Geochemical surveys procedures

All modern relational databases include the ability to export tables as XML files. It is usually possible to apply an XSLT transformation to the data as part of the export procedure. In the interest of simplicity and compatibility across different databases, no special transformation was applied to the tables extracted from the New Brunswick till database. Therefore, after exporting data out of MS Access in a generic XML format, the first XSLT transformation involves restructuring the data to conform to a Geochemical Survey XML schema, developed at the GSC (Adcock 2009b). The second transformation produces a set of files which conform to the GML schema (OGC, 2007). KML shares many features with GML, and hence the third and final GML-to-KML transformation is very simple. 

Soil samples are usually collected at the surface proper or at depths of up to several metres below the surface. As far as possible, samples are kept in their original condition until they are prepared for analysis in the laboratory. The analytical procedures are invariably partial extraction techniques. This approach has been widely used in other branches of exploration geochemistry, but assumes particular importance in gas geochemical surveys for petroleum.
