Are Corestones Due to Weathering and/or Tectonism? Problems and Suggestions
Twidale, C. R.; Vidal Romaní, Juan Ramón (Universidade da Coruña, Servizo de Publicacións, 2020-12-28)[Abstract] Many of the so-called corestones have been developed from rocky blocks that have been apparently affected by subsurface physicochemical weathering that results in lamination, granulation, and eventually a puggy ... -
Bornhardts, Bouldes and Inselbergs
Twidale, C. R. (Universidade da Coruña, 1995)[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 ... -

Horace R. Blank and the origin of rock doughnuts
Twidale, C. R. (2018)[Abstract] Rock doughnuts are annular rims developed around rock basins that intermittently carry pools of water. They are developed in granitic rocks, and in arenaceous and calcareous sediments and in coastal as wells as ... -

Multistage Landform Development in Various Settings and at Various Scales
Twidale, C. R.; Bourne, J. A.; Vidal Romaní, Juan Ramón (Universidade da Coruña, 2002)[Abstract] That many landforms have their origins in the distant past is highlighted by the multistage concept, whereby the structural properties of bedrock which have been exploited by shallow groundwaters are taken fully ... -

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 ... -
Reflections on the fate of some geomorphological ideas
Twidale, C. R. (Universidade da Coruña, 2001)[Abstract] In geomorphology, as in other sciences, investigation is concerned with the collection and characterisation of data, and the generation and testing of working hypotheses. Considering the analysis of landforms ... -
