Definition of schistose in English:

schistose

adjective ˈʃɪstəʊs
  • (of metamorphic rock) having a laminar structure like that of schist.

    〔地质〕(变形岩石)片岩结构的

    Example sentencesExamples
    • The metamorphic grains are composed of 100% quartz except for a small number with schistose textures that contain aligned mica.
    • Southwards along section towards the Sach Pass, the leucogranites gradually decrease in abundance and the pelitic rocks becomes more schistose.
    • Also observed, but far less common, are fine-grained silver, pink, or pale red schistose varieties.
    • With increasing content of white mica the fabric changes from massive to schistose.
    • The amphibolite is mostly medium grained, rather schistose and has a characteristic reddish hue on weathered surfaces.

Derivatives

  • schistosity

  • nounʃɪsˈtɒsɪtiˌʃɪsˈtɑsədi
    • Granite veins cut pelitic schists at a high angle but the veins are not folded, showing that the main schistosity predates emplacement.
      Example sentencesExamples
      • In the northern part of the range, no pervasive brittle deformation features were recognized and only local reactivations of the regional schistosity by right-lateral faulting was documented.
      • Further evidence of multiphase folding is given by crenulation or microfolding with hinge zones a centimetre or so apart which crinkle an earlier cleavage or schistosity.
      • In the area sampled, there is considerable variation in the orientation of the schistosity and consequently the amount of rotation will vary from site to site.
      • Brittle faulting is subparallel to the regional subvertical schistosity, indicating that it was superimposed in a broad region that has earlier experienced ductile-dominated deformation.
