Alexander Klimchouk
The Leading Scientist at the Institute of Geological Sciences of the National Academy of Sciences of Ukraine, Corresponding Member of the National Academy of Sciences of Ukraine, member of the National Council of Ukraine for Science and Technology. Born in Odessa, Ukraine, in 1956. Earned MSc degree in geomorphology from the Kiev State University (1983) and PhD in hydrogeology from the National Academy of Science of Ukraine (1998). Primary research interests lay in karst hydrogeology and geomorphology, with a particular focus on speleogenesis and hypogene karst. Authored and co-authored more than 300 scientific papers and books on various aspects of karst and cave science, edited several major international books. Began caving since 1968, when I was eleven. Published my first scientific paper in a recognized peer-review journal in 1972, when I was sixteen. Most of my caving, exploration and research was in various regions of the former Soviet Union (Western Ukraine, Crimea, Central Asia, Caucasus and the Russian North), but also in Brazil, Britain, Canada, China, Ethiopia, Germany, Italy, Slovenia, Spain, Turkey, USA and many other countries. Led numerous exploration and research expeditions. In the past, I served as a President of Kiev Speleological Club, Vice-President of the Natl. Association of Soviet Speleologists, Bureau Member and Vice-President of the International Union of Speleology (UIS). A founder and ex-President (1992-1998, 2004-2006) of the Ukrainian Speleological Association.

This study in the Antamina area in the east side of the Cordillera Occidental, home to the world largest known skarn copper-zinc deposit, demonstrates that the current karst system has formed as the result of polygenetic and multi-phase development. Structure-controlled hypogene cave systems are well-preserved and widespread in the area and present a foremost example of endogenous hypogene speleogenesis related to magmatic intrusions. Hypogene karst structures have strongly influenced subsequent epigene karstification, which commenced at the Pliocene-Pleistocene boundary. Changes in the base-level position due to the landscape evolution and Pleistocene glaciations were major additional factors that influenced epigene karst development. The findings of this study are potentially relevant to assessing karst origin and hydrogeology in many carbonate-hosted ore deposits in the Peruvian Andes and other regions. This study shows that the speleogenetic and evolutionary approach is indispensable in the development of sound conceptual models of groundwater flow in karst terrains and the assessment of karst-related hazards and risks.

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.
