Movimientos verticales de las fallas alpinas NE-SO del Macizo Ibérico en la región de Lugo

Abstract

The vertical component of the movement associated to a fault system striking NE-SW has been determine using geomorphic and structural observations. These faults are located in the Iberian Massif in the Lugo region. The results of both kind o f observations have coincided in characterising these faults as hinge and pivotal faults. Moreover, considering the different periods of time recorded by these methods, we can establish that these faults are Tertiary and it is very difficult to explain a previous origin because of the structure complexity and the coincidence of the measures. In addition, and according to the results obtained from this area, we believe that the measures taken from the geomorphic markers, can be used alone as reliable indicators of the vertical component in this kind of faults, especially in areas where there are no others indicators.
