“…While the concept that dolomite forms within sediments mediated by anaerobic microbial processes and their extracellular polymeric substances is widely acknowledged, another aspect should be taken into account: the site of dolomite formation may not always coincide with the location where the mineral is found due to relocation after precipitation. Several studies describe unlithified dolomite precipitation in warm, arid and hypersaline marine environments, like coastal sabkhas (Illing et al, 1965;Bontognali et al, 2010;Court et al, 2017), coastal lakes, such as Lagoa Vermelha in Brazil (Vasconcelos and McKenzie, 1997;van Lith et al, 2002;Sánchez-Román et al, 2009), and ephemeral lakes along the Coorong lagoon in southern Australia (von der Borch, 1976;Rosen et al, 1989;Warren, 1990;Wright and Wacey, 2005). Dolomite precipitation is further reported in endorheic hypersaline lakes, e.g., Qinghai Lake in Tibet (Deng et al, 2010), Lake Acıgöl (Turkey;Balci et al, 2016) and alkaline playa lakes such as Deep Springs Lake in California (Meister et al, 2011).…”
