Book Description
This book is mainly concerned with the geomorphological aspects of caves - karst hydrology, speleogenesis and the origin of speleothems. Cave exploration was a necessary prerequisite for such studies and its progress is traced from prehistoric times to the systematic regional investigations of the 1 7th century and later. The first extensive work was in Slovenia, stimulated by the practical importance there of karst hydrology for water supply and flood control. Large karst springs had long attracted attention and several hypotheses had already been advanced; according to some they were supplied by water raised from the sea, others explained them by condensation and finally their source as rainfall was accepted. The study of intermittent karst lakes led eventually to the postulation of what amounted to a water table.A true understanding of speleogenesis and the origin of speleothems depended on a knowledge of the chemistry of limestone solution, which in its tum depended on the rejection of phlogiston at the end of the 18th century. Before that time only mechanical erosion was normally conceived as a means of removing particles of solid rock and subsequently redepositing them to form speleothems, although a few people earlier in the century had involved an unspecified "aerial acid". There were also several more primitive theories including the formation of caves by tectonic "catastrophes", by erosion as the water of Noah's Flood drained back underground, and the inflation of cavities in still soft limestone by decomposition gases. For many years speleothems were thought to possess a low form of life, growinglike plants rather than by accretion.After the action of carbon dioxide in speleogenesis was appreciated a new question arose - whether caves could be formed in the saturated zone or whether they were due solely to vadose water. For many years the problem was not recognised but violent controversy was taking place over it by the end of the 19th century.

Book Description
Caves are some of the creepiest and coolest places on Earth. Brave scientists known as cave geologists venture into their dark depths in order to learn more about these extreme places. Thanks to detailed text and photographs of cave geologists at work, readers can feel like they’re in mysterious caves alongside these scientists. Cave geologists use science, technology, engineering, and math to do their research and to stay safe in this dangerous environment. In learning about this career, readers also learn about important topics in STEM-focused science curricula. Fun fact boxes and a graphic organizer enhance this exciting reading experience.

Book Description
The present publication on karst hydrology and physical speleology combines two subjects which have up to now been treated separately. The two fields of knowledge have gone their separate ways, less as a result of differences in subject matter than of varying approaches. The focal point in karst hydrology lies in the description of subter ranean water with its physical and chemical properties, whereas physical speleology de scribes subterranean cavities with their contents (air, water, and sediments), which gen erally have been created by water. Such cavities can be correctly interpreted only by means of a knowledge of karst hydrology, yet they in turn yield indications of the pro perties of karst water. Karst hydrology and physical speleology are thus two aspects of the subterranean karst phenomenon and should be viewed congruently. This book addresses geologists, hydrologists, geomorphologists, geographers, and karstologists, above all speleologists, as well as all friends of caves, especially the cavers among them. Its contents must therefore appeal to two groups: on one hand to the academically trained, whether university faculty, graduates, or students, who as a rule have the necessary basic knowledge to be able to understand the theoretical com ments; on the other hand to the laymen, who have fust-hand experience from their own observations in caves, but who often do not dispose over the scientific foundation necessary for an understanding of the phenomena. Therefore occasionally more attention will be given to problems of a simpler nature and to questions of technical terminology.
