Age constraints on the tectonothermal evolution of the Selwyn Zone, Eastern Fold Belt, Mount Isa Inlier

Rubenach, Michael J.; Foster, D.R.W.; Evins, P.M.; Blake, K.L.; Fanning, Christopher


The Selwyn Zone is characterized by multiple ductile deformation and metamorphic events. There is general consensus that early in the Isan Orogeny there were both extensional and thrust events that produced bedding-parallel foliation (Sbp). We propose that these were followed by the D1 event that resulted in a regional steep east-west foliation, and that the Snake Creek Anticline and the dominant S2a regional foliation formed as upright north-south structures. Local overturning of D2 structures...[Show more]
