THROUGHOING FLUID-CONDUCTING STRUCTURES: MORPHOGENETIC CLASSIFICATION AND CHARACTERIZATION OF TYPES

Throughgoing fluid-conducting structures are the main elements of plumbing system sedimentary cover and play an important role in fluid migration, evolution basins lithogenesis, formation fluidogenic deposits (including hydrocarbons metals), use geothermal energy sources, risk assessment for geological depositories radioactive wastes, CO2 other materials. They widespread characterized by a variety morphology origins, but poorly systematized these attributes, which complicates identification interpretation structures. In this article, based on analysis generalization literature sources data from own field studies, morphogenetic classification throughgoing is developed characteristics defined types given. At first level, such divided into four groups according to nature dominant processes: tectonic, fluidodynamic, karstic (dissolution) karstic-gravitational. second third levels, distinguished structural-morphological material features, taking account peculiarities mechanisms conditions formation. The some clarified. It shown that karstification, particularly hypogenic, leading process most permeable and, accordingly, contrasting hydrogeological anomalies their consequences. Structures relatively small vertical dimensions stratigraphic coverage (bed-crossing, suite-crossing) can be elementary unambiguous although they frequently show signs superimposed changes significantly affect fluid-exchange function. proposed applicable mainly structures, while large (cross-formational, cross-sedimentary cover) usually complex origin, potentially involving combined or sequential action tectonic hydraulic rupture, fluidization, metasomatism, dissolution / karstification collapsing. This polygenetic due mechanical heterogeneity sections host strata properties fluids during upward as well over time. However, assignment certain genetic categories carried out processes.
