Accretion leading to collision and the Permian Solonker suture, Inner Mongolia, China: Termination of the central Asian orogenic belt
Tập 22 Số 6 - 2003
The Solonker suture records the termination of the central Asian Orogenic Belt
(CAOB). However, tectonic development of the Solonker suture is poorly
understood. We report new field data for the Ondor Sum melange in the Ulan
valley, and present a new evaluation of the orogenic belt extending from the
southern Mongolia cratonic boundary to the north China craton within the context
of a new geologic...
Extension in the Tyrrhenian Sea and shortening in the Apennines as result of arc migration driven by sinking of the lithosphere
Tập 5 Số 2 - Trang 227-245 - 1986
Previously proposed models for the evolution of the Tyrrhenian basin‐Apenninic
arc system do not seem to satisfactorily explain the dynamic relationship
between extension in the Tyrrhenian and compression in the Apennines. The most
important regional plate kinematic constraints that any model has to satisfy in
this case are: (1) the timing of extension in the Tyrrhenian and compression in
the Apen...
Extensional collapse of orogens
Tập 7 Số 6 - Trang 1123-1139 - 1988
Lithospheric extension is sited, preferentially, along orogenic belts because
they have a thicker continental crust, contain structural inhomogeneities, and
suffer extensional orogenic collapse caused by body forces resulting from
isostatically compensated elevation and sharp elevation gradients. Collapse
occurs especially where rapid advective thinning of the shortened thermal
boundary conduction...
Mediterranean extension and the Africa‐Eurasia collision
Tập 19 Số 6 - Trang 1095-1106 - 2000
A number of tectonic events occurred contemporaneously in the Mediterranean
region and the Middle East 30–25 Myr ago. These events are contemporaneous to or
immediately followed a strong reduction of the northward absolute motion of
Africa. Geological observations in the Neogene extensional basins of the
Mediterranean region reveal that extension started synchronously from west to
east 30–25 Myr a...
Lateral slab deformation and the origin of the western Mediterranean arcs
Tập 23 Số 1 - 2004
The western Mediterranean subduction zone (WMSZ) extends from the northern
Apennine to southern Spain and turns around forming the narrow and tight
Calabrian and Gibraltar Arcs. The evolution of the WMSZ is characterized by a
first phase of orogenic wedging followed, from 30 Ma on, by trench retreat and
back‐arc extension. Combining new and previous geological data, new tomographic
images of the w...
Surface uplift, tectonics, and erosion of eastern Tibet from large‐scale drainage patterns
Tập 23 Số 1 - 2004
A new regional compilation of the drainage history in southeastern Tibet
suggests that the modern rivers draining the plateau margin were once
tributaries to a single, southward flowing system which drained into the South
China Sea. Disruption of the paleo‐drainage occurred by river capture and
reversal prior to or coeval with the initiation of Miocene (?) uplift in eastern
Tibet, including ∼2000 ...
Relative motion of the Nazca (Farallon) and South American Plates since Late Cretaceous time
Tập 6 Số 3 - Trang 233-248 - 1987
By combining reconstructions of the South American and African plates, the
African and Antarctic plates, the Antarctic and Pacific plates, and the Pacific
and Nazca plates, we calculated the relative positions and history of
convergence of the Nazca and South American plates. Despite variations in
convergence rates along the Andes, periods of rapid convergence (averaging more
than 100 mm/a) betwee...
Origin of the Betic‐Rif mountain belt
Tập 16 Số 3 - Trang 504-522 - 1997
In recent years, the origin of the Betic‐Rif orocline has been the subject of
considerable debate. Much of this debate has focused on mechanisms required to
generate rapid late‐orogenic extension with coeval shortening. Here we summarize
the principal geological and geophysical observations and propose a model for
the Miocene evolution of the Betic‐Rif mountain belts, which is compatible with
the ...
Geodynamics of flat subduction: Seismicity and tomographic constraints from the Andean margin
Tập 19 Số 5 - Trang 814-833 - 2000
The cause and geodynamic impact of flat subduction are investigated. First, the
1500 km long Peru flat slab segment is examined. Earthquake hypocenter data
image two morphologic highs in the subducting Nazca Plate which correlate with
the positions of subducted oceanic plateaus. Travel time tomographic images
confirm the three‐dimensional slab geometry and suggest a lithospheric tear may
bound the...
The tectonic expression slab pull at continental convergent boundaries
Tập 12 Số 2 - Trang 303-325 - 1993
Examination of five thrust belt systems developed at continental subduction
boundaries suggests that they comprise two distinct groups that display
pronounced and systematic differences in structural style, topographic
elevation, denudation, metamorphism, postcollisional convergence, and foredeep
basin geometry and facies. The distinctive geological features developed within
each thrust belt group...
