    • 1901, Smithsonian Institution, Board of Regents, Annual Report of the Board of Regents of the Smithsonian Institution, page 427:

    • 1983, B. Simpson, Rock & Minerals, page 88:
      If the dyke is of great thickness the centre may be coarsely crystalline as a deep-seated plutonic rock and this makes it difficult to distinguish a dyke rock in hand specimen.
    • 2017, Chris Pellant, Helen Pellant, Geological Structures - An Introductory Field Guide, page 14:
      As a dyke is made of igneous rock, it is usually possible to date it by radiometric dating methods, which give an absolute age for the dyke rock.
