Abstract
The nine morphological types of caves developed in magmatic rocks that have differentiated until now are described. Of all of them, the river cave types of blocks and the roof erosion canyon cave are the largest and have the greatest longitudinal development. There are twelve cases of cave systems located in the W and NW of the Iberian Peninsula and located in Spain, (A Coruña, Cáceres, Lugo, Ourense and Pontevedra), and in Portugal, (Vila Real, North region). This allows us to show the phenomenon at different scales, review and outline the different processes that occur and interact in this particular medium.
