (Yang, unpublished report). Preliminary interpretations of paleontological and mineralogical data (Benson and Spencer, written communication) suggest that lake levels have fluctuated. 

Because sedimentary carbonates represent primarily chemical and biochemical precipitates from seawater, and because they make up 20% of the common sedimentary rock record, these rock types have been particularly good sources of chemical and mineralogical data for interpretation of the secular and cyclic evolution of the Earth s surface environment. This carbonate rock record as a function of geological age is now explored as are age trends in other rock types and sediment properties. With this information as background material, we can then discuss what these relationships tell us about the history of carbonates and the exogenic system throughout geologic dme. 

The last five chapters of the book are devoted to major applications of CBPCs. Chapter 14 covers CBPC matrix composites that are finding commercial applications in the United States. Discussed in Chapter 15 are drilling cements developed mainly by the U.S. Department of Energy laboratories with industrial collaborations. Applications of CBPCs in the stabilization of hazardous and radioactive waste streams are discussed in Chapters 16 and 17. Finally, recent advances in CBPC bioceramics are covered in Chapter 18. Appendixes A, B, and C compile relevant thermodynamic and mineralogy data that were useful in writing the book. They serve as a ready reference to researchers who venture into further development of CBPCs. 

There is a lot of confusion in the mineralogical data about manganese nodules. The most frequent manganese mineral in deep-sea manganese nodules is an 10 A manganate...

Models are applied to a system, or a portion of the observable universe separated by well-defined boundaries for the purpose of investigation. A chemical model is a theoretical construct that permits the calculation of chemical properties and processes, such as the thermodynamic, kinetic, or quantum mechanical properties of a system. A geochemical model is a chemical model developed for geologic systems. Geochemical models often incorporate chemical models such as ion association and aqueous speciation together with mineralogical data and assumptions about mass transfer to study water-rock interactions. 

In interpreting isotope distributions, attention must be paid to all relevant geological, geochemical and mineralogical data which may provide clues as to the environment prevailing at the time of deposition and the post-deposi-tional history of the deposit. 

Quantitative mineralogical data have been generated from sonic transit time, density and neutron... 

There is a general lack of mineralogical studies in site characterizations (Zhu and Burden, 2001). Actual mineral assemblages, both primary and secondary, their relative abundances, and spatial distributions are very important to the modeling results. However, detailed mineralogical data are seldom available. 

The mineralogical data reported above were obtained from X-ray diffraction analysis. However, this technique has distinct limitations when applied to the...

Peculiar geochemical (fig. 2) and mineralogical data (fig. 3) were obtained from the bentonite in the close proximity (20 - 30 cm) of the dike. 

An excellent application of SEM-AIA particle-size data was discovered in an investigation of pyrite oxidation as a result of a coal weathering (18). Table V summarizes mineralogical data obtained by SEM-AIA on a suite of four san5>les of Middle Kittanning coal. These san les were obtained from a strip mine...
