For a long time the features of biomineral formations in human organism exclusovely persisted in the interests of medicine with its habitual methods of researches. Main attention was given to the diagnosis and treatment of diseases that conduce to the nascency of pathological formations. At the same time it is obvious, that precise representation of the reasons of their occurence and the mechanism of the further formation has important meaning. Now these questions are widely studied with the involvement of mineralogists and used in mineralogy methods of investigations.

At the present time the crystallographic problems are defined precisely enough. The analysis of composition of individual stones during daily hospital work and statistical analysis with the view of general medical researches, studying of a texture and growth of corresponding crystals, researches in vitro which can lead to prevention of diseases or dissolution of stones are concerned in those problems.

In this relation we shall note that in the second half of 20th century the urolithiasis was everywhere characterized by the prelevance of oxalate (from 58,2 up to 87,8%) and rather low level of uric acid stones (from 1,3 up to 17,6%). The homogeneouse chemical structure of concrements was found out rarely and mainly among urates. The great bulk of the uric stones had the mixed structure, though calcium oxalate met in 63–67%. Despite of traceable mixed structure of stones, search of the law, that allows the prediction of chemical compound of concrement, levels of infringement of metabolism proceeds. It is done for definition of an opportunity off implementation of litolitical (destroying stones) therapy. But formation of organ-meniral aggregates is the multidimentional process that is appreciably caused by features of ontogenesis. Each separately considered existing theories of lithogenesis cannot describe the process of formation of stone full enough. And that dictates the necessity of attraction of the expanded methodological approach.

Thus, researches of interrelations of “crystal-organism” system to which the big attention all over the world is paid have important meaning as from the point of view of fundamental problems of mineralogy and crystal chemistry, and from the point of view of medicine with its practical problems. Joint researches of process of biogenic mineral formation by the experts in the field of medicine and mineralogy enrich and develop both directions. Specificity of local conditions (rigidity of water, a climate and so forth), occupation of the person, type of feed, at last, ecological conditions in the given region play a role here. These questions are investigated in the research on an example of features of ecology of Krasnoyarsk region.
