This thesis addresses karst development in a terrain characterized by a highly complex geological and geomorphological evolution. It tackles the extent and complexity of both epigenic and hypogenic karst development, based on morphological analyses of caves, combined with analyses and datations of cave sediments and their correlation to regional geological and geomorphological evolution. Hypogenic karst registered is mainly the result of hydrothermal speleogenesis due to increased geothermal gradient in connection with nearby Pliocene-Pleistocene volcanic centers, with occurrence of sulfuric acid speleogenesis and ghost-rock weathering due to local geological or lithological control. Epigenic speleogenesis is strongly controlled by base level oscillations, with also examples of deep phreatic (now fossil) caves connected to regional base level rise, and per-ascensum speleogenesis. Another important finding is the constraining of the timing of Mariovo Lake draining in the Pleistocene, an important event in order to understand the geomorphological evolution in Macedonia, as it led to the onset of fluvial development and incision of valleys, shaping most of the present morphology.

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

Originally published in 1989, Karst Geomorphology and Hydrology became the leading textbook on karst studies. This new textbook has been substantially revised and updated. The first half of the book is a systematic presentation of the dissolution kinetics, chemical equilibria and physical flow laws relating to karst environments. It includes details of the many environmental factors that complicate their chemical evolution, with a critique of measurement of karst erosion rates. The second half of the book looks at the classification system for cave systems and the influence of climate and climatic change on karst development. The book ends with chapters on karst water resource management and a look at the important issues of environmental management, including environmental impact assessment, environmental rehabilitation, tourism impacts and conservation values. Practical application of karst studies are explained throughout the text. "This new edition strengthens the book's position as the essential reference in the field. Karst geoscientists will not dare to stray beyond arm's reach of this volume. It is certain to remain the professional standard for many decades." Journal of Cave and Karst Studies, August 2007

This is the first study of the karst areas of China to be carried out by a Western geomorphologist, and almost all the sources are from Chinese works, as yet unpublished in the West. Karst areas are sensitive to environmental influences and Chinese attempts to deal with these are discussed here, as are Chinese methods of studying karst since they differ somewhat from those in the West. Finally, the author compares karst areas in Europe and elsewhere with those in China. The book is illustrated by numerous diagrams from Chinese sources as well as the author's own photographs.

This book presents (i) a comprehensive methodological approach in analyzing karst surface features using contemporary GIS tools of high resolution applied on a large study area and extensive dataset, (ii) a revision and evaluation of the existing concepts valid in the modern karst geomorphology, (iii) a detailed elaboration of overlooked and yet undefined karst surface features, and (iv) an innovation in the discussion on origin and evolution of karst surface features. The book contains the first example of such comprehensive application of the modern technologies in spatial analysis in the field of karst geomorphology, and it offers several new methodological and theoretical perspectives and presents numerous starting points for further research. It contributes both to the understanding of the local karst evolution and to the knowledge of karst surface features globally.
