“…Magnetite magnetofossils, often partially oxidized to maghemite, have been found as a major magnetic component of lacustrine (Dearing et al, 1998;Kim et al, 2005;Oldfield et al, 2003;Pan et al, 2005;Peck and King, ;Snowball, 1994), microbial mat , hemipelagic (DinaresTurell et al, 2003;Housen and Moskowitz, 2006;Stolz et al, 1986), pelagic (Hesse, 1994;Hilgenfeldt, 2000;Lean and McCave, 1998;Petersen et al, 1986;Yamazaki and Ioka, 1997;Yamazaki et al, 1991) and carbonate platform (Maloof et al, 2007;McNeill, 1990;McNeill et al, 1988;Sakai and Jige, 2006) sediments. Greigite magnetofossils have not yet been identified in Quaternary sediments.…”
