Posted on , by luongquocchinh. Description Author: Andrew J. Barker Category: Geology Language: English Page: 1 ISBN: Description: Structured in the form of a dichotomous key, comparable to those widely used in botany, the mineral key provides an effi cient and systematic approach to identifying rock-forming minerals in thin-section. Commencing with a brief introduction to mineral systems, and the properties of minerals in plane-polarised and cross-polarised light, the mineral key also includes line drawings, tables of mineral properties and an interference colour chart, to further aid mineral identification. To minimise the chance of misidentification, and enable less experienced petrologists to use the key with confidence, the key has been arranged to prioritise those properties that are most easily recognised. Designed for simplicity and ease of use, it is primarily aimed at undergraduate and postgraduate students of mineralogy and petrology, but should also provide a valuable source of reference for all practising geologists dealing with rock thinsections and their interpretation.

Tritium is a radioisotope of concern in nuclear reactor waste streams. Isotopes and nucleosynthesis Main article: Isotopes of beryllium Both stable and unstable isotopes of beryllium are created in stars, but the radioisotopes do not last long. It is believed that most of the stable beryllium in the universe was originally created in the interstellar medium when cosmic rays induced fission in heavier elements found in interstellar gas and dust.

Plot showing variations in solar activity, including variation in sunspot number red and 10Be concentration blue.

Note that the beryllium scale is inverted, so increases on this scale indicate lower 10Be levels Radioactive cosmogenic 10Be is produced in the atmosphere of the Earth by the cosmic ray spallation of oxygen. Thus, 10Be and its daughter products are used to examine natural soil erosion , soil formation and the development of lateritic soils , and as a proxy for measurement of the variations in solar activity and the age of ice cores.

This is one of the indicators of past activity at nuclear weapon test sites. The British astronomer Sir Fred Hoyle first showed that the energy levels of 8Be and 12C allow carbon production by the so-called triple-alpha process in helium-fueled stars where more nucleosynthesis time is available.

This process allows carbon to be produced in stars, but not in the Big Bang. Star-created carbon the basis of carbon-based life is thus a component in the elements in the gas and dust ejected by AGB stars and supernovae see also Big Bang nucleosynthesis , as well as the creation of all other elements with atomic numbers larger than that of carbon. Therefore, when 7Be decays by L- electron capture , it does so by taking electrons from its atomic orbitals that may be participating in bonding.

Make sure you have a current version of QuickTime to view these. The frame rate is fairly high so you might need to pause the movie and step through with the cursor keys during teaching. Identification Tables for Common Minerals in Thin Section -- John Faithful, Hunterian Museum, University of Glasgow; comprehensive and easy to use tables of optical properties of the rock-forming minerals.

MicroView -- a Java aplet that allows you to see a variety of minerals and rocks in thin section and grain mount by rotating the field of view, and looking at the image in both plane polarized and cross-polarized light.

North Dakota State University. Petroglyph -- Eric Christiansen and others, Brigham Young University; a comprehensive tutorial that includes modules on the petrographic microscope, plane polaraized light, cross polarized light, reflected light, consoscopic light, electron microscope, and includes a variety of petrogrpahic tools, query functions, and a quiz mode.

Commercially available as a CD.

Optical Mineralogy and Petrography

Experiments in Crystal Optics -- Hans Dieter Zimmermann; The purpose of the experiments below is to impart an intuitive understanding of the interaction between light and crystals and thus, of optical crystallography.

This will help to demystify what is seen in the polarizing microscope and will better prepare students for the introduction of optical indicatrices as 3-D models to describe the directional dependence of light velocities, and thus refractive indices in anisotropic crystals.

Laboratory Exercises and Demonstrations with the Spindle Stage -- Mickey Gunter, University of Idaho; The goal of this lab session is to introduce you to the spindle stage and its possible uses in an undergraduate mineralogy lab. At the undergraduate level, it can be used to identify minerals and to demonstrate the relationships among grain shape, retardation, and interference figures.
