TOS vs geostatistics—again?

  • Dominique Francois-Bongarcon

In a paper presented by the first author at the WCSB1, the intimate relationships that exist between the theory of sampling of broken material (TOS) and the discipline of geostatistics were examined for the first time. In a nutshell, if TOS cannot be mentioned without reference to Pierre Gy’s lifetime fundamental contributions, it can neither be fully understood if outside the geostatistical reference frame. TOS calls for geostatistical concepts at the small scale (through Gy’s formula and the liberation factor), mixes with it at medium scale (sampling regime of one-dimensional flows) and is also very much needed by larger scale geostatistics (data quality in view of estimation, conditional simulations).
