Cenozoic lithogenesis in the Baikal rift zone
Lithology and Mineral Resources, 2016New data on the geological history and Cenozoic lithogenesis in depressions of the Baikal rift zone are considered with areas adjacent to Lake Baikal as example. In this region, rifting developed during the plain (Late Oligocene‒Early Pliocene) and orogenic (Late Pliocene‒Holocene) stages and was accompanied by the accumulation of plain coaliferous fan

Petroleum Geoscience, 2018
Transform zones present fascinating geometry and tectonic deformation, some of which can be confusing, especially, when rift and transform zones interact, and rift structures are displaced by transform fractures. A case study from north Iceland includes the transform zone of Tjörnes (the Tjörnes Fracture Zone) and the Theistareykir Fissure Swarm of the

Classification of the rift zones of venus: Rift valleys and graben belts
Solar System Research, 2016The spatial distribution of rift zones of Venus, their topographic configuration, morphometric parameters, and the type of volcanism associating with rifts were analyzed. This allowed the main characteristic features of rifts to be revealed and two different types of rift-forming structures, serving for classification of rift zones as rift valleys and ...

Control on off-rift magmatism: A case study of the Baikal Rift Zone
Earth and Planetary Science Letters, 2018Abstract The Baikal Rift Zone (BRZ) is an active intracontinental rift zone with almost no rift-related magmatism along the rift axis. Most magmatism is observed outside the rift center, and e.g. the major Vitim volcanic field is displaced more than 200 km from the rift center. The reasons for this regional distribution of the magmatism are enigmatic,

Molten core model for Hawaiian rift zones
Journal of Volcanology and Geothermal Research, 1995Abstract Kilauea volcano's East Rift Zone (ERZ) is extraordinary in that abundant lateral dike intrusions and rift zone widening associated with seaward slip of the south flank over a basal fault may have allowed an extensive molten core to develop. The rift zones of Mauna Loa and the Southwest Rift Zone (SWRZ) of Kilauea do not appear to have such ...

Volcanic rift zones and their intrusion swarms
Journal of Volcanology and Geothermal Research, 1999Abstract Most volcanoes have rift zones, underlain by swarms of dykes or other minor intrusions. This paper reviews the subject and presents some new data and ideas. It plots rift zone width against length for different volcano types, and finds that the zones on strato- and central volcanoes are on the whole narrower and shorter than on other types ...

Erta Ale and the Danakil Rift Zone
2014Ethiopia may not be the first country to come to mind when considering where to find active volcanoes to visit. Located on the horn of Africa, at the southeastern margin of the Sahara Desert, Ethiopia is better known for its archeological and historical tourism, as well as its struggles with famine and concerns with neighbors South Sudan, Somalia and ...

Geochemistry of effusive rocks of Rift zones
Physics and Chemistry of the Earth, 1979Abstract The following effusive rock series within the rift zones are distinguished: tholeiitic basalts-andesites-rhyolites; basalts-trachytes and phonolites; Na-alkaline series; olivine melanonephelinites-nephelinites and phonolites and K-alkaline one: katungites-ugandites-leucitites-leucitic basanites.
