A Changhsingian (Late Permian) brachiopod fauna from Son La, northwest Vietnam
Section snippets
Introduction and stratigraphy
This paper describes a small brachiopod fauna collected by the senior author during a field excursion to the Son La area about 250 km northwest of Hanoi (Fig. 1) in November 1995. The excursion was organised by the Vietnam National Committee for IGCP and the Geological Survey of Vietnam as part of the International Symposium on the Geology of Southeast Asia and adjacent Areas held in Hanoi between 1–9 November 1995.
The Permian System is sporadically distributed in Vietnam (Fig. 1). On the basis
Correlation and age of the brachiopod fauna
The brachiopods described in this paper appear to represent only a small portion of a potentially large and diverse fauna. Collecting of the fauna in the field was not exhaustive as time available was rather limited during the excursion. Nevertheless, in view of the species identified herein and their relationships with species from adjacent regions, especially South China and northwest Thailand (see correlations discussed below), the brachiopod assemblage clearly demonstrates a significant

The Indosinian orogeny: A perspective from sedimentary archives of north Vietnam
2018, Journal of Asian Earth SciencesCitation Excerpt :The basement of the Song Da Basin is heterogeneous and includes various Archean (Lan et al., 2001) to Permian (e.g., Tri and Khuc, 2011; Thanh and Khuc, 2012) metamorphic and sedimentary rocks. The Song Da Basin is classically interpreted as a continental rift, sometimes referred to as the Song Da – Tu Le Rift (e.g., Shi and Shen , 1998; Glotov et al., 2001; Balykin et al., 2010; Anh et al., 2011; Tri and Khuc, 2011; Metcalfe, 2012; Hieu et al., 2013, 2017; Tran et al., 2015). The extension of the lithosphere associated with the rift formation has been proposed to evolve up to the formation of an oceanic lithosphere within the Song Da Basin (Liu et al., 2012).
Changhsingian (Late Permian) conodonts from Son La, northwest Vietnam and their stratigraphic and tectonic implications
2012, Journal of Asian Earth SciencesCitation Excerpt :The limestone has yielded a varied invertebrate fauna including forams, rugose and tabulate corals, bivalves, gastropods, rare brachiopods and calcareous algae (Dzanh and Tinh, 1995). The presence of the fusulines Codonofusiella sp., Nankinella inflata (Colani), C. parva (Colani), and P. prisca (Deprat), and corals Waagenophyllum pulchrum Hamada, W. simplex Wu) suggest a Changhsingian age (Shi and Shen, 1998) based on comparisons with South China. Shi and Shen (1998) described eight brachiopod species from shales and siltstones approximately 60 m below the top of the Yenduyet Formation above the limestone unit and in the same stratigraphic section on National Highway 6 discussed here.
