“…Bourgeois et al (1997) restored deformation pattern within the Tajik basin, suggesting a rotated indenter whereas Leith and Alvarez (1985) suggest that the Tajik FTB is pressed against the slope of the Gissar Range. Brookfield and Hashmat (2001) suggest that westward directed gravitational gliding of the foldand-thrust belt might be triggered by the northward movement of the Pamir. Using the classification of Macedo and Marshak (1999), basin controlled vs. indenter controlled, the Tajik basin would be classified as an indenter controlled basin, because trend lines converges at the apex of the salient, which is to find in the north of the Pamir.…”

Editor: Y. Ricard Keywords:4D analogue experiments two indenter tectonics particle image velocimetry fold-and-thrust belts Tajik basin Pamir Scaled analogue experiments are used to investigate the indentation of two basement blocks into a sedimentary basin and the formation of a fold-and-thrust belt. The experimental set-up has two adjacent indenters moving in parallel with a velocity difference. The slow indenter moves with a relative velocity ranging from 40 to 80% of that of the fast one. In a first experimental series, quartz sand and low-friction glass beads represent the sediment stack and its basal detachment, respectively; silicone oil simulates a viscous detachment in the second series of experiments. The surface evolution and the spatio-temporal strain distribution are derived from particle image velocimetry (PIV). Together with the 3D finite structure derived by cutting the models at the end of each experiment, this allows the analysis of the structural evolution of the experimental wedges. Thrusting wedge development depends crucially on the relative velocity: when the slow indenter moves with a velocity of more than 55% of the fast indenter, a single curved thrust wedge develops. The wedge becomes decoupled along strike-slip zone at large velocity differences, i.e. when the slow indenter moves slower than 55% of the faster indenter. Consequently the thrust front is strongly curved at high (55-60%) and smoothly curved at low velocity differences (70-80%); in all cases curvature increases during indentation. Along the most strongly curved portion of the thrust wedge, the transfer zone rises, particle rotation and material transport oblique to the indentation direction occur directed toward the front of the slow indenter. Thrusting cycles are timed by the fast indenter and influence thrusting in front of the slow indenter. Thrusts nucleate in front of the fast indenter wedge and propagate laterally to the slow indenter front. This implies distant effects of wedge growth active hundreds of kilometers along-strike of orogens. Silicone oil as a detachment induces a low-angle wedge, which is less curved than in the glass beads experiments, and shows variable thrust vergence with fore-and back-thrusts. We compare our experimental results with the curved fold-and-thrust belts of the Tajik basin in front of the Hindu-Kush and Pamir indenters; our results are able to explain several first-order features.

“…In Late Permian-Triassic (possibly Late Triassic/Early Jurassic [56]) the Iranian Block collided with the southern margin of Eurasia, and the Paleotethys Ocean was closed [29,57,58]. A series of structural faults formed in the collision event separate the basement of the basin into numerous paleo-uplifts and graben structures [59][60][61][62]. Hereafter, the Amu-Darya Basin entered the development stage of rift basin [63] and a period of stable settlement.…”

Abstract:The Calloviane-Oxfordian carbonates in the northeastern Amu Darya Basin of southeastern Turkmenistan are composed of medium-to thick-bedded, mostly grainy limestones with various skeletal (bivalves, brachiopods, echinoderms, foraminifera, corals, and sponge) and non-skeletal grains (intraclasts, ooids and peloids). Two facies zones, six standard facies belts and some microfacies types were recognized, and sedimentary model "carbonate ramp-rimmed platform" was proposed and established that can be compared with the classical carbonate sedimentary models. In this model, favorable reservoirs not only developed in the intraplatform shoal of open platform, or reef and shoal on the platform margin, but also in the patch reefs, shoal and mound facies on the upper slope. The reservoir's pore space is dominated by intergranular and intragranular pores and fissure-pore reservoirs exist with medium porosity and medium to low permeability. Sedimentary facies and diagenetic dissolution are the key controlling factors for the development of high-quality reservoirs.

The geological evolution of Central Asia commenced with the evolution of a complex Precambrian–Palaeozoic orogen. Cimmerian blocks were then accreted to the southern margin during the Mesozoic, leading to tectonic reactivation of older structures and discrete episodes of basin formation. The Indian and Arabian blocks collided with Asia during the Cenozoic, leading to renewed structural reactivation, intracontinental deformation and basin development. This complex evolution resulted in the present-day setting of an elongated Tien Shan range flanked by large Mesozoic–Cenozoic sedimentary basins with smaller intramontane basins distributed within the range. The aim of this volume is to present multidisciplinary results and reviews from research groups in Europe and Central Asia that focus on the western part of the Tien Shan and some of the large sedimentary basins in that area. These works elucidate the Late Palaeozoic–Cenozoic tectono-sedimentary evolution of the area. Emphasis is placed on the collision of terranes and/or continents and the ensuing fault reactivation; the impact of changes in climate on the sedimentation is also examined.
