“…However, Si-poor and aluminous amphibole phases (~3.5-3.7 Al apfu and ~5.8-5.5 Si apfu) have been occasionally reported from retrograde eclogites in Alps (e.g., Mogessie et al, 1986;Messiga et al, 1991;Poli, 1991) and Himalaya (e.g., Palin et al, 2014;O'Brien, 2019). They sometimes occur as pseudomorphs after garnet also in coesite eclogites from several localities of the Sulu ultrahigh-pressure (UHP) metamorphic belt, China, such as Rongcheng, Yangkou, and Donghai areas (~3.5 Al apfu and ~5.5 Si apfu: Enami et al, 1993;Yang, 2004;Liu et al, 2009;Yamasaki et al, 2018).…”
