This chapter summarizes the present data on the change of the thickness of the lithosphere in the Carpathian-Pannonian region obtained by seismics and seismology, and magnetotelluric and gravity studies, emphasizing the updoming of the asthenosphere below the Pannonian Basin in accordance with its high heat flow. Important conclusions have been drawn from the stripped gravity map concerning the deep crustal structures, including the intrusion in the narrow subbasins. Special attention is paid to the narrow rift zone of the Bekes subbasin with high-density mafic intrusion in its crust and the elevation of Moho and asthenosphere during the rifting as it was stated by reflection seismics and interpretation of magnetotelluric sounding measurements and supported by stripped gravity map and gravity modeling.
Figures & Tables
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.
