The problem of asbestiform particulates with its environmental and health implications has been compounded by the lack of precision with which the term "asbestos" has been used. In many instances, nonasbestiform mineral particles have been identified as microscopic fibers of asbestos-related minerals. This lack of precision in identifying these particulates not only works to the disadvantage of the minerals industry, but it also is a handicap to a rational science-based decisionmaking by regulatory agencies. This paper summarizes the methods and terminology suggested by the Bureau of Mines to identify and characterize mineral particles by morphological, compositional, and structural data using various instrumental analytical techniques and also sharpens the distinction between common serpentine and amphibole minerals and their relatively rare asbestiform varieties.
