Accordingly, it is valid to claim the joint onset of micro-reaction technology in 1995 and to try to name those who were the pathfinders in this development (see, e.g., [3] for a description of such an opinion). Regarding the birth of micro-reaction...

New exploration techniques, and new reference materials in support of them, were needed. One major change was in the use of ore pathfinder elements, rather than the ore elements themselves, for exploration purposes. For example, instead of analyzing samples for the primary Au ore element, samples were analyzed for As, Hg, and W pathfinders that pointed to hidden gold deposits. The pathfinder elements occur in association with ore veins, but have a much broader spread than the mineralized area itself. However, measurement of the pathfinder elements requires methods with better detection limits than were needed in earlier exploration programs, as the pathfinders typically are not as enriched as the ore elements, in comparison to baseline crustal levels. 

Also consider the use of NIST sediments 1646, 2704, and soils 2709-2711 in exploration geochemistry. These samples were certified largely in view of the demand for samples to support monitoring of toxic elements in environmental samples. However, many of the elements certified overlap either the list of primary ore elements or the list of pathfinder elements. Thus, these samples may legitimately be used in a very different application than the one that prompted certification. The sample matrix is ideal for the alternative application, and so is the suite of certified elements.

If the government s Pathfinder programme is a success, the problem of insufficient therapists may be solved. But what do we do in the meantime People who are depressed cannot wait until the year 2015 for help. Fortunately, there are some low-cost alternatives that are available right now. These are treatment approaches that are sometimes used in conjunction with psychotherapy, but can also be used as stand-alone treatments. Let us take a look at them. 

As a starting point for reaction optimization, Biotage offers a microwave reaction database (Emrys PathFinder) with ca. 4000 validated entries for microwave chemistry performed with Biotage single-mode instruments.

A strong positive correlation exists between Cu, Ag, Co, Au, W, and Se in the B and C horizon soil and suggests that these elements are geochemical pathfinders for sulfide mineralization at the Shiko Lake mineral occurrence. Glacial dispersal of Cu and Co in C horizon soil samples is characterized by the shape of geochemical profiles. These typically... 

The partial leach results from soil samples identify the location of the buried Honerat kimberlite. The depletion of Ni, Mg, Co, K, and total REEs in C-horizon soils over the Honorat kimberlite suggests that numerous kimberlite pathfinder elements are not adsorbed on to soil particles. Instead, they are remaining in the dissolved phase in solution due to the more reducing environment inside... 

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. 

Mobile, on-line XRF methods have been tested in the Au exploration targets. Analysis of continuous till and weathered bedrock samples shows clear variation of the contents of pathfinder elements of hydrothermal alteration. Particularly, in the weathered bedrock, the presence of narrow mineralized veins is seen (Fig. 5). One interesting feature is that the indication of the weathered bedrock sources can be traced 2 to 5 m down-ice in the till. These results suggest very short glacial transport of mineralized debris from the bedrock sources. Information on...

Follow-up ground studies involved the analysis of outer bark from western hemlock collected at 100 m sample spacing over the Tl anomaly south of Tsuius Creek. This permitted more clearly defining the extent of the Tl anomaly (600 m X 600 m) and its relationship to other trace elements. Figure 1 shows the Tl anomaly and the spatial relationship of Hg which appears to define a conjugate set of lineaments interpreted as leakage from structural weakness. The multi-element association at this locality suggests that Tl and Hg may be pathfinder elements to concealed base-metal mineralization.
