Tectónica da região de Sintra
Kullberg, M. C.; Kullberg, J. C.Photo-interpretation of aerial stereopairs of the Sintra region on the approx. 1/32 000 scale together with field work allowed the production of the present Tectonic Map of the Sintra region. It is now possible to separate structures which resulted from two different tectonic events: one, corresponding to the intrusion of the Late Cretaceous Sintra igneous diapir, and the other the Miocene compressive event, th...
Tectónica da cadeia da Arrábida
Kullberg, M. C.; Kullberg, J. C.; Terrinha, P.Geociências, Museu Nac. Hist. Nat. Univ. Lisboa, nº 2, 35-84 ; A tectonic map of the Arrábida fold and thrust belt ( 30 km x 6 km) based on aerial-photo interpretation and field work is presented together with geological cross-sections constrained by seismic and gravimetric data, one restored section and kinematic models for the evolution of the Sesimbra salt-wall and the Palmela gravitational slide. Two rift...
Interpretação tectónica de um conjunto de lineamentos WNW-ESE observados em ima...
Kullberg, M. C.; Kullberg, J. C.The existence of satellite images ofthe West Iberian Margin allowed comparative study of images as a tool applied to structural geology. Interpretation of LANDSAT images of the Lusitanian Basin domain showed the existence of a not previously described WNW-ESE trending set oflineaments. These lineaments are persistent and only observable on small scale images (e.g. approx. 11200000 and 11500 000) with various ra...
Geodynamics of the eastern sector of the Arrábida chain (W Portugal)
Kullberg, M. C.; Kullberg, J. C.; Ribeiro, A.; Phipps, S.N.º4, p.263-267 ; The Arrábida chain - located in the southern segment of the Lusitanian basin - is a S-wards directed fold and thrust belt of Miocene age of deformation. ENE-WSW striking frontal ramps and associated folds are connected to sinistral NNE-SSW and N-S striking lateral ramps, that show left-lateral and SE-wards reverse movements. Both frontal and oblique ramps form imbricate duplexes. Constriction...
