Apparent Polar Wander Path from the Tarim Block in China

The apparent polar wander (APW) path from the Tarim block consists of palaeo-magnetic poles ofDevonian (λ=16°N, ψ= 165° E. A_(95)=4°). Late Carboniferous (λ=41° N, ψ=160° E, A_(95)=4°).Permian (λ=61°N, ψ=177° E. A_(95)=9°). Early Triassic (λ=69° N. ψ=183° E. A_(95)=11°) andJurassic/Cretaceous (λ=65° N, ψ=214° E. A_(95)=6°) times. On the basis of this APW path, it is con-cluded that the Tarim block was subducted beneath the Kazakstan plate between Devonian and Permiantimes. The Tarim, North China and South China blocks were sutured between the Early Triassic and EarlyCretaceous. Tarim had moved eastward some 2000 km relative to Siberia since the Cretaceous.

Apparent Polar Wander Path from the Tarim Block in China

Abstract The apparent polar wander (APW) path from the Tarim block consists of palaeo- magnetic poles of Devonian (λ = 16 ° N, φ= 165 ° E, A₉₅ = 4 °), Late Carboniferous (A = 41 ° N, φ= 160 ° E, A95 = 4 °), Permian u = 61 ° N, φ=177° E, A95 = 9°), Early Triassic U = 69° N, φ=183° E, A⁹⁵=ll °) and Jurassic/ Cretaceous (A = 65 ° N, (A = 214 ° E, A⁹⁵ = 6 °) times. On the basis of this APW path, it is concluded that the Tarim block was subducted beneath the Kazakstan plate between Devonian and Permian times. The Tarim, North China and South China blocks were sutured between the Early Triassic and Early Cretaceous. Tarim had moved eastward some 2000 km relative to Siberia since the Cretaceous.
