textbooks
Here's
the deal! I'll review your favorite geostatistics textbook,
point out where it strays from the straight and narrow
of mathematical statistics, and post on this website which
assumptions, decisions, dependencies and independencies, geostatistical
models, variances and covariances, semi-variograms and
semi-variance analysis, crumble under scientific scrutiny.
Reviewed books are non-returnable!
When
we were working on Precision Estimates for Ore Reserves
we scrutinized David's Geostatistical Ore
Reserve Estimation and Clark's Practical geostatistics
to learn how these authors calculate confidence limits
for metal contents and grades of ore reserves to quantify the
risk associated with an intrinsically imprecise measurement
chain. What we found out brought about an exhaustive
examination of a bizarre variant of mathematical statistics. When a disgruntled student of
Matheron's new science donated a copy of Journal and Huijbregts's Mining geostatistics, it became clear
why geostatistics cannot possibly give unbiased confidence
intervals and ranges for contents and grades of reserves.
What
geostatistics did most effectively is convert barren rock
and bogus grades into Bre-X's mind boggling phantom resource.
It does just as well with a few widely spaced, high
grade boreholes because most kriged estimates in
the infinite set, defined by two or more independently
measured values with different coordinates, converge on
the arithmetic mean, irrespective of the distance between
the selected coordinates of a kriged estimate and those
of the measured values. In a text titled
"Sampling and Statistics", I
shall juxtapose mathematical statistics and geostatistics
on the basis of numerical examples in these textbooks.
In 2004, I asked IAMG's President, who is also JMG's Book Reviewer, to make available the following textbooks,
Basic linear geostatistics
Armstrong, M, Springer, 1998
Geostatistics for environmental scientists
Webster, R and Oliver, M A, 1998
Applied mineral inventory estimation
Sinclair, A J, Cambridge, Apr 2002
I would like to post my reviews before the end of 2005 but have yet to receive any of these textbooks.
