Carlin-style gold province linked to the extinct Emeishan plume
Earth and Planetary Science Letters, 2020Abstract Carlin-style gold deposits constitute one of the most important types of Au resources in the world. Previous studies on these deposits correlated the source of Au with metal-enriched sedimentary formations or metasomatized subcontinental lithospheric mantle (SCLM) associated with oceanic subduction.

Tectonophysics, 2018
Abstract The Emeishan large igneous province (ELIP) is widely considered to be a consequence of a mantle plume. The supporting evidence includes rapid emplacement, voluminous flood basalt eruptions, and high mantle potential temperature estimates. Several studies have suggested that there was surface uplift prior to the eruption of the Emeishan flood

Early Wuchiapingian cooling linked to Emeishan basaltic weathering?
Earth and Planetary Science Letters, 2018Abstract The last glaciation during the late Paleozoic ice age commenced at around the Guadalupian–Lopingian (G–L) boundary and is synchronous with the emplacement of the Emeishan large igneous province. Using CA-TIMS zircon U–Pb dating, we obtained an age of 259.51 ± 0.21 Ma for the uppermost tuff from the Puan volcanic sequence in the eastern ...

Thermal convection dolomitization induced by the Emeishan Large Igneous Province
Marine and Petroleum Geology, 2020Abstract The mechanism of dolomitization has long been debated due to complex sedimentary and diagenetic conditions. Large-scale dolomite bodies were recently discovered in the Permian Cisuralian Qixia Formation (284–273 Ma) in the northwestern Sichuan Basin, providing an opportunity to understand the dolomitization associated with the Emeishan Large

Abstract New petrographic, major element, trace element and isotopic data (Sr and Nd) for 17 Emeishan basalts from the Lijiang-Shangri-La area of SW China are integrated with published data comprising ~ 300 mafic rocks from the Emeishan large igneous province (LIP) to create a comprehensive model for this LIP event.

Madouzi-type (nodular) sedimentary copper deposit associated with the Emeishan basalt
Science China Earth Sciences, 2011Ore minerals in the sedimentary-type Cu deposits in the Xuanwei Formation overlying the Emeishan basalt are dominated by copper sulfides and native copper. As the ores mostly exhibit concretionary structure, previous researchers named them the “Madouzi-type Copper Deposit”.

Role of slab-derived fluids in the Emeishan Large Province
Geological Society of America BulletinAbstract The role of fluids in the formation of large igneous provinces (LIPs) remains a topic of debate. The Emeishan Large Igneous Province (ELIP) in southwestern China, with a large volume of mafic intrusive and extrusive suites, provides an ideal window to explore this enigma.

Stratigraphic records of the dynamic uplift of the Emeishan large igneous province
International Geology Review, 2015AbstractFluid dynamical and numerical modelling predicts a large-scale regional domal uplift prior to basalt eruptions in large igneous provinces, which can be readily measured when a plume head rises below a shallow marine sedimentary basin. Research on the sedimentology, biostratigraphy, and isotopic chronology of the Emeishan large igneous province ...

Magnetostratigraphic investigations on an Emeishan basalt section in western Guizhou province, China
Earth and Planetary Science Letters, 1998Abstract A magnetostratigraphic investigation has been conducted on a late Permian Emeishan basalt section at Duge in western Guizhou province, China. The characteristic remanent magnetization (ChRM) directions resolved at high temperatures from the basalts pass the fold test with dual polarity and define a normal magnetozone of five sixths of the ...
