摘要: Abstract Extensive regional mapping of the stratigraphic sequence throughout Kalgoorlie - Kambalda greenstone belt in Western Australia has outlined geometry early subhorizontal thrust faults. These thrusts stacked and repeated stratigraphy to form a major duplex south Kambalda. The roof becomes flat north at Kalgoorlie. Later transpressional deformation (F2 upright folds, D3 sinistral shear zones folding) rotated displaced D1 thrusts. Both sub-horizontal subsequent transpression indicate that compressional tectonics, rather than vertical tectonics involving solid-state granitoid diapirs, were crucial development this granite-greenstone terrain.
