   • The rocks of dyke phase include viz. microgranite, rhyolite, trachyandesite, trachydacite in Siwana 2011, Rajesh Srivastava, Dyke Swarms: Keys for Geodynamic Interpretation, page 277:
   • One of the most striking features of this igneous cycle is the remarkably well-developed dyke-phase, which in general followed, though to some extent it overlapped, the plutonic phase. 1926, Frederick Henry Hatch, Alfred Kingsley Wells, The Petrology of the Igneous Rocks, page 490:
   • and I have failed to detect those similarities between the sill and dyke phase of the same magma, which may reasonably be expected on such a view. 1916, Geological Society of South Africa, Transactions - Volumes 18-24, page 46:
