“…6b) which supports a felsic composition crust. Petrography and mineralogy studies in the western part of the Khorat Plateau (Saminpanya et al, 2014) also support our result with the evidence that their source rocks are high in silica (SiO2 67-98 wt.%). The low Poisson's ratio of the KP-ICT is also about the same as the average value found in northern Vietnam (Bai et al, 2010;Nguyen et al, 2013) which is also described as being a felsic composition crust.…”

“…A three-stage model for describing an ore-forming fluid's evolution (based on a multiple-source theory) was introduced by Zhang Xiying et al (2015), which incorporated the influence of brine on diagenetic processes. While extensive research (Zhang et al, 2013;Saminpanya et al, 2014;Zhang Hua et al, 2015) has confirmed the veracity of multiple-source theory in explaining the origin of potash deposits, considerable difficulty remains in discriminating between terrigenous-sourced and deep hydrothermal-sourced ore-forming fluids.…”

The Khorat Plateau on the Indochina Terrane is known to have formed during the closure of the Tethys Ocean, although the origin of its potash mineral deposits is a topic of current debate. Data from a borehole on Savannakhet Basin is used in this study to re‐define the evaporation processes of the study area. Geochemical analyses of halite from various borehole‐derived evaporite strata have elucidated the fluid sources from which these ores formed. Measured δ11B indicated that ore deposits formed primarily due to evaporation of seawater, although non‐marine fluids affected the later stages of the evaporation process. Fluctuations in B and Br concentrations in carnallite‐ and sylvite‐rich strata indicate the influence of fresh water. Boron concentration in carnallite unit indicated the influence of hydrothermal fluids. From the relative timings of these various fluid influxes, the evolution of these evaporates can be divided into four stages: (1) an initial marine evaporation at the beginning of the deposit's formation, where seawater (and minor fresh water) trapped on the uplifted Khorat Plateau produced sediments and salts with Br contents lower than those of normal marine‐derived evaporites; (2) a transgression stage, where seawater recharged the basin; (3) a hydrothermal infiltration stage, which was coeval with the late Yanshan movement; and (4) a stage of fresh water supply, as recorded by fluctuations in B and Br contents, inferring intermittent fresh water influx into the basin. Thus, although evaporites on the Savannakhet Basin primarily formed via marine evaporation, they were also influenced to a significant degree by the addition of non–marine fresh water and hydrothermal fluids.

“…The major and trace element compositions of sediments have been widely used to infer the tectonic setting of ancient sedimentary basins (Bhatia, 1983;Taylor and McLennan, 1985;Bhatia and Crook, 1986;Saminpanya et al, 2014;Kassi et al, 2015), and on a SiO 2 vs. K 2 O/Na 2 O diagram the Shihuiding Formation sandstone data suggest deposition in a passive margin setting (Fig. 12a).…”

“…In addition to the major elements, immobile trace elements with stable geochemical characteristics (e.g., La, Th, Sc, and Zr) can be used to identify tectonic setting (Bhatia and Crook, 1986;Saminpanya et al, 2014;Kassi et al, 2015). On the La-Th-Sc diagram (Fig.…”
