The CL images, LA-ICP-MS in situ trace elements analysis, and U-Pb dating for zircons indicate that the metamorphic ages of the sillimanite-garnet-biotite gneiss and the garnet-amphibole gneiss from eastern Taxkorgan of the Western Kunlun Mountains are 220±2 and 220±3 Ma respectively, and their protolith ages are younger than 253±2 and 480±8 Ma respectively. Two samples were collected at the same outcrops with HP mafic granulite and HP pelitic granulite. Mineral assemblage of the sillimanite-garnet-biotite gneiss (Grt+Sill+Per+Q) is consistent with that of HP pelitic granulite at early high amphibolite-granulite facies stage. Mineral assemblage of the garnet-amphibole gneiss (Grt+Amp+Pl+Q) is consistent with retro-metamorphic assemblage of HP mafic granulite at amphibolite facies stage. The dating results suggest that these HP granulites underwent peak metamorphism at 220±2 to 253±2 Ma. Thus, the Kangxiwar tectonic zone was probably formed by subduction and collision of the Paleo-Tethys Ocean during Indosinian. Protolith ages of the two samples, together with previously published U-Pb zircon dating age, suggest that the sillimanite-garnet schist-quartzite unit is a late Paleozoic unit, not a part of the Paleoproterozoic Bulunkuole Group.

“…THE TIBETAN PLATEAU is composed of several terranes of various origins, which were accreted to the southern margin of Laurasia during consumption of the Tethyan Ocean (Chang et al, 1986(Chang et al, , 1989Dewey et al, 1988). The Kunlun Mountain range lies along the northern margin of the Plateau, and is divided into West and East Kunlun, extending westward to the North Pamir Range of Afghanistan (Debon et al, 1987).…”

The West Kunlun contains important information about the early evolutionary history of the Tibetan Plateau. Single-grain zircon U-Pb dating and systematic geochemical analyses were conducted on representative granitic plutons from the Kudi area. The earliest Paleozoic magmatism (471 ± 5 Ma) possesses characteristics of volcanic-arc granites, indicating that Proto-Tethys started to close in the Mid-Ordovician. An arc-continent collision occurred in the Late Ordovician, corresponding to the closure of Proto-Tethys. Following the collision, extensional deformation began in the Early Devonian and gave rise to a post-dynamic, A-type North Kudi Pluton (405 ± 2 Ma) and coeval lamprophyre dikes. Extension was pervasive throughout the whole Kunlun orogenic belt, and was responsible for Devonian to Early Permian magmatic quiescence. The reoccurrence of magmatism in the West Kunlun took place in the Early Permian, when Paleo-Tethys started to be consumed, and a new subduction zone developed in the West Kunlun. Paleo-Tethys closed by the Late Triassic (214 ± 1Ma), and led to rapid uplift and voluminous post-collisional granites.

“…The asymmetry of the Bangong/Nujiang basin is in support of the strike-slip basin interpretation (compare Mitchell and Reading 1989;Ben-Avraham 1992;BenAvraham and Zoback 1992 Kidd et al 1988, their Fig. 9) and extent of the Bangong/Nujiang zone (BNZ) Lhasa block which occur along the line of the Qiling Co Lake and Coqen (north central Lhasa block) reflect the initial opening (Chang et al 1989). Permian volcanism within the Lhasa and Qiangtang blocks was attributed to extensional tectonics of back-arc or rift affinities (Leeder et al 1988).…”

“…We attribute the younger alternations to uplift tendencies related to the late Triassic Songpan-Ganzi terrane/Qiangtang block accretion which occurred north of the Qiangtang block . Only from the late Triassic on were major facies differences recognized to the north and south of the Bangong/Nujiang zone by Chang et al (1989). They concluded that the Lhasa and Qiangtang blocks formed one continental terrane until the late Triassic when the Bangong/Nujiang basin opened between them.…”

Our literature studies show that the thermal regime along continental strike-slip rifts is inconspicuous and that they are "low-volcanicity rifts" at best. Along with that, young continental strike-slip rifts exhibit no signs of major thermally controlled doming. We suggest that the larger the strike-slip component of a rift is, the less likely major thermal doming is causally associated with the rift zone. Since vertical lithosphere movements are reflected in the stratigraphic record of a rifted area, different rift modes (strike-slip, dip-slip) may be distinguished by analyzing the relevant sequences. Two ancient and especially suitable strike-slip rift margins in Tethyan mountain belts, the Bangong/Nujiang zone of Tibet and the South Penninic zone of the Alps, were analyzed with regard to their uplift history. The results confirm recent regional rift models which indicate in both cases that rifting was dominated by strike-slip. The stratigraphic approach may provide significant clues as to the mode of paleorifting when structural data are unavailable.
