Departamento de Geología

The Oviedo fold analysis group is a multi-disciplinary team formed mainly by members of the University of Oviedo (Spain). It was created in 1999 to gain insight into the 2D and 3D features of folds and fault-related folds. The research carried out by this team consists of:

  • Employing numerical, laboratory and field techniques to unravel the geometry, kinematics and mechanics of both experimental and natural (field and subsurface) folds
  • Developing new mathematical methods to analyse fold geometry, kinematics and mechanics

Research goals

Folds

  • Develop a theoretical method (direct and inverse algorithms) to unravel strain patterns on asymmetric fold profiles originated by superposition of folding steps involving different fold kinematic mechanisms (flexural-flow, tangential longitudinal strain and generalised homogeneous strain)
  • Unravel the strain state and the folding mechanisms in asymmetric natural folds (folds with cleavage from NW Spain and the Pyrenees, and recumbent folds in the Westasturian-leonese Zone and in the Helvetic nappes) knowing strain measurements and fabric analysis
  • Understand the variation of the folding mechanisms as a function of the rheological properties and thickness of the folded layers by applying the numerical methods to the strain analysis in folds obtained from experimental or finite element methods (synthetic folds)

Fault-related folds developed in different tectonic settings (contraction, extension, inversion)

  • Develop new tools to characterise the geometry and kinematics of fault-related folds
  • Determine the best algorithms to restore fault-related folds
  • Predict growth stratal, deformation and fracture patterns of fault-related folds: applications in natural resources exploration (underground water, minerals and hydrocarbons), geotechnical studies (tunnel and dump construction) and subsurface storage (radioactive waste disposal, CO2)
  • Analyze the geometry, kinematic evolution and structural features of natural (field and subsurface) fault-related folds from the north portion of the Iberian Peninsula (Cantabrian Mountains, Basque-Cantabrian Basin and Pyrenees) and other regions around the world
