North-central Nevada contains a large amount of gold in a variety of deposit types (Hofstra, 2002), and the origin of that gold (such as in Carlin-type deposits) is a much debated subject (Hofstra and others, 2003; Wallace and others, 2004). Major deposits occur in linear belts (fig. 1) that have long been believed to be controlled by the underlying crust and large tectonically controlled structures (Hofstra and Wallace, 2006).
