Mineral chemical identification of assimilation in the formation of Cu-Ni related layered intrusion: A case study of Hongshishan mafic-ultra mafic intrusion in Beishan area, Xinjiang (NW China)
1 IntroductionMagmatic immiscibility and assimilation are the main factors controlling the sulfur saturation which is closely related to the formation of Cu-Ni ore deposit (e.g. Li et al., 2001; Naldrett, 2005). Immiscibility is rarely reserved because of covers from subsequent processes. On the other hand, records of assimilation could be tracked by petrological and geochemical observations. Abundant studies have documented whole-rock compositions (major, trace and isotope) are important references to distinguish assimilation and even its proportion (e.g. Sarkar et al., 2008; Stevenson et al., 2009). In current case study of Hongshishan intrusion, identification of assimilation from mineral chemistry is attemptly established integrating general indicators.
