“…Knowledge-driven techniques use mineral-system approaches (Barnicoat, 2007;McCuaig et al, 2010;Wyborn et al, 1994) to identify, spatially quantify and then combine the formation of interested type of mineral deposits. They include Boolean logic (Bonham-Carter et al, 1989;Mukhopadhyay et al, 2003), index overlay (Bonham-Carter et al, 1989;Carranza et al, 1999;Mukhopadhyay et al, 2003), fuzzy logic (An et al, 1991;Brown et al, 2000;Carranza and Hale, 2001a;Chung and Moon, 1990;D'Ercole et al, 2000;Karimi et al, 2008;Knox-Robinson, 2000;Lusty et al, 2012;Molan and Behnia, 2013;Nykänen et al, 2008), wildcat mapping (Carranza, 2010;Carranza and Hale, 2002b), spatial factor analysis (Grunsky and Agterberg, 1989), multiple criteria decision-making (Abedi et al, 2012b(Abedi et al, , 2012c(Abedi et al, , 2013a, interval valued fuzzy sets topsis (Rad and Busch, 2011), and outranking method (Abedi et al, 2013b). These methods are commonly used in situations where there are not enough known mineral deposits in a study area.…”
