Isofactorial models for granulodensimetric data

  • M. Armstrong
  • G. Matheron


Existing isofactorial models developed for disjunctive kriging using a cutoff grade on one variable are extended to the bivariate case which arises when dealing with granulo-densimetric data, such as are obtained from coal washing or mineral processing.

Key words

bivariate isofactorial models disjunctive kriging granulodensimetric data coal washing mineral processing
