“…The mineralogy of sandstones infers the type of source rock and provides insights into the palaeotectonic and palaeoclimatic conditions (Dickinson & Suczek, 1979; Dickinson et al, 1983; Garzanti, 2016, 2019; Suttner & Dutta, 1986; Suttner et al, 1981). The varietal mineral chemistry of highly stable rutile and tourmaline grains in quartzose sandstones is particularly useful for tracking the source rocks (Chaudhuri, Banerjee, Prabhakar, et al, 2020; Henry & Guidotti, 1985; Meinhold, 2010; Rajak et al, 2022; Triebold et al, 2007, 2012; Zack et al, 2004). The whole‐rock chemical composition of fine clastic sediments associated with quartzose sandstones is particularly useful for inferring source rock characteristics, palaeoweathering and palaeoclimatic conditions (Armstrong‐Altrin et al, 2021, 2022; Bhatia, 1983; Chaudhuri, Banerjee, & Chauhan, 2020; Condie, 1991; Critelli et al, 2008; Hayashi et al, 1997; Le Bas et al, 1986; McLennan & Taylor, 1991; Roser & Korsch, 1988; Suttner & Dutta, 1986; Taylor & McLennan, 1985).…”
