Rifts and passive margins are extremely important for the petroleum industry, as they are areas of high sedimentation and can contain significant oil and gas resources. Rifts and Passive Margins provides a comprehensive understanding of rifts and passive margins as a whole. It synthesises in one volume the existing information devoted to specific aspects of these vitally important hydrocarbon habitats. This collecting together of state-of-the-art information on the topic facilitates the better use of this knowledge to assess the risks of exploring and operating in these settings and the development of systematic and predictive hydrocarbon screening tools. Rifts and Passive Margins will be invaluable for a broad range of readers, from advanced geology students and researchers to exploration geoscientists to exploration managers exploring for and developing hydrocarbon resources in analogous settings.

Michal Nemčok is a research professor at the Energy and Geoscience Institute at the University of Utah and a visiting professor at the Energy and Geoscience Institute Laboratory at the Geological Institute SAV, Bratislava, Slovak Republic. He has performed structural and hydrocarbon evaluations in numerous rift settings, such as the Pannonian Basin system of the Czech Republic and Slovakia; the Basin and Range of the western United States; the Bristol Channel Basin; the Central Basin, Democratic Republic of Congo; and the Salton Sea region in California. He has also worked in many passive margin settings, such as West India, East India, the eastern United States and Canada, the African margins of the Central Atlantic, the equatorial Atlantic, the Gulf of Mexico, the Guyana-Suriname Basin, Gabon and Cameroon, the Black Sea region and southeastern Brazil. The results of most of these studies have been presented in 32 articles published in refereed scientific journals and in two edited books. He is the co-author of Thrustbelts: Structural Architecture, Thermal Regimes and Petroleum Systems (Cambridge, 2005).
