This book describes Sicily’s unique and varied karst features, discussing the notable geographical areas, their lithology and genesis and, in a number of cases, their value as geosites to be preserved for scientific or tourism purposes. The rich variety of Meso-Cenozoic outcropping rocks in Sicily make the island highly significant in terms of the geological history of the Mediterranean area. The soluble rocks (limestones and gypsum), widely present on the island, play an important role in shaping and continuously altering the landscape, both in the reliefs with spectacular fluviokarst cayons and suggestive gorges, and below ground where there is a wide range of speleogenically and speleologically important caves.
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.
The book presents an overview of the main hazards affecting karst, including collapse and subsidence phenomena, hydrological hazards and human-induced geohazards. Consideration is also given to the problems of geohazard management in karst. The geological and hydrological properties of karst terrains make them among the most fragile in the world and pose serious problems for land managers. Sustainable development in these terrains requires efforts to limit geohazards of anthropogenic origin and to recognize and mitigate against those of natural origin. Aimed at providing the reader with worldwide case studies, the contributions cover a range of geological and morphological settings. Geographically, the fourteen papers discuss very different karst areas, from North America, the Caribbean and Asia to several karst areas in Europe, including the British Isles, Spain, France and Italy.
Knjiga Evolution of karst: from prekarst to cessation (Razvoj krasa: od predkrasa do izginotja) je zbornik istoimenskega simpozija, ki je v septembru 2002 potekal na Inštitutu za raziskovanje krasa ZRC SAZU. Namen knjige je odgovoriti na vprašanja, kot so: Kdaj se začne kras in kdaj končač Kateri procesi in dogodki določajo razvoj kraškega podzemlja in površjač Kako je razvoj krasa povezan s pretakanjem voda v kraškem vodonosniku in kako z razvojem in razširjenostjo bioloških vrstč Kako merimo čas, ki je minil od določenih dogodkov v krasuč
Karst Hydrogeology, Geomorphology and Caves A Comprehensive Resource Covering All Aspects of Karst Hydrogeology, Geomorphology, and Caves This essential book covers all physical, chemical, and geological aspects of karst science. It reviews current knowledge on hydrogeology, geomorphology and caves in karst, based on the vast existing literature and investigations carried out by the authors worldwide. The different topics are profusely illustrated with color figures and images from all continents and climates, showing the scientific and aesthetic appeal of karst environments. The book covers in a systematic way the significant features of karst rocks, the chemistry and kinetics of their dissolution, the rate and distribution of karst denudation, the unique hydrogeology of karst terrains, the landforms endemic to karst, the morphology of caves and their diverse sedimentary records, and the multiple processes that lead to the formation of underground voids. Overall, the work reflects the increasing recognition of karst as a fundamental part of the Earth’s dynamic systems, and helps readers understand this multidisciplinary field from a holistic and nuts-and-bolts perspective. Some of the ideas discussed within the book include: How karst is gaining importance for human development, because of its valuable resources (groundwater) and associated environmental problems (impacts and hazards) The enormous technological developments achieved in recent years Recent major breakthroughs in the field and their influence on other scientific disciplines The central role played by karst science for understanding and mitigating global environmental issues (global warming, depletion of resources, human-induced hazards) For all scientists working in karst, and for students and lecturers of karst-related programs, this book serves as a valuable all-in-one source. It is also a valuable resource for professional hydrogeologists, the petroleum industry, environmental geologists, and of course speleologists, the last true geographic explorers in the world.
This book offers as comprehensive an overview as possible of the lithostratigraphy of the Italian region of Sicily, taking into account the multiplicity of formational and terminological variability developed over more than a century of studies and publications. It presents stratigraphic terminology, the geological lexicon and the main stratigraphic subdivisions that are not familiar to Sicilian geologists. The new stratigraphic methods and the use of formations as mapping units have prompted the acquisition of new lithostratigraphic data, and a review of the previous units and their comparison with the new collected data, enabling the definition of a number of new lithostratigraphic units. The book summarizes the results in 77 worksheets containing the most important information regarding the lithological, sedimentological and microfacies characteristics, the measured thicknesses, areal extent and the regional aspects, the paleoenvironmental, paleogeographic and paleo-tectonics setting, compiled according to standard procedures and nomenclature rules provided by the International Commission on Stratigraphy (ICS).
Rock features are important traces of the formation and development of karst surface. On various karren their record is especially rich, revealing to us the many factors that in diverse conditions formed the karst surface on various carbonate and other rock.We have tried to present the most characteristic rock features and through them the most important factors and processes in the formation of the karst surface, the methods of studying them, and the most outstanding examples.Forty-nine contributing authors offer a wide spectrum of content and examples of rock forms from many karst regions around the world.The first part of the book offers an orderly-organized survey and description of the most characteristic rock forms and presents the physical and chemical corrosion of rock, biocorrosion, the modeling of rock forms, their detailed morphometrics, and numerous descriptions of individual rock forms. The second part is devoted to various examples of rock forms found around the world from Slovenia through North and South America to Australia and Asia.
Prepared by some of the world's leading experts in the field, this book is the first summarizing work on the origin, importance and exploitation of paleokarst. It offers an extensive regional survey, mainly concerning the Northern Hemisphere, as well as a thorough analysis of the problems of research into paleokarst phenomena, with particular emphasis on theoretical contributions and practical exploitation. By concentrating on phenomena which have appeared in the course of geological history, the book represents a substantial development in the general theory of paleokarst and demonstrates the advantages of a comprehensive approach to the problem. Considerable emphasis is put on the economic importance of paleokarst phenomena, from the point of view of exploiting significant deposits of mineral raw materials, as well as from a civil engineering and hydrological point of view.Since the publication deals with a boundary scientific discipline, it is intended for specialists from various branches of science: geologists, paleontologists, economic geologists, geographers, mining engineers and hydrogeologists.
Ancient Greek migrants in Sicily produced societies and economies that both paralleled and differed from their homeland. Explanations for these similarities and differences have been hotly debated. On the one hand, some scholars have viewed the ancient Greeks as one in a long line of migrants who were shaped by Sicily and its inhabitants. On the other hand, other scholars have argued that the Greeks acted as the main source of innovation and achievement in the culture of ancient Sicily, a culture that was still removed from that of mainland Greece. Neither of these positions is completely satisfactory. What is lacking in this debate is a basic framework for understanding ancient Sicily's social and economic history. Archaic and Classical Greek Sicily represents the first ever systematic and comprehensive attempt to synthesize the historical and archaeological evidence, and to deploy it to test the various historical models proposed over the past two centuries. It adopts an interdisciplinary approach that combines classical and prehistoric studies, texts and material culture, and a variety of methods and theories to put the history of Greek Sicily on a completely new footing. While Sicily and Greece had conjoined histories from the start, their relationship was not one of periphery and center or of colony and state in any sense, but of an interdependent and mutually enriching diaspora. At the same time, local conditions and peoples, including Phoenician migrants, also shaped the evolution of Sicilian Greek societies and economies. This book reveals and explains the similarities and differences between developments in Greek Sicily and the mainland, and brings greater clarity to the parts played by locals and immigrants in ancient Sicily's impressive achievements.
