“…Some hematite inclusions with a similar appearance as in the RLS have been found in Tanzania (Koivula and Tannous, 2003) and North Carolina, USA (Challener et al, 2017). The morphology of the iron oxide inclusion seems to be correlated with the composition and structure of the host feldspar, with acicular inclusions found only in intermediate to calcic plagioclase (Armbrustmacher and Banks, 1974;Nienaber-Roberts, 1986;Sobolev, 1990;Wenk et al, 2011;Ageeva et al, 2020;Jin et al, 2021;Bian et al, 2021) and flaky inclusions mostly in sodic plagioclase and alkali feldspar (Boone, 1969;Copley and Gay, 1979;Challener et al, 2017;Liu et al, 2018).…”
