Planar defects in fibrous amphiboles

  • J. E. Chisholm
Papers

Abstract

The reciprocal lattice of the fibrous amphiboles is shown to consist of two sets of streaks or spikes, one parallel to x*, the other to y*. The first of these are interpreted in terms of stacking faults parallel to (100) with displacement ±∼ 1/3c. The pyroxene, amphibole and talc structures are described as a family related by crystallographic shear operations and the streaks parallel to y* ascribed to Wadsley defects parallel to (010).
