Mineralogy and geochemistry of claystones from the Guadalupian–Lopingian boundary at Penglaitan, South China: Insights into the pre-Lopingian geological events

First Identification of Late Permian Nb‐Enriched Basalts in Ailaoshan Region (SW Yunnan, China): Contribution From Emeishan Plume to Subduction of Eastern Paleotethys

“…Previous studies on the Permian‐Middle Triassic magmatic and clastic rocks in SW China suggested that the Ailaoshan Ocean subducted eastward beneath the western South China Block during the Permian‐Middle Triassic (Hou et al, ; C. Huang, ; Qin et al, ; Z. L. Wang et al, ; M. Wang, Zhong, et al, ; D. Xu et al, , ; J. Yang et al, ; Z. Yang & He, ; Y. Zhang et al, ; Y.‐T. Zhong et al, ). For example, extensive arc‐type volcanic rocks were reported in southwestern China, such as the Late Permian (ca.…”

Cryptic sediment-hosted critical element mineralization from eastern Yunnan Province, southwestern China: Mineralogy, geochemistry, relationship to Emeishan alkaline magmatism and possible origin

“…13). Since ELIP silicic rocks (metaluminous, peraluminous and peralkaline) are fractional products of high-Ti mafic magmas (Shellnutt, 2014;Xu et al, 2010Xu et al, , 2013 and the ELIP metaluminous and peraluminous silicic rocks were contaminated by crustal materials (Shellnutt, 2014), the series from "high-Ti basalts to peralkaline silicic rocks" may be representative of ELIP magmatic evolution of waning stage.…”

CA-TIMS zircon U–Pb dating of felsic ignimbrite from the Binchuan section: Implications for the termination age of Emeishan large igneous province

“…Present day Th/U ratio is calculated from radiogenic Zhou et al (2002Zhou et al ( , 2006Zhou et al ( , 2008, Fan et al (2004), Zhong and Zhu (2006), He et al (2007), Luo et al (2007), Shellnutt and Zhou (2007), Zhong et al (2007), Xu et al (2008, Shellnutt et al (2012) Ar ages underestimate the emplacement age of the igneous rocks in the Emeishan LIP. tuffs or ashes, and are thus not suitable for the age determination of the G-L boundary (Zhong et al, 2013). …”
