AbstractThe locations and information about the sizes of 61 mud volcanoes on the Italian mainland and Sicily, plus an area of mud diapirism in the Italian Adriatic Sea, are presented. Data about the emission products are also provided. The majority of these mud volcanoes are found where thick sedimentary sequences occur within a zone of tectonic ...

Mud volcanoes in deepwater Nigeria
Marine and Petroleum Geology, 2000Abstract Detailed study of 3D seismic data from deepwater Nigeria has revealed the presence of features interpreted to be mud volcanoes. They occur in an upper slope environment seen as 1–2 km circular features at the seabed. Seabed cores from the mud volcanoes contain oil, gas and sand/shale–clast content richer than the seabed background.

Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]
Marine Geology, 2003 It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...

Marine and Petroleum Geology, 2009 The assessment of gas origin in mud volcanoes and related petroleum systems must consider postgenetic processes which may alter the original molecular and isotopic composition of reservoir gas. Beyond eventual molecular and isotopic fractionation due to

In this chapter, the origin of mud volcanoes in the Black Sea region is considered. This question has been debated for more than two centuries. Voskoboynikov and Gur’iev ( 1832 ) were the first researchers to study the Taman mud volcanoes; they proposed that the existence of mud volcanoes could be explained by the increasing pressure of gases due to ...

Mud volcanoes are frequently encountered geo-structures at active and passive continental margins. In contrast to magmatic volcanoes, mud volcanoes are marine or terrestrial, topographic elevation built from vertically rising fluidized mud or mud breccia. Commonly, these structures have a crater, hummocky rim, and caldera. Mud volcanism is triggered by

Marine-geologic investigations on the Arabian Sea by Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR) in 1995 and 1998, and land expeditions in 1998 and 1999 to the coastal regions of the Makran Desert/Pakistan have extended the knowledge of the aerial distribution of mud volcanoes.

The article discusses regularities in the distribution of mud volcanoes and characterizes most important mud volcanic provinces of the world. A new morphogenetic classification of mud volcanoes substantiated by results of their study in the Crimean–Caucasian and West Turkmenian regions is proposed.

Bubbling gases from the mud volcanoes of Trinidad and gases associated with oil in deeper reservoirs were sampled and analyzed to understand their possible relationships. Numerous geochemical analyses were performed on the gas samples. The chemical concentrations of organic compounds, CO2, and noble gases (from He to Xe) were measured, and isotopic ...

Mud Volcanoes and Seismicity in Romania
2005Due to the occurrence of mud volcanoes and active seismic areas in close proximity in Romania, good conditions can be found for studying the relationship between the two phenomena. The most important earthquakes are generated within the Vrancea zone, related to a lithospheric fragment sunken into the astenosphere.
