Geology, Geochronology, and Hf Isotopic Composition of the Pha Lek Fe Deposit, Northern Laos: Implications for Early Permian Subduction-Related Skarn Fe Mineralization in the Truong Son Belt

Detrital Zircon U‐Pb Age Distribution and Hf Isotopic Constraints From the Terrigenous Sediments of the Song Chay Suture Zone (NE Vietnam) and Their Paleogeographic Implications on the Eastern Paleo‐Tethys Evolution

“…Furthermore, the magmatic rocks with ages ranging from 310 to 245 Ma, interpreted as arc‐related rocks have been reported in the Western Ailaoshan and Sam Nua‐Truong Son belts (Figure 1; e.g., Fan et al., 2010; Hieu, Dung, et al., 2016; Hoa et al., 2008; Hou et al., 2019; Jiang et al., 2020; Kamvong et al., 2014; Lai, Meffre, Crawford, Zaw, Halpin, et al., 2014; Y. Li, 2012; Qian et al., 2019; X. Wang, Cao, et al., 2018). In contrast to the widespread Late Permian‐Middle Triassic magmatism, the distribution of Late Carboniferous‐Middle Permian magmatism is relatively limited in this magmatic belt (Hou et al., 2019). It seems that the magmatic arc was not well developed during the Late Carboniferous‐Middle Permian.…”

Detrital zircon U Pb age distributions and Hf isotopic constraints of the Ailaoshan-Song Ma Suture Zone and their paleogeographic implications for the Eastern Paleo-Tethys evolution

“…The achieved detrital zircon age distribution, and the corresponding in-situ Hf isotopic recorder allow us to discuss the provenances of the materials involved in the tectonic processes during the subduction and collision. Our new data suggests a complicated source of Lepvrier et al, 2008;Liu et al, 2012;Kamvong et al, 2014;Qian et al, 2019;Hou et al, 2019). At the north of Laos, the Sam Nua zone consists of Permian to Early Triassic volcanic and volcanic-clastic sedimentary series.…”

“…indicated the early stage of the magmatism and were often interpreted as typical for the subduction process (the A1 in Fig. 16; Hoa et al, 2008;Fan et al, 2010;Li, 2012;Kamvong et al, 2014;Lai et al, 2014aLai et al, , 2014bHieu et al, 2016;Wang et al, 2016bHou et al, 2019;Qian et al, 2019;Jiang et al, 2020). During this time, along the Song Chay segment, the magmatic arc was less developed, and the SCB (as the passive margin) acted as the main provenance of sediments in the mélange (Figs.…”
