The Okinawa Trough, lying between Japan and Taiwan, is a backarc basin formed by extension within the continental lithosphere behind Ryukyu trench‐arc system. Stress directions associated with two last extensional phases in southwestern Trough have been deduced from comparison analog modeling: direction of N150° for Pleistocene phase (2–0.1 Ma) N170° late Pleistocene‐Holocene (0.1–0 Ma). present‐day volcanic arc, narrow continuous feature extending to located on eastern side 80–100 km above...
Based on observations from both modem convergent margins and sandbox modeling, we examine the possible conditions favoring frontal accretion and/or basal tectonic erosion. Mean characteristic parameters (μ, μ* b λ) are used to discuss mechanical stability of 28 transects across part where Coulomb theory is applicable. Natural reveal that “typical accretionary wedges” characterized by low tapers with smooth surface slope subducting plate, convergence rates thick trench sediment, while...
Earthquake scarps associated with recent historical events have been found on the floor of Sea Marmara, along North Anatolian Fault (NAF). The MARMARASCARPS cruise using an unmanned submersible (ROV) provides direct observations to study fine‐scale morphology and geology those scarps, their distribution, geometry. are consistent diversity fault mechanisms segmentation within north Marmara extensional step‐over, between strike‐slip Ganos Izmit faults. Smaller segments pull‐apart basins...
Sandbox experiments, using a two‐dimensional and three‐dimensional approach, are used to study the deformation of margins in response seamount subduction. Successive mechanisms activated during subduction conical seamounts. First, reactivation frontal thrusts compaction accretionary wedge is observed. Then, back thrusting and, conjugate strike‐slip faulting develops above leading slope subducted seamount. The basal decollement deflected upward wake subducting high, large shadow zone behind...
Interaction between surface and tectonic processes plays a key role in the structural evolution, kinematics, exhumation of rocks orogenic wedges. The deformation patterns observed analog models show that strain partitioning has strong impact on vertical component displacement units, which return favors erosion domains important uplift. Partitioning is controlled by climate-dependent processes, including sedimentation. effects include localization deformed domains, above areas deep...

This paper reports isotopic, major and minor element geochemistry of igneous metamorphic rocks from the Kokoxili Yushu regions central eastern Tibet. The first region lies along Kunlun suture, which separates Bayan Har‐Songpan Ganze (Songpan) terrane Tarim Qaidam blocks. Two granitoids yield U‐Pb zircon dates 217 ± 10 207 3 Ma (Late Triassic), represent time emplacement, Rb‐Sr isochron 195 190 (Early Jurassic), are interpreted as cooling ages. geochemical signatures these suggest that they...
From two examples of orogenic domains, some general mechanisms significant late tectonic processes in mountain belts are characterized. The Basin and Range province the Variscan belt French Massif Central have both suffered important compressional crustal thickening, results can be observed field. Both areas covered by deep seismic profiling providing constraints on geometry a crust which has been restored to normal thickness. Late features from domains compared at different scales their...
The geology of the Jingyu basin (north Tibet) provides constraints on relationship between localized E‐W extension in Qiangtang block and strike‐slip motion along Kunlun fault. Eocene to Oligocene SW‐NE compression formed topographic relief present western Shan. Pull‐apart basins started forming ranges around 15 Ma, possibly coincident with initiation subduction Tarim‐Qaidam lithosphere under Extensional tectonism is still active, extending, as a normal fault connected was recently active....
This study examines the role of erosion on exhumation and deformation history accretionary orogens through experimental geological methods. Fault propagation, kinematics, rates in an eroded thrust wedge are analyzed scaled sandbox simulations by testing different parameters (friction, rheologic layering, sediment input/output ratio). A model Coulomb is submitted to under flux steady state conditions; that is, volume material remains equal newly accreted material, maintaining a constant...
