Abstract/Notes | The amphiboles are the most complex group of rock-forming minerals, exhibiting wide chemical variation and a bewildering variety of parageneses. They are common constituents across the complete range of igneous rocks. In sedimentary rocks, amphiboles occur both as detrital and authigenic phases. In metamorphic rocks, amphiboles are important constituents from very low grade to high grade and over a wide variety of rock compositions. This study summarizes the existing body of knowledge on the crystallography and crystal chemistry of the amphiboles. It is shown that amphiboles belong to five principal structure-types, with space groups C2/m, P2/a, P2//1/m, Pnma, and Pnmn, but the C2/m and Pnma structures are by far the most common. The M(4) site is of major importance in amphibole crystal chemistry. Spectroscopic analysis data a presented and analyzed, and cation distributions in amphiboles, factors affecting cation ordering, oxidation-dehydroxylation characteristics, electrical, magnetic, and elastic properties, and deformation behavior in amphiboles are discussed in detail. |
