Geophysical evidence for 'thick-skinned' crustal deformation in central Australia

Geophysical evidence for 'thick-skinned' crustal deformation in central Australia

Until now there has been no clear evidence from deep seismic reflection profiles of crustal faults that displace the Moho. New data from central Australia show such structure in a region characterized by large thrust structures, large gravity anomalies and abrupt changes in teleseismic travel time....

Zusammenfassung:Until now there has been no clear evidence from deep seismic reflection profiles of crustal faults that displace the Moho. New data from central Australia show such structure in a region characterized by large thrust structures, large gravity anomalies and abrupt changes in teleseismic travel time. The geological and geophysical evidence leads to a model of thick-skinned crustal deformation.
