Our new perspective on possible cosmic causes of the tectonic phases as well as our attempt to elaborate a cyclostratigraphic chart of the Neogene for Central Paratethys, imposed a reconsideration of the key data on the Wallachian tectonic phase. Especially since this important moment was ?abolished? by some modern authors. The Wallachian phase was defined by Hans Stille in connection with the Neogene?Quaternary limit. But this German geologist relied on the data of Romanian geologists who published, from 1907 to 1924, comments of an orogenic post-Pliocene movement. Subsequently, the Wallachian phase was denied by Macovei, was confused by several authors with the Pasadenian phase or was converted into a sub-stage of the final stage of the Alpine orogenesis. Initially, the appearing of the famous diapir folds of the extra-Carpathian area was exclusively attributed to post-Pliocene movements, but their formation is due to a greater number of Neogene tectonic phases, older than Wallachian phase. However the real effects of this phase were special and that is why this marks an important geological limit. So, the Wallachian phase also marks the beginning of the restriction of the Dacian Basin, the beginning of the accumulation of the ?Candesti Formation?, but also the beginning of the volcanic activity in Persani Mts. However this phase is especially the main cause of the folding and faulting of Pliocene deposits in the Carpathian area, of the accentuation of the diapir folds, but also of the formation of some ellipsoidal and circular tectonic structures, identified by us in the same area. In our opinion, the Wallachian phase connected with the Raup-Sepkoski cycles (R-S cycles, reflecting pulsations of our galaxy), is the last term of a geodynamic series with rare terms (at about 13 ma) and is preceded, in the Neogene, only by one phase of this series (the New-Styrian phase). All other Neogene phases could be moments of another series, with a frequency of 2.05 ma, due to a different cyclicity: Valach climatic cycle, highlighted by us, that must reflect possible pulsations of the Solar System.
