In diamond alluvial deposits, the information about the spatial
distribution of stone size is of crucial importance for the
quantitative characterisation of the different areas of the
deposit. In fact, the value of the diamond reserves depends
strongly on the distribution of stone sizes: between two areas with
the same grade, the most valuable is the one with larger stones.
The geological genesis of the mineralization, related with the
transport and deposition of stones in trapsites, can create
separated spatial areas, corresponding to different stone size. To
characterise these distinct areas, the non smooth transitions
between them should be accounted for, in the estimation of internal
properties. An extended version of zonal control of geostatistical
estimation (Soares et ai, 1995) proposed in this paper, aims to
characterising the classes of size histogram for each geological
unit, avoiding the smooth effect. For this purpose the morphology
of each geological unit is obtained by using two distinct criteria:
i) first, the points of each unit are classified according to the
local and global probabilities of belonging to each unit (Soares,
1992); ii) in a second classification, the optimization technique
of Simulated Annealing is used to rearrange the pre-classified
points in order to impose, in the final morphological maps, the
spatial variability of experimental samples (Goovaerts, 1994). A
case study of a diamond alluvial deposit with two geological units
with distinct stone size histograms is presented.
