Abstract

Abstract

Xingzi metamorphic core complex" exposed in the Lushan mountain of northern Jiangxi Province is a typical Cordilleran-type metamorphic core complex so far discovered in southeastern China. Numerous pegmatites intruded in the structural weak zone were present in the core of "Xingzi metamorphic core complex", which is contemporaneous with the detachment fault. Zircon U-Pb dating age of the pegmatite is 130 Ma, representing the uplift age of the complex, which is supported by other geological evidences. The possible spatial and temporal links, furthermore, between the complex formation and contemporary extensive Late Mesozoic magmatism in southeastern China are discussed in this paper.
- uplift age,
