Kimberlite bodies can be identified at ground surface using soil geochemistry where 90 m of glacial sediment overlies a kimberlite. This is based on variations in element concentrations of pathfinder elements such as Ni, Mg, Co, K, and total REEs over versus off a kimberlite. 

The Gore Amplified Geochemical lmagingSM technique, like soil geochemistry, shows anomalous concentrations of sulfides and hydrocarbons in soils over the kimberlite.

Soil geochemistry is widely applied in mineral exploration, and with advancing knowledge of speciation and residence phases of trace elements in soils, a variety of partial and selective extractions for chemical analysis have been developed over the past decades. Each of these methods has been designed to target and dissolve only those elements that are adsorbed onto labile phases in soil, from carrier fluids and gases that transported them from a deposit to the surface (e.g. Hall etal. 1996).

Mineralogy and soil geochemistry along the W-E transect reflect both the influence of soil parent materials and effect of hemispheric climate gradients. The quartz dilution effect described by Bern (2009) dominates the distribution of a number of elements Al is given as an example in Figure 2.

Although much research at both UNB (University of New Brunswick) and UNSW (University of New South Wales) was on drainage and soils geochemistry, this paper will deal mostly with rock geochemistry and anomaly formation. 

At the White Lake Cu-Zn sulfide deposit (near Flin Flon, Manitoba) no geochemical signature had been obtained from conventional soil geochemistry. Where the deposit is overlain by 23m of barren rock and 8m of glacial overburden including an upper 1m of impermeable varved clay, a strong characteristic rabbit-ear H anomaly clearly indicates the location of the orebody, as predicted by the electrochemical model (Govett 1976).

In the 1960s and 1970s the use of soil geochemistry in mineral exploration led to the discovery of the now commonly observed twin-peak or rabbit-ear geochemical anomaly (Govett 1976). From the time rabbit-ear anomalies were first described they were attributed to electrochemical processes but the theory proposed at that time could only...

Bendigo is a classic example of a low-sulphide gold-quartz deposit located in a folded sequence of sandstone and shale of the Cambrian-Ordovician age (Ramsay et al. 1998 Goldberg et al. 2007).

Patterson et al. (2001) examined the uptake of F by Wyoming big sagebrush and western wheatgrass in the area where the PL and TP transects were made, and reported very little or no translocation of F from roots to plant leaves. The solubility estimates, combined with the observations of plant uptake, indicate that precipitation of CaF2 in these soils may limit root uptake of F. Therefore, the soil geochemistry supports the Patterson (2002) findings of F plant uptake via stomatal entry.
