“…Radtke and others (1972) reported that primary unoxidized Au ore hosted by the Silurian and Devonian Roberts Mountains Formation at the Carlin Au deposit contains, on average, 480 ppm As an approximate 50-fold increase over local background. In addition, Albino (1994) found that haloes of As and Hg extend 80 rn beyond Au-rnineralized rock that is between 380 and 500 rn below the surface at the Ren deposit ( fig. 2).…”

“…For example, Albino's (1994) evidence from detailed drill hole sampling indicated that gold-related anomalies do not extend from mineralization at depth to the surface, whereas spalding et al (2005) convincingly showed that gold and trace element soil anomalies are useful guides to exploration.

A near-vertical fracture set in Miocene Carlin Formation tuffaceous sediments occurs approximately 800 m above a deep Carlin-type gold ore zone of Eocene age at the ren property on the northern Carlin trend, Nevada. the fractures, 0.2 to 2 cm wide, are filled with brown montmorillonite clays and contain a distinctive Carlin-type geochemical assemblage including Au, As, sb, Hg, tl, and s. these young, in situ geochemical anomalies are thought to originate from a paleogeothermal event that may have been seismically triggered by Yellowstone plume bulge-relaxation dynamics. the passage of the plume immediately north of the Carlin trend would have provided increased heat flow, which, coupled with crustal extension, may have allowed metal-charged geothermal vapor to be released from depth. the hydrothermal remobilization filled dilational fractures in surficial units with vapor-phase alteration clays containing the geochemical signature of the deep gold ore zone. such fractures, if found in other areas of northern Nevada's great mineral trends, may provide important exploration guidance for deep ore systems.
