Large Deposits of Pellet Phosphorites

It is proposed a bidimensional mathematical non-deterministic modell applied to study solid objects in sedimentary floors. It has been used to the aleatory nodular variables (radius and spacing). The required parameters have been determined from the dimensions of the average phosphorite nodules within the California borderland area. It has been used random distributions of representative cross section in very thin layers. It has been calculated 1) the average surface concentration of large deposits of pellet phosphorites 2) the reserves of sea-floor phosphorite of the world. These analytical results are in agreement with the ones obtained in earlier discovered oreshoot.
