Rift zone abandonment and reconfiguration in Hawaii: Mauna Loa's Ninole rift zone

Geology, 2010
A new onshore-offshore three-dimensional seismic velocity model for the Island of Hawaii reveals a massive buried rift zone within Mauna Loa9s southeast flank, introduced here as the Ninole rift zone. This feature extends more than 60 km south of Mauna Loa9s summit, spans a depth range of ∼2–14 km below sea level, and is the probable source of the 100 ...

Baikal rift zone: Structure and geodynamics

Tectonophysics, 1992
Abstract The Cenozoic Baikal rift zone is superimposed on the Caledonian Baikal fold belt, representing the suture between the Precambrian Siberian craton and several microcontinents. The Baikal rift zone consists of a system of disconnected fault-bounded basins and extensional and wrench faults that straddles a major arch, having a topographic ...

Rift interaction zones and the stages of rift linkage in active segmented continental rift systems

Basin Research, 2021
AbstractAlthough much is known about the interaction of faulting and sedimentation within the basins of active segmented continental rift systems, little is known about these processes within the interaction zones of varying geometries that separate the young interacting segments.

Aeolian deposits of rift zones

Quaternary International, 2011
The evolution of contemporary aeolian processes in continental rift zones is one of the poorly explored issues in Quaternary geology. Associated with rift zones is the formation of aeolian zircon-rutile-ilmenite sands which are rich in various mineral resources and, primarily, in titanium, zirconium, uranium, and in other rare-earth elements. Using the

Surface deformation in volcanic rift zones

Tectonophysics, 1983
Abstract The principal conduits for magma transport within rift zones of basaltic volcanoes are steeply dipping dikes, some of which feed fissure eruptions. Elastic displacements accompanying a single dike emplacement elevate the flanks of the rift relative to a central depression.

Petrologic constraints on rift-zone processes

Bulletin Of Volcanology, 1989
The Puu Oo eruption in the middle of Kilauea volcano's east rift zone provides an excellent opportunity to utilize petrologic constraints to interpret rift-zone processes. Emplacement of a dike began 24 hours before the start of the eruption on 3 January 1983.
