... using new laser ablation ICP-MS trace element data for magnetite, ilmenite, and clinopyroxene from the Panzhihua layered intrusion in the Emeishan large igneous province, SW China. The cumulus minerals display strong Ni, Co, and Cr depletions, indicative of parental magmas low in concentration...

...; Zhou, 2007 ). Within the Panxi region (Panzhihua-Xi Chang) of the Emeishan large igneous province, spatially and temporally associated with the peralkaline granitic rocks, are layered gabbroic intrusions which host world-class orthomagmatic Fe-Ti-V oxide deposits ( Zhou et al. , 2005...

... Panzhihua Fe-Ti-V oxide deposit described previously by others, mafic silicates in the Hongge deposit have much higher MgO contents than those in other oxide deposits associated with large layered intrusions in the world. This highlights the importance of relatively primitive parental magma becoming...

... deployed temporary seismic array. The results show that low‐velocity anomaly is imaged mainly in the eastern and southeastern Tibetan plateau (except the southern Panzhihua area) above 200 km depth in the upper mantle, whereas a high‐velocity anomaly exists to its east especially beneath the Sichuan basin...

... in the central part of the ~260 Ma Emeishan large igneous province is the most important Fe-Ti-V metallogenic district in China. Fe-Ti oxide-bearing, mafic-ultramafic layered intrusions, including Panzhihua, Hongge, Baima, Xinjie, and Taihe, are exposed along several major N-S trending faults in the Panxi region...

...XUE-MING TENG; M. SANTOSH; LI TANG Abstract – The North China Craton (NCC) is one of the classic examples of decratonization through extensive lithospheric destruction during Mesozoic time. Among the various pulses of magmatism associated with cratonic erosion are the rare mafic intrusions...

... in the Panzhihua Province of China ( Wang & Zhou, 2013 ; Zhou et al. , 2013 ). The interstitial microstructures including symplectites and coronas in these studies are regarded as important evidence for silicate-melt immiscibility during the formation of the mafic intrusions ( Holness et al. , 2011...

...Chang-Ming Xing; Christina Yan Wang Abstract Cathodoluminescence (CL) and trace element analyses were performed for fluorapatite from the gabbro and Fe-Ti oxide ores in the upper zone of the Hongge Fe-Ti oxide-bearing, mafic-ultramafic layered intrusion in SW China. The fluorapatite is closely...

Ripley; Chao Li Abstract The Lengshuiqing magmatic Ni-Cu ore deposit is hosted in four small mid-Neoproterozoic mafic-ultramafic intrusions in the western margin of the Yangtze craton in China. The ore-bearing intrusions...

... reserves ( Song et al., 2018 ) occur as magmatic Fe-Ti-V oxide deposits hosted by several adjacent mafic-ultramafic intrusions in the Panzhihua-Xichang (Pan-Xi) district of southwest China ( Fig. 1 ). The mineralized intrusions are part of the Emeishan large igneous province (LIP) and are genetically...

..., the internal model and the external model, have been formulated to constrain the paleogeographic position of the South China block in Rodinia. In this study, we examined 17 representative samples from three intrusions (Kuchahe, Leidashu, and Qizanmi) within the Ailao Shan–Red River belt, located...

... elsewhere ( Chen et al . 2013 ). The samples were collected from the Fe-Ti-P-rich oxide ore bodies. The Panzhihua and Xinjie layered intrusions are part of the ∼260 Ma Emeishan large igneous province in SW China. The Panzhihua intrusion, which is one of the most important Fe-Ti-V-rich oxide deposits...

... intrusions were also emplaced. In most localities, the silicic plutons and mafic-ultramafic intrusions do not appear to be petrogenetically related and are likely derived from different sources. The Attwoods Brook gabbronorite of SW Nova Scotia yielded an in situ zircon weighted-mean 206 Pb– 238 U age...
