Beschreibung / Inhaltsverzeichnis: In this book geological the conditions of speleogenesis in the Miocene gypsum in the Western Ukraine are characterized, particularly the role of lithological and structural prerequisites in speleogenesis. The special attention is given to structural and textural unhomogeneities in the gypsum stratum and to their role in the formation of fractures. Fracture systems in the gypsum and the structure of the unique maze cave systems are examined in details. It is shown that speleo-initiating fractures in the gypsum strata belong to the lithogenetic type and form largely independent multi-storey networks, with each storey being confined within a certain vertical structural/textural zone (unit) of the stratum. This determines the multi-storey structure of the caves in the region. Two problems related to structural and textural characteristics of the gypsum stratum are discussed in details: the formation of giant dome structures by way of gypsum recrystallization during the synsedimentary and early diagenesis stages, and the genesis of fractures. Speleogenetic realization of the existing structural prerequisites occurred under conditions of a confined multi-storey artesian aquifer system due to an upward flow across the gypsum from the under-gypsum aquifer.

Beschreibung / Inhaltsverzeichnis: The Encyclopedia of GIS features an alphabetically arranged comprehensive and authoritative treatment of this subject matter. Authored by world experts and peer-reviewed for accuracy and currency, the entries explain the key software, data sets, and processes used by geographers and computational scientists. Nearly 200 topics include major overviews, such as Geoinformatics, Spatial Cognition, and Location-Based Services. Short entries define specific terms and concepts, such as the Global Positioning System, Digital Elevation/Terrain Model, and Remote Sensing. Larger entries include key citations to the literature, and (online) internal hyperlinks to definitional entries and current standards.The reference will be published as a print volume with abundant black and white art, and simultaneously as an XML online reference with hyperlinked citations, cross-references, four-color art, links to web-based maps, and other interactive features.
