“…Samples TS-06 to TS-12 at the southern flank of the Kungey Range also show a normal age-elevation relationship, but AFT ages now range from 147 to 116 Ma (De Grave et al, 2013). This age-offset between the two groups of samples is probably linked to the existence of active E-W oriented faults (Abdrakhmatov et al, 2002;Buslov et al, 2003a;Delvaux et al, 2001Delvaux et al, , 2013Selander et al, 2012;Torizin et al, 2009) (Figs. 2, 6 and 9).…”

“…the Altai-Sayan; Glorie and De Grave, in press). Following these Mesozoic reactivation episodes, the study area became tectonically more stable and evidence exists that a mature peneplain developed during the Late Cretaceous-early Paleogene Bullen et al, 2001Bullen et al, , 2003De Grave et al, 2013;Delvaux et al, 2013;Glorie et al, 2010;Macaulay et al, 2014). Since the early Eocene, major structures in the southern CAOB were reactivated, which is likely a response to the continuous closure of the Tethys Ocean and associated accretions of island-arcs or continental slivers of 'Greater India' to the southern Eurasian margin (e.g.…”

Late-Paleozoic emplacement and Meso-Cenozoic reactivation of the southern Kazakhstan granitoid basement

International audienceThe Ili-Balkhash Basin in southeastern Kazakhstan is located at the junction of the actively deforming mountain ranges of western Junggar and the Tien Shan, and is therefore part of the southwestern Central Asian Orogenic Belt. The basement of the Ili-Balkhash area consists of an assemblage of mainly Precambrian microcontinental fragments, magmatic arcs and accretionary complexes. Eight magmatic basement samples (granitoids and tuffs) from the Ili-Balkhash area were dated with zircon U-Pb LA-ICP-MS and yield Carboniferous to late Permian (~ 350-260 Ma) crystallization ages. These ages are interpreted as reflecting the transition from subduction to (post-) collisional magmatism, related to the closure of the Junggar-Balkhash Ocean during the Carboniferous – early Permian and hence, to the final late Paleozoic accretion history of the ancestral Central Asian Orogenic Belt. Apatite fission track (AFT) dating of 14 basement samples (gneiss, granitoids and volcanic tuffs) mainly provides Cretaceous cooling ages. Thermal history modeling based on the AFT data reveals that several intracontinental tectonic reactivation episodes affected the studied basement during the late Mesozoic and Cenozoic. Late Mesozoic reactivation and associated basement exhumation is interpreted as distant effects of the Cimmerian collisions at the southern Eurasian margin and possibly of the Mongol-Okhotsk Orogeny in SE Siberia during the Jurassic – Cretaceous. Following tectonic stability during the Palaeogene, inherited basement structures were reactivated during the Neogene (constrained by Miocene AFT ages of ~ 17–10 Ma). This late Cenozoic reactivation is interpreted as the far-field response of the India-Eurasia collision and reflects the onset of modern mountain building and denudation in southeast Kazakhstan, which seems to be at least partially controlled by the inherited basement architecture

“…Other well-documented examples of continental lithospheric folding occur in other regions across the globe (Figure 42). Prominent examples occur in central Asia and surrounding regions (e.g., Delvaux et al, 2013;Smit et al, 2013) involving a lithosphere with thermotectonic ages from 150 Ma (Kazakh shield, Fergana and Tadjik basins, and likely Dzungarian Basin) to 400 Ma (Tarim Basin). In this area, mantle and crustal wavelengths are 360 and 50 km, respectively, with a shortening rate of $10-20 mm year À1 and 200-250 km of shortening during 10-15 My (Burov and Molnar, 1998;Burov et al, 1993).…”

“…We illustrate this by largely concentrating on the basins of central Asia, the folded lithosphere of Iberia, the NW European Platform, the Pannonian Basin, and the South Caspian Basin. (Burov and Molnar, 1998;Delvaux et al, 2013;Smit et al, 2013). In this area, the lithosphere underwent Jurassic reactivation and is characterized by relatively young thermomechanical ages (175 Ma;Burov and Molnar, 1998;Burg et al, 1994).…”

“…Preexisting thermal structure and variations in crustal thickness have played a major control on the styles and distribution of faulting in this region ( Figure 44; see also Burov and Molnar, 1998;Cobbold et al, 1993;Delvaux et al, 2013). Primary faults appear before the folding develops with a spacing that is proportional to brittle layer thickness.…”

Structure of the Bighorn Mountain region, Wyoming, from teleseismic receiver function analysis: Implications for the kinematics of Laramide shortening

et al. 2014

View full text Add to dashboard Cite

Basement-cored uplifts are observed globally and remain an enigmatic feature of plate tectonics due to the fact that, in many cases, they occur distant from a plate boundary. The Laramide Bighorn Arch in Wyoming is an archetypal basement-involved foreland arch and provides an excellent setting for the investigation of such structures. Previous studies proposed diverse arch formation models; each of which predicts a unique crustal geometry. We use high-resolution crustal imaging from teleseismic P wave receiver functions to test these models. We obtained our data from 239 three-component seismometers deployed as part of the Bighorns Arch Seismic Experiment as well as coeval regional Transportable Array stations. A sequential, two-layer thickness V P /V S (H-κ) stacking algorithm constrains sediment and crustal structure. Receiver function Common Conversion Point stacking results in 2-D transect images across the arch. Our results define an upwarp of the crust beneath the central and northern arch that extends into the Powder River Basin, north-northeast of the arch. The lack of Moho-cutting faults or a Moho geometry mirroring the arch rules out most shortening models except a crustal detachment model where shortening was accomplished by fault-propagation folding on a thrust splay ramping off a midcrustal detachment fault. The mismatch between gentle, symmetric Moho and asymmetric Laramide arch geometries and their trends suggests a pre-Laramide origin for at least a part of the Moho high. This high, perhaps in combination with a lesser degree of Laramide lithospheric buckling, may have caused emergent Laramide thrusting and thus nucleated the Bighorn Arch. Our results suggest that midcrustal detachment can form basement-involved foreland arches and suggest the hypothesis that preexisting undulations in the Moho may have nucleated individual arches.
