Multivariate analysis of granitic micromodelate: comparative interpretation on the gnamma genesis and development in old massifs

[Abstract] Statistic analysis results of two microforms samples from differentiated geomorphic environment (Ourense, Galicia, Spain) are displayed in this paper. Explanation test recent contributions about the genesis and development of granitic micromodelate. Conclusion summarize as a whole significant questions in opening process, depth increase and present stage of gnammas

Development trends of tafoni forms (incipient stages)

[Abstract] Forms called tafoni, diversified in different stages, are complex natural systems. The systematic register of their measurements is performed in order to infer relative ages and to use the results to reconstruct landscape evolution. The analysis of depth measures of the cavities developed into several tafoni demonstrates, for incipient cases in Galicia (NW of Iberian Peninsula), trends with different evolutionary trajectories. Depth measures were processed with robust statistical techniques. The development of tafoni combines linear and non-linear phases. This behaviour is related to the increase of complexity through self-organisation

Varied evidence and significant test on subaerial degradation on granitic minor forms: several case analysis

[Abstract] This paper deals with a whole significant questions on the subaerial evolution stage in the granitic minor forms, starting from several gnammas database. First, the ratio depth values (maximum/minimum) are inspect at their theoretical interpretation, related to the expected exposure time for the cavity; the following analysis test differential thresholds in order to establish development patterns, outcome from multivariate statistical techniques application on varied geomorphic environments. The results discussion and derived explanation show that gnamma degradative process is contemporary to the agradative process in epigenic conditions; the present observations variety is associated to special nature and temporary change of the different mechanism regulator components (lithology, morphometry, denudation magnitude, geomorphological evolution and microtopography)

Control variables on the genesis and development of granitic modelate: analysis of microforms at the Macizo de Manzaneda (Galicia, NW Spain)

[Abstract] Morphometric analysis results from Manzaneda granitic massif(Galicia, Spain) is displayed. Field observations ofgnammas sample are subject to exploratory and multivariate techniques. Explanation results provide conclusion set to confirm the origin and development hypothesis ofthis micromodelate, weighting control variables involved in the same

Recursos gemorfológicos: evolución morfológica de las marmitas de erosión en el río Miño

5 páginas, 4 figuras.-- VII Simpósio Ibérico sobre a Bacia Hidrográfica do Rio Minho, Vilanova de Cerveira, 7-8 novembro 2014En el río Miño, que discurre en su mayor parte sobre granitos, se distinguen zonas en las que la corriente circula directamente sobre la roca madre con formas características de erosión fluvial. Una de las más comunes son las marmitas (potholes) que se van a generar en condiciones dependientes del régimen hídrico y la estacionalidad del flujo del río. Junto a otras formas, las marmitas son parte del patrimonio geomorfológico fluvial asociado al río Miño. En este estudio se presenta una secuenciación evolutiva diferenciada en cuatro fases, para las cuales se han establecido valores umbral que marcan cambios en la morfologíaPeer reviewe
