In this study, we compared traditional lithochemical sample media (soil) with hydrochemical (groundwater), biogeochemical (plant matter of mulga and spinifex), and other near-surface sample media (ferro-manganese crust), in a case study applied to mineral exploration in weathered terrain, through the critical zone at the fault-hosted Prairie and Wolf Zn–Pb (Ag) deposits in Western Australia. We used multi-element geochemistry analyses to spatially identify geochemical anomalies in samples over known mineralization, and investigated metal dispersion processes. In all near-surface sample media, high concentrations of the metals of interest (Zn, Pb, Ag) coincided with samples proximal to the mineralization at depth. However, the lateral dispersion of these elements differed from regional (several km; groundwater) to local (several 100′s of meters; solid sample media) scales. Zinc in spinifex leaves over the Prairie and Wolf deposits exceeded the total concentrations in all other sample media, while the metal concentrations in mulga phyllodes were not as pronounced, except for Ag, which exceeded the concentrations in all other sample media. These observations indicate potential preferential metal-specific uptake by different media. Pathfinder elements in vegetation and groundwater samples also indicated the Prairie Downs fault zone at the regional (groundwater) and local (vegetation) scale, and are, therefore, potentially useful tools to trace fault systems that host structurally controlled, hydrothermal Zn–Pb mineralization.

Abstract The geochemical analysis of trace elements in rutile (e.g., Pb, U, and Zr) is routinely used to extract information on the nature and timing of geological events. However, the mobility of trace elements can affect age and temperature determinations, with the controlling mechanisms for mobility still debated. To further this debate, we use laser-ablation–inductively coupled plasma–mass spectrometry and atom probe tomography to characterize the micro- to nanoscale distribution of trace elements in rutile sourced from the Capricorn orogen, Western Australia. At the >20 µm scale, there is no significant trace-element variation in single grains, and a concordant U-Pb crystallization age of 1872 ± 6 Ma (2σ) shows no evidence of isotopic disturbance. At the nanoscale, clusters as much as 20 nm in size and enriched in trace elements (Al, Cr, Pb, and V) are observed. The 207Pb/206Pb ratio of 0.176 ± 0.040 (2σ) obtained from clusters indicates that they formed after crystallization, potentially during regional metamorphism. We interpret the clusters to have formed by the entrapment of mobile trace elements in transient sites of radiation damage during upper amphibolite facies metamorphism. The entrapment would affect the activation energy for volume diffusion of elements present in the cluster. The low number and density of clusters provides constraints on the time over which clusters formed, indicating that peak metamorphic temperatures are short-lived, <10 m.y. events. Our results indicate that the use of trace elements to estimate volume diffusion in rutile is more complex than assuming a homogeneous medium.

The emergence of the concept of a “mineral system” has changed the way regional-scale mineral prospectivity is assessed. Geographically widespread data sets and deep-penetrating geophysical methods are required to map the various components of the mineral system, which may encompass areas of perhaps thousands of square kilometers and extend to mantle depths. Key mineral system components that can be detected in this fashion include deep-penetrating faults and the suture zones between major geologic blocks, which are important controls on the movement of metal-carrying magmas and brines in a variety of mineral systems. Two case studies from mineralized terrains in Western Australia illustrate the use of deep-penetrating geophysical methods in mineral exploration. Magnetotelluric (MT) data from a 300-km-long traverse in the Archean Yilgarn Craton map numerous steeply dipping conductive zones, which coincide with linear anomalies in potential field data and are interpreted as deep-penetrating faults. Also, lateral changes in crustal and upper mantle resistivity structure suggest the juxtaposition of two, or perhaps three, different major crustal blocks with intervening suture zones. Teleseismic data from a 250-km-long traverse in the Proterozoic Capricorn Orogen provide information on deep crustal structure and composition. Interpretation in association with deep seismic reflection data allows previously unrecognized suture zones to be recognized in the deep crust and under thick cover. Passive seismic and MT methods represent a comparatively cost effective way to identify key mineral system indicators of regional prospectivity, even in the geologically complex terrains of Western Australia.
