This book illustrates the diversity of hypogene speleogenetic processes and void-conduit patterns depending on variations of the geological environments by presenting regional and cave-specific case studies. The cases include both well-known and newly recognized hypogene karst regions and caves of the world. They all focus on geological, hydrogeological, geodynamical and evolutionary contexts of hypogene speleogenesis. The last decade has witnessed the boost in recognition of the possibility, global occurrence, and practical importance of hypogene karstification (speleogenesis), i.e. the development of solutional porosity and permeability by upwelling flow, independent of recharge from the overlying or immediately adjacent surface. Hypogene karst has been identified and documented in many regions where it was previously overlooked or misinterpreted. The book enriches the basis for generalization and categorization of hypogene karst and thus improves our ability to adequately model hypogene karstification and predict related porosity and permeability. It is a book which benefits every researcher, student, and practitioner dealing with karst.

This book focuses on the opening and exploration of more than 350 previously undiscovered caves of the Slovenian Karst, discovered during motorway construction work. The summarizes the planning of traffic roads and presents the new findings obtained during construction, as well as studies on newly-discovered karst phenomena and karst waters and their protection. Earthmoving work during construction has revealed a cross-section of the surface of the Classical Karst, covered karst with famous underground stone forests and unique karst in breccia. Research conducted in these caves has yielded a number of new findings on how the karst surface and underground were formed, on the flow of water through karst aquifers, and on the evolution of karst on various types of rock and under various conditions. The work was written by researchers from the ZRC SAZU Karst Research Institute and the Institute of Geology AS CR. The reader will benefit from the authors’ collaboration with planners and builders, which offers valuable insights for the planning and execution of their own activities in karst regions.
