My question is general. What do you conclude if your variogram is wavy? Cyclic patterns? I have what appears to be high nugget, followed by a wavy pattern.
If you wish, here is more info: an offshore placer platinum deposit, not too many boreholes - just 29 from decades ago spanning several square kilometers. The variogram (from GEOEAS) of the grade (ln) is given in: http://www.faculty.uaf.edu/ffrg/Variogram.zip The variogram is cyclic. Goes up and down. I tried various lags/directions. I will try to dig up the geological information and see what it says. -- Rajive
