Abstract
The Tarim Large Igneous Province (Tarim LIP) agrees well with the mantle plume model in terms of its tempo-spatial distribution of Permian igneous rocks. The domal uplift of the crust before eruption, widespread dike swarms and occurrence of picrate also support the plume involvement in the origin of the Tarim LIP. The interrelationship between the Tarim LIP and adjacent Permian magmatisms, like the Tianshan Group, the Emeishan LIP and Siberian Traps, indicates that the Tarim LIP is geologically independent from these igneous provinces. The geochemical signatures and tempo-spatial distribution of the Tarim LIP appeals to a two-stage melting model for Permian Tarim magmatism. The geodynamic settings of the Tarim Block in the Early Permian lead to the plume-lithosphere interaction for the petrogenesis of the Tarim LIP.
