Negru-Voda and Dragos. Legend and Historical Truth at the beginning of the Romanian Statehood
Radu Carciumaru
Codrul Cosminului , 2009,
Abstract: L’article se déploie sous la forme d’une étude comparative de deux personnalités, Negru-Vo vode et Drago , qui conformément à la tradition, ont conduit à la réalisation des formations d’Etat roumaines. Nous avons suivi le long du texte à mettre en valeur la base historique réelle sur laquelle peuvent siéger les deux légendes, même si entre elles il y a un décalage chronologique d’environ une demie de siècle. Justement à cause de cela, l’analyse proprement-dite est partie des moments identifiés clairement au niveau documentaire. De cette manière, l’arrivée de Negru-Vo vode est associée avec la rentrée d’Ugrinus, l’ancien voivode de la Transylvanie, le propriétaire des domaines de F g ra , pendant que le moment de l’arrivée de Drago est placé dans le contexte de l’expédition lancée par la couronne hongroise au sud de la Moldavie pour l’écartement des armées tatares.Evaluant une bonne partie des contributions bibliographiques liées du problème de la genèse des Etats médiévaux, nous avons tiré la conclusion que les apparitions des légendes de Negru-Vo vode et Drago dans le processus de finalisation des Etats roumains ont à la base des raisons semblables, dans le sens que leur premier objectif est illustré par le désir de remplir un vide documentaire présent pour une période de quelques décennies, au sud, mais aussi, à l’est des Carpates.
On the origin of low angle normal faulting in the Southern Rio Grande Rift
Carciumaru, Dana;Ortega, Roberto;
Geofísica internacional , 2011,
Abstract: we reconstruct the stress regime in the east potrillo and franklin mountains. using modern numerical techniques the stress field and the tectonic history of this region is discussed and extensional veins were compared with the general stress field. the majority of faults were reactivated during the first rio grande rift extensional event and occurrence of extensive tilting and rotations occurred. in the east potrillo mountains, back tilting by w25°se and w45°se oriented along strikes of n30°w are required in order to obtain two homogeneous stress fields. the corrected fault plane shows a significant oblique component in both stress fields. the first stress field corresponds to a fault reactivation with σl and σ3 oriented n78°e and n69°e respectively, whereas the second stress field is related to the youngest fault oriented n64°w and n61°e respectively. in the franklin mountains, tilting is less significant; however two stress fields with similar orientations but different phi values are recognized. the post -laramide stress history of the region is controlled by different extensional events that influenced the preexisting structures and generated other young fault systems.
Geologic structure of the northern margin of the Chihuahua trough: Evidence for controlled deformation during Laramide Orogeny
Carciumaru, Dana;Ortega, Roberto;
Boletín de la Sociedad Geológica Mexicana , 2008,
Abstract: in this article we studied the northern part of the laramide foreland of the chihuahua trough. the purpose of this work is twofold; first we studied whether the deformation involves or not the basement along crustal faults (thin- or thick- skinned deformation), and second, we studied the nature of the principal shortening directions in the chihuahua trough. in this region, style of deformation changes from motion on moderate to low angle thrust and reverse faults within the interior of the basin to basement involved reverse faulting on the adjacent platform. shortening directions estimated from the geometry of folds and faults and inversion of fault slip data indicate that both basement involved structures and faults within the basin record a similar laramide deformation style. map scale relationships indicate that motion on high angle basement involved thrusts post dates low angle thrusting. this is consistent with the two sets of faults forming during a single progressive deformation with in - sequence - thrusting migrating out of the basin onto the platform. we found that the style of deformation in the chihuahua trough is variable. in places such as the east potrillo mountains and indio mountains is typical of the thin- skinned style, associated with the cordilleran thrust belt, while in other places, the thick - skinned deformation present is typical of the laramide orogeny in the southern rocky mountains. the franklin mountains record the transition from thick- to thin - skinned deformation. we notice that this difference in the style of deformation is related to the thickness of the cretaceous section within the chihuahua trough. on the other hand, the orientation of the shortening direction can be explained based on the geometry of the trough and especially the strike of its eastern margin. along strike variations in shortening direction and kinematics are controlled by the curved northeast margin of the trough and reflect stress reorientation along the weak
