Abstract The South China Craton consists of the Yangtze and Cathaysia blocks that were
welded together along the Jiangnan Fold Belt in the Neoproterozoic. The Neoproterozoic …

Abstract Series of trachytic rocks, containing significantly high Nb contents, were identified in
the Zhuxi region of South Qinling Orogenic Belt (SQB). An integrated investigation, mainly …

Abstract The composite Meghri–Ordubad and Bargushat plutons of the Zangezur–Ordubad
region in the southernmost Lesser Caucasus consist of successive Eocene to Pliocene …

Serpentinites in subduction zones are important fluid reservoirs for crust-mantle interaction
and arc magma formation. The serpentinite-derived fluids can carry fluid-mobile elements …

In recent years, the mélange model has been increasingly considered as an important way
to transfer slab components to arc sources in modern subduction zones. This model differs …

Abstract The East-Qinling pegmatite district located in the North Qinling terrane is the largest
one in the Qinling orogen, Central China. It is famous for its rare-element (REL) reserves, but …

Subduction of oceanic slabs can physically and chemically modify mantle wedges, but how
mantle wedges are temporally evolved is difficult to be constrained. In this study, we use in …

Primitive arc magmas in oceanic island arcs are probes of sub-arc magmatic processes and
are crucial for understanding oceanic subduction. We report data for an Early Paleozoic …

Adakitic rocks are often considered as a key to deciphering the genesis of Archean TTGs
and the early crustal growth. Granites from the Huichizi pluton in the North Qinling (NQ) unit …

Mafic arc igneous rocks with oceanic crust-derived fluids in their mantle sources generally
show heavy Mo isotope compositions. However, these rocks may exhibit variable Mo …
