ABSTRACT The results of a soil geochemical survey of the Canadian Maritime provinces and the northeast states of the United States are described. The data presented are for the <2-mm fraction of the surface layer (0-5 cm depth) and C horizons of the soil. Elemental determinations were made by ICP-MS following two digestions, aqua regia (partial dissolution) and a strong 4-acid mixture (near-total dissolution). The preliminary results show that Hg and Pb exhibit elevated abundances in the surface layer, while As and Ni exhibit abundances that can be attributed to the geological provenance of the soil parent materials.

A series of three workshops held in 2002 - 2004 included stakeholders representing about 50 North American governmental agencies, academia, environmental consultancies, and the medical community. The workshops resulted in a set of recommended sampling and analytical protocols for a soil geochemical survey that would meet the needs of this diverse set of customers. The Project is... [Pg.189]

We thank the many stakeholders who participated in the various workshops and provided valuable guidance in the design of the continental-scale soil geochemical survey. We also thank all the people who have, to date, participated in sampling in all three countries. [Pg.191]

Geochemical surveys at the GSC are generally conceived and executed as individual entities, optimised for the local geography and for the scientific objectives of the funding project. The only major exception to this approach is the National Geochemical Reconnaissance (NGR) program, which has been collecting and... [Pg.389]

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. [Pg.391]

The National Geochemical Survey of Australia 2009 update on progress... [Pg.393]

The nation-wide geochemical survey was initiated because there is no complete geochemical coverage available for Australia. Experience elsewhere shows that such a data layer is an important complement to other national-scale geological and geophysical datasets. [Pg.393]

Some regional geochemical surveys have been carried out in parts of Australia, but no national coverage exists. Since the inception of the concept of regional geochemical surveys in the 1960s, they have proven to be a reliable tool for mineral exploration. [Pg.394]

Fig. 3. Distribution of catchments sampled for the National Geochemical Survey of Australia, as at 31 December 2008 (1078 catchments, or 78%, completed).

A national-scale geochemical survey of Australia is under way. It applies ultra low sampling density to transported and well-mixed outlet sediments, which are expected to represent the average composition of large catchments. The NGSA will provide the first complete, internally consistent geochemical data layer for Australia and is expected to find applications in energy and mineral resources exploration. [Pg.396]
