ИСТИНА

Biogeochemical processes occurring in subterranean environment (caves and mines) can be defined as "extreme", because of many environmental factors are limited, absent or have specific character. In these specific ecosystems, the process of formation soil-like objects occurs as a result of interactions between the biota and the mineral layer bordering it, but this process significantly differs from soil formation on the “normal’ sun-light surface. The method of stable isotopes allowed to characterize the features of subsurface cycles, and to study the influence of local factors on the processes of biomineral interaction.
