The spatial distributions of mineralisation

The concept of fractal spatial distributions mineralisation has been widely proposed since Mandelbrot (1965) who emphasised the stable Pareto-Lévy distribution as relevant distribution. a is used basis for estimating endowment and erecting exploration models based on self-organised criticality. This paper explores proposition that growth kinetics mineralising system are reflected in probability describe patterns mineralisation. We revisit data sets ask question: What best fit mineralisation? answer is: members Extreme Value Distribution family (Gumbel-, Fréchet- Weibull-distributions) not Pareto Thus, although tails can be or resemble power-laws. standard box counting procedure point establishes nearest neighbour hence, by definition, resulting Weibull Pareto. mass Fréchet extreme end Gumbel. discuss implications these generate sites within underlying thermodynamics.
