Horizontal stress Field evolution from Eocene to present in Neuquen Basin

Mostrar todas las versiones(3)

Continuity and evolution in time of the horizontal stress direction in the Neuquen Basin area, derived from the analysis of recent borehole data and orientation of volcanic dykes measured in outcrop in the Cara Cura and Reyes Ranges is presented. The bitumen dykes along the Neuquén Basin were formed...
