An evolution of the Slovak part of the Danube Basin has started with transtension-extension spreading of the crust [Paleogene(?) to Ottnangian(?), Karpatian, and lower Badenian]. This pro-tostage of the evolution has been an important factor in the further evolution of the basin, but the dominant element, from the viewpoint of the evolution of the Slovak part of the Danube Basin and also its broader surroundings, appears to be the Ulany ridge. This ridge connected (as an interbasinal ridge) the evolution of the Slovak part of the Danube Basin and of the Vienna basin into one dynamic context until the end of the crustal extension phase (lowest Panno-nian). In that way, the Ulany ridge controlled the bivergent extension (toward northwest-west and southeast–east) from the north–northeast–south–southwest axis of the ridge uplift. The recent structural inexpressiveness of this ridge is caused by its tectonic unroofing in the crustal extension phase, erosion, and later (upper lower Pannonian to Holocene) thermal collapse in the basin.

This volume of 30 chapters authored by 107 geologists and geophysicists from Austria, Czech Republic, Hungary, Poland, Romania, Slovakia, Ukraine, United Kingdom, and the USA provides a comprehensive and understandable account of geology and hydrocarbon resources of the entire Carpathian system from northeastern Austria to southern Romania, including the Neogene foredeep, the foreland platform both in front and beneath the thrust belt, the Carpathian thrust belt, and the late and post orogenic intermontane basins. Principal chapters on regional geology are supplemented by thematic contributions on geodynamic reconstructions, regional geophysical investigations, hydrocarbon systems, and case studies of major oil and gas fields. To date, close to 7 billion barrels of oil and more than 53 trillion cubic feet of natural gas have been produced from the entire Carpathian system. Additional new reserves may be found, especially at deeper structural levels below the Neogene foredeep and the thin-skinned Carpathian thrust belt. Seventeen chapters of Memoir 84 have been printed in full. The remaining chapters have been printed as abstracts only, with the full paper for all 30 chapters as .pdf files on the CD-ROM in the back of this publication. The publication is intended as a source of information to schools, governmental and private institutions, oil companies, and potential investors.
