“…Hardie's oceanic Mg/Ca model is further supported by synchronized transitions between MgSO 4 and KCl evaporites (Hardie, 1996), fluid inclusion data (Lowenstein et al, J. B. Ries: Effects of secular variation in seawater Mg/Ca on marine biocalcification 2837 , 2005Brennan and Lowenstein, 2002;Brennan, 2002;Horita et al, 2002;Brennan et al, 2004;Timofeeff et al, 2006), secular variation in the skeletal Mg/Ca ratio of rugose corals (Webb and Sorauf, 2002), echinoderms (Dickson, 2002(Dickson, , 2004Hasiuk and Lohmann, 2008), and abiogenic carbonates (Hasiuk and Lohmann, 2008); secular variation in the ratio of aragonite-to-calcite within bi-mineralic calcareous serpulid worm tubes (Railsback, 1993); secular variation in the Sr/Mg ratio of abiogenic marine carbonates (Cicero and Lohmann, 2001); the occurrence of higher seawater Sr/Ca ratios during predicted calcite sea intervals than during predicted aragonite sea intervals (Sr would be depleted in seawater during aragonite sea intervals because Sr is more readily incorporated in aragonite than in calcite; Steuber and Veizer, 2002); and secular variation in the Br concentration of marine halite (Siemann, 2003).…”

“…Phanerozoic (solid curve; Hardie, 1996;Demicco et al, 2005) and Precambrian (dashed curve; seawater Mg/Ca is calculated from hydrothermal brine-river water mixing models driven by rates of ocean crust production (Gaffin, 1987) and granite pluton data (Engel and Engel, 1970), respectively. Open circles correspond to Mg/Ca sw estimated from fluid inclusions in primary marine halite (Lowenstein et al, 2001Brennan and Lowenstein, 2002;Brennan, 2002;Horita et al, 2002;Brennan et al, 2004;Timofeeff et al, 2006). Horizontal line divides the calcite (Mg/Ca sw < 2) and aragonite -high Mg calcite (Mg/Ca sw > 2) nucleation fields in seawater at 25 • C (Leitmeier, 1910(Leitmeier, , 1915Lippman, 1960;Müller et al, 1972;Berner, 1975;Given and Wilkinson, 1985;Stanley and Hardie, 1999).…”

“…Evaporites were initially interpreted as marine in origin [23] but later as non-marine because subaerial features such as desiccation cracks, caliche, and anhydrite nodules were identified in the associated clastic redbeds [29]. More recently, correlation of anhydrites [23], sulfur isotope measurements of anhydrites [24], and fluid-inclusion analysis in primary chevron halites [31] show that the evaporites of the Maha Sarakham Formation are indeed marine in origin and formed when seawater flooded the Khorat Plateau. Siliciclastic redbeds represent continental deposits between marine incursions.…”
