      [Abstract] Bornhardts are steep-sided domical hills. The profiles are associated with sheet fractures, and their plan form with steeply dipping fractures of orthogonal or rhomboidal systems. They are well developed in ...

    • Pruebas morfológicas y estructurales sobre el origen de las fracturas de descamación 

      Vidal Romaní, Juan Ramón; Twidale, C. R.; Campbell, E. M.; Centeno Carrillo, Juan de Dios (Universidade da Coruña, 1995)
      [Abstract] Sheet fractures are well and widely developed in massive rocks, i.e., rocks lacking other partings, and they have been discussed in the literature for more than a century. Yet there is no agreement as to their ...

      Campbell, E. M.; Twidale, C. R. (Universidade da Coruña, 1995)
      [Abstract] The many minor forms developed on granitic terrains, on bornhardts and other residual hilis, on boulders, on sheet structures and on platforms, vary in origino Different modes of initiation and subsequent ...
