1999, Volume 84

G. Morin, J.D. Ostergren, F. Juillot, P. Ildefonse, G. Calas, and G.E. Brown, Jr., XAFS determination of the chemical form of lead in smelter-contaminated soils and mine tailings: Importance of adsorption processes. p. 420-434. Abstract

As mineralogists turn their attention to environmental problems, we must evaluate the capabilities of our instruments and find ways to make them answer significant environmental problems.  This paper evaluates lead contamination in soils, a problem with large environmental significance.  By ascertaining the chemical form of lead, knowledge of its bioavailability results, which is of fundamental importance to human health.

1998, Volume 83

R. Dohmen, S. Chakraborty, H. Palme and W. Rammensee, Solid-solid reactions mediated by a gas phase: an experimental study of reaction progress and the role of surfaces in the system olivine + iron metal p. 970-984. Abstract

This paper applies the novel technique of Knudsen-cell mass spectrometry, in conjunction with electron microprobe analysis and imaging, to a problem of immediate interest to mineralogists and cosmochemists - the origin of olivine rims on grains of meteoritic Fe metal. The results of the analytical studies are followed by numerical modeling of relevant diffusion relationships to yield an interpretation involving gas fluxing that is tantalizing if not highly convincing. This paper demonstrates, furthermore, the significance of planetary materials studies to the science of mineralogy.

1997, Volume 82

Teng, H. H., and Dove, P. M., 1997 Surface site-specific interactions of aspartate with calcite during dissolution: implications for biomineralization. p. 878-887. Abstract

It seems fitting that the American Mineralogist's first Best Paper Award recognizes work of a highly interdisciplinary nature, bringing together aspects of crystal structure - the very foundation of mineralogy - with modern geochemistry to address molecular scale processes that bear on our understanding of the interplay between minerals and life. Teng and Dove's elegant AFM study illustrates the important roles that crystal structure and, in turn, surface structure play in governing mineral reactivity in nature. By examining the influence that organic molecules exert on step orientation and behavior during calcite dissolution, they provide some tantalizing insight into possible ways in which organisms control the formation of crystals. What stands out in their paper is the clarity with which they have documented a rapid morphological change at a mineral surface and the implications of the process for biomineralization.
