Lithological and structural controls of cave development
Abstract:
This Chapter summarizes the important general controls that lithology and geologic structure impose on most cave genesis: rock purity, the presence of interbedded clastic rocks and adjacent or interbedded sequences of sulfates and carbonates, and various kinds of initial porosity, fissures in particular. Lithological and structural conditions for speleogenesis evolve throughout sedimentation, eogenesis, mesogenesis and telogenesis and change drastically between these stages. Inheritance in the evolution of different kinds of pre-speleogenetic porosity causes increasing heterogeneity in their distribution and parameters, which reaches the highest degree at the stage of rock emergence to the shallow subsurface and the surface after burial. The importance of fabric-selective porosity and stratigraphical elements diminishes with time in favor of fissure network porosity. Fissures evolve at different stages of the rock evolution. Networks are composed of complex planar and curvilinear surfaces interconnecting in three dimensions, constructed from fissures of various origins, generations and ages. The initial structural conditions for speleogenesis thus can be very varied depending on which particular stage speleogenesis commences. Conditions in deep-seated settings favor uniform speleogenetic development, while in shallow settings increased heterogeneity in fissure parameters can favor selective development. Modeling of conduit initiation and early development needs to take into account a great variability of initial permeability structures between common geological environments and evolutionary stages, especially rather dynamic non-dissolutional changes of these structures in shallow settings.
