      This is a reminder about the deadline for the submission of abstracts of
      the 32nd International Geological Congress: 32nd IGC – Florence (Italy),
      20-28 August 2004.

      The deadline for submission of the abstract is the 28th of January.

      See http://www.32igc.org/ for more information.

      Between others, we have the following session that may match the interests of
      AI-GEOSTATS:

      Session G – 03.08 – Statistical and mathematical methods in land resource
      survey: application to environmental geochemistry (sponsored by IAMG and
      SoGeI)

      Conveners: Buccianti A. (Italy), Vetuschi Zuccolini M. (Italy), Dubois G.
      (Belgium)

      Description of the session:

      An important aim of environmental surveys is to delimit zones where there are
      potentially toxic materials (i.e. heavy metals) in water, stream sediments and
      soils. Environmental protection agencies often set thresholds for metal
      concentrations and the use of the land may be conditioned by these
      indications. In the session G – 03.08 a discussion of the most recent
      developments in the field of Geostatistics applied on thematic mapping in
      Geochemistry and Environmental Sciences is proposed. Geostatistics non only
      provide descriptive tools such as variograms to characterise the spatial
      pattern of the data but also various interpolation (i.e. kriging) techniques
      to predict values at unsampled locations using information drawn from
      different attributes. The fundamental contribution of Geostatistics related to
      the assessment of the uncertainty about unsampled data has to be implemented
      with a deep investigation about variogram interpretation and modelling. In
      this session variograms and their geochemical meaning are considered the
      critical point to be discussed.
