Geochemical characteristics of halogen-bearing hastingsite, scapolite and phlogopite from the Sangan iron skarn deposits, northeastern Iran.

Mineralogical and sulfur isotopic evidence for the incursion of evaporites in the Jinshandian skarn Fe deposit, Edong district, Eastern China

“…Cl content of scapolite at Jinshandian overlaps with those of metamorphic rocks and different metal deposits which have been influenced by the incursion of evaporites, and is higher than those rocks and deposits without incursion of evaporites ( Fig. 7a and b; Appendix Table A1) (Ekströim, 1972;Mora and Valley, 1989;Moecher and Essene, 1991;Oliver et al, 1992;Ross, 1993;Buick and Cartwright, 1994;Pan et al, 1994;Boomeri et al, 1997;Frietsch et al, 1997;Kullerud and Erambert, 1999;Johnson, 2000;Faryad, 2002;Pan and Dong, 2003;Satish-Kumar et al, 2006;Douglas, 2011;Feneyrol et al, 2012).…”

“…(Hou et al, 2004) are also shown for comparison. Mora and Valley, 1989;Moecher and Essene, 1991;Oliver et al, 1992;Buick and Cartwright, 1994;Kullerud and Erambert, 1999;Faryad, 2002;Satish-Kumar et al, 2006;Feneyrol et al, 2012; data for deposits are from Ekströim, 1972;Ross, 1993;Pan et al, 1994;Boomeri et al, 1997;Frietsch et al, 1997;Johnson, 2000;Pan and Dong, 2003;Douglas, 2011).…”

“…11), higher than that of skarn Fe deposit ($50 wt.%, Zhao et al, 1990;Meinert et al, 2005). Although this value is very unrealistic, it is still useful for a qualitative estimation of salinity of the fluid and fluid evolution processes (Boomeri et al, 1997;Satish-Kumar et al, 2006;Li et al, 2015). The high salinity fluid probably originated from Cl-rich hydrothermal fluid in magma or from evaporites in the sediments.…”
