Sažetak
Stochastics, especially simulations, occasionally could be found in different geological calculation, mostly as the most advanced mapping methods. Their main attribute is description of uncertainties that are inherent to any geological mapping dataset, but also to any volumetric or probability calculation. Here are presented uncertainties in all of those three cases – mapping, volume calculation and probability calculation, and ways why and when to use stochastics in them. The stochastics, and consequently simulation, is recommended tool in case of low number of data (less than 15) or large dataset (more than 40 inputs), but in both cases the descriptive statistics needs to be known and reliable. Almost the same could be applied in volumetric, but stochastic in probability of success calculation could be introduced only in larger datasets, with 15 or more inputs.
