Nomenclature of Amphiboles; Report of the Subcommittee on Amphiboles of the International Mineralogical Association Commission on New Minerals and Mineral NamesAbstract The International Mineralogical Association's approved amphibole nomenclature has been revised in order to simplify it, make it more consistent with divisions generally at 50%, define prefixes and modifiers more precisely and include new amphibole species discovered and named since 1978, when the previous scheme was approved. The same reference axes form th... ...

A general equation for estimating Fe3+ concentrations in ferromagnesian silicates and oxides from microprobe analyses, using stoichiometric criteriaAbstract A simple general equation is presented for estimating the Fe3+ concentrations in ferromagnesian oxide and silicate minerals from microprobe analyses. The equation has been derived using stoichiometric criteria assuming that iron is the only element present with variable valency and that oxygen is the only anion. In general, the number o... ...

Unit cell refinement from powder diffraction data: the use of regression diagnosticsAbstract We discuss the use of regression diagnostics combined with nonlinear least-squares to refine cell parameters from powder diffraction data, presenting a method which minimizes residuals in the experimentally-determined quantity (usually 2θhkl Ehkl ). Reg... ...

Mineral replacement reactions: from macroscopic observations to microscopic mechanismsAbstract Mineral replacement reactions take place primarily by dissolution-reprecipitation processes. Processes such as cation exchange, chemical weathering, deuteric alteration, leaching, pseudomorphism, metasomatism, diagenesis and metamorphism are all linked by common features in which one mineral or mineral assemblage is replaced by a more stable assemblage. The... ...

Chemistry of chromian spinel in volcanic rocks as a potential guide to magma chemistryAbstract Chromian spinel in volcanic rocks is a potential discriminant for magma chemistry. The TiO2 content of spinel, compared at similar Fe3+ /(Cr + Al + Fe3+ ) ratios, can distinguish island arc basalts from intraplate basalts. MORB spinels are low in this ratio and are intermediate for the TiO...

Crystal structures of some double hydroxide mineralsSummary
Three groups of minerals are discussed,
which are typified by pyroaurite and sjögrenitc,
hydrocalumite, and ettringite. All show
interesting structural feature... ...

Atomic number and crystallographic contrast images with the SEM: a review of backscattered electron techniquesAbstract Backscattered electrons (BSE) are incident electrons reflected back from a target specimen and imaged with the scanning electron microscope (SEM). Three distinct BSE signals exist: atomic number or Z-contrast, in which composition determines image contrast; orientation contrast, in which specimen crystal structure determines image contrast; and electron cha... ...

The catalysis of mineral reactions by water and restrictions on the presence of aqueous fluid during metamorphismAbstract The problems of characterizing inter-granular regions and of estimating rates of intergranular diffusion in metamorphic rocks are discussed. Inter-granular regions can be anhydrous, hydrated but under-saturated with H2 O, or saturated with H2 O, but only in the latter case can a free aqueous fluid phase be present. Es... ...

Diamond formation in the deep mantle: the record of mineral inclusions and their distribution in relation to mantle dehydration zonesAbstract Studies of the inclusions contained in natural diamonds have shown the occurrence of minerals which must have formed at depths below the lithosphere and which may be closely matched with the silicate mineral assemblages determined by high pressure and temperature experimental studies for depths of 300 to 800 km in the Earth's mantle. The inclusions come pri... ...

Arsenic hazard in shallow Cambodian groundwatersAbstract Our recent discovery of hazardous concentrations of arsenic in shallow sedimentary aquifers in Cambodia raises the spectre of future deleterious health impacts on a population that, particularly in non-urban areas, extensively use untreated groundwater as a source of drinking water and, in some instances, as irrigation water. We present here small-scale haz... ...
