On the material of the thoroughly studied Deputatskoye tin ore deposit (Yakutia) the research aimed at revealing the possibility of describing the structure of the deposit by a deterministic fractal model has been carried out. The essence of the study is the search for a function mapping a large structure to its part. The properties of such a mapping were checked by dividing the investigated area into M x N equal-sized elements (cells), and M and N were taken equal to 8,16,32,64,128. In each cell, the average tin reserves in metric percent were calculated and the similarity between the reference (8 x 8 cell) and the object as a whole was assessed, taking into account the possible rotation of small-sized structures relative to large ones. It was found that the maximum number of cells similar to the etalon is revealed when using the 64 x 64 network, and the 64 x 128 network identifies as "etalon-like" the most morphologically complex nodes that are most enriched in tin.
The definition of compression and injection zones (disjunctives) and methods of their field diagnostics are given. The internal structure of such disjunctives in the form of similar elements - cells - is established. Typical structure of cells, dependence of structure on viscosity of medium, orientation of permeability areas in cells are considered. Examples of deposits with such structures are given.
Deterministic, random and random-deterministic fractal mathematical models are described. Examples of geological objects and processes that can be described by such models are given. Methods of measuring fractal parameters are given.
Рассматривается вопрос об исследовании параметров дизъюнктива с использованием опрежаюших дизъюнктив трещин по неориентированному керну разведочных скважин. Автор добивался максимальной сходимости расчетной и фактической картин и таким образом определял параметры дизъюнктива. В результате выяснено, что по данным трещиноватости керна можно определить только либо положение, либо геологический тип, дибо форму разрывного нарушения, вызвавшего трешиноватость.
