Understanding the compositional heterogeneity of the deep mantle requires identifying the nature of recycled crustal materials in the sources of mantle-plume-related magmas. However, it is still unclear whether or not the deep mantle contains recycled carbonates from the Earth’s surface. In this study, we present comprehensive data on whole-rock hi...

The North China Craton (NCC) is one of the most complex cratons in the world. It underwent a series of tectonothermal events during the Neoarchean–Paleoproterozoic. The petrogenesis of potassic granitoids, the timing, and the style of Archean crustal growth are still debated. Systematic field and petrological stdudies on the potassic meta-granites...

The genesis of peralkaline granites (with molar (Na + K)/Al > 1) remains a conundrum, particularly their emplacement accompanied by contemporaneous calc-alkaline rhyolites rather than peralkaline rocks. In this study we present a petrogenetic comparison of calc-alkaline rhyolites (296–293 Ma) and subsequent peralkaline granites (291 Ma) in Baiyinwu...

There are several different models for the origin of syenites, but the role of magma mixing in the formation of syenites remains unclear. The Wulingshan alkaline complex in the northern North China Craton consists mainly of porphyritic syenite and syenite with abundant enclaves. These enclaves may provide new insights into the petrogenesis of syeni...

Thickened crust is of great significance for tectonic evolution and mineralization and generally occurs in collisional orogenic belts. Whether accretionary orogenic belts, such as the Central Asian Orogenic Belt (CAOB), are able to create remarkably thickened crusts and what the mechanism is, remain to be determined. In the southwestern of CAOB, th...
