Abstract
This paper is concerned with the distribution of heat flow in the Baikal Rift Zone, the Shanxi-Liaohe Rift, the Jordan Rift, and in the Orly (Storoya) Trough in the northern Svalbard plate, as well as in the rift zone of Iceland. One notes an asymmetry in heat flow about the rift axial line compared with adjacent areas upon the background of its higher value. The origin of this asymmetry is due, not only to differences in the permeability of the faults in the sides of the rift structure, but also to planet-wide factors, in particular, the Coriolis force. The north–south rift structures considered here are situated in the northern hemisphere; their eastern flanksshow increased heat flow compared with the western flanks, and this is in agreement with the Coriolis force vector in the Earth’s northern hemisphere. The geothermal asymmetry in oceanic crustal divergent zones as noted previously is also seen in pull-apart structures of continental rift zones.
期刊介绍:
Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
