The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.

The Prydz Belt occurs in the Prydz Bay and Denman Glacier, and is located in the interior of a previously proclaimed unified East Gondwana. The absence of subduction-related rocks, such as ophiolite suite, arc accretionary complex and high-pressure blueschist and eclogite, resulted in the argument that the Prydz Belt represents whether a collisional zone or an intraplate reworking belt.
