“…The second pulse of the HTP uplift occurred between 25 and 20 Ma in the northeastern, northwestern, and central TP and also in the Pamir (Sobel and Dumitru 1997;George et al 2001;Wang et al 2008;Lease et al 2011;Amidon and Hynek 2010;Zhang et al 2011;Xiao et al 2012). This uplift pulse was extensive and associated with a change in deformation mode, which is interpreted to have been related to the partial removal of lithospheric mantle under northern Tibet and subsequent weakening of the middle to lower crust (Clark and Royden 2000;Royden et al 2008;Yuan et al 2013).…”

“…25-15 Ma; Sobel and Dumitru 1997;Amidon and Hynek 2010;Zhang et al 2011). This tectonic event is considered to be the result of the initiation of south-dipping intercontinental subduction between North Pamir and the Tien Shan, which could have been triggered by breaking off of the western end of the north-dipping Indian slab .…”

Uplift of the Himalaya and Tibetan Plateau (HTP) and its linkage with the evolution of the Asian monsoon has been regarded as a typical example of a tectonic-climate linkage. Although this linkage remains unproven because of insufficient data, our understanding has greatly advanced in the past decade. It is thus timely to summarize our knowledge of the uplift history of the HTP, the results of relevant climate simulations, and spatiotemporal changes in the Indian and East Asian monsoons since the late Eocene. Three major pulses of the HTP uplift have become evident: (1) uplift of the southern and central Tibetan Plateau (TP) at ca. 40-35 Ma, (2) uplift of the northern TP at ca. 25-20 Ma, and (3) uplift of the northeastern to eastern TP at ca. 15-10 Ma. Modeling predictions suggest that (i) uplift of the southern and central TP should have intensified the Indian summer monsoon (ISM) and the Somali Jet at 40-35 Ma; (ii) uplift of the northern TP should have intensified the East Asian summer monsoon (EASM) and East Asian winter monsoon (EAWM), as well as the desertification of inland Asia at 25-20 Ma; and (iii) uplift of the northeastern and eastern TP should have further intensified the EASM and EAWM at 15-10 Ma.We tested these predictions by comparing them with paleoclimate data for the time intervals of interest. There are insufficient paleoclimate data to test whether the ISM and Somali Jet intensified with the uplift of the southern and central TP at 40-35 Ma, but it is possible that such uplift enhanced erosion and weathering that drew down atmospheric CO 2 and resulted in global cooling. There is good evidence that the EASM and EAWM intensified, and desertification started in inland Asia at 25-20 Ma in association with the uplift of the northern TP. The impact of the uplift of the northeastern and eastern TP on the Asian monsoon at 15-10 Ma is difficult to evaluate because that interval was also a time of global cooling and Antarctic glaciation that might also have influenced the intensity of the Asian monsoon.

“…[66] With regard to the geochronologic work in the Zhaxigang region, Lacassin et al [2004] and Valli et al [2007Valli et al [ , 2008 suggest that mylonites are late Oligocene in age and relate these fabrics to activity on the Karakoram Fault. Unfortunately, as documented by Zhang et al [2011], the dated mylonites were formed in the footwall of a regionally extensive detachment fault that is cut by the Karakoram fault and therefore do not relate to the Karakoram Fault itself. This observation, in conjunction with U-Pb SHRIMP dating of the Ayilari granite near Zhaxigang, from the hanging wall of the detachment [Wang et al, 2009[Wang et al, , 2012, shows the Karakoram fault was not active in the region until~13 Ma in this region.…”

New laser ablation multicollector–inductively coupled plasma–mass spectrometry and isotope dilution‐thermal ionization mass spectrometry U‐Pb ages, coupled with Sm‐Nd isotope and geochemical analysis, define the temporal and geochemical evolution of the continental lithosphere in the eastern Karakoram, India, NW Himalaya. Our analysis demonstrates that magmatism occurred between ~108 and 69 Ma and ~22 and 13 Ma. The new age data, coupled with geochemical examination of the granitoids, confirm a parallel evolution with the western Karakoram in Pakistan and supports a model of regional continental crustal thickening and related metamorphism. Middle to Late Cretaceous magmatism immediately adjacent to the Karakoram fault suggests that crustal melting and associated metamorphism are unrelated to shearing along the fault. Miocene leucogranite magmatism occurred almost exactly concomitant with the emplacement of the Baltoro batholith in Pakistan. These trans‐Karakoram leucogranites also display similar geochemical evolution trends. Our new data clearly link the leucogranites along the fault to the regional Baltoro batholith and related metamorphic complexes to the west. This supports previous work suggesting that magmatism and metamorphism were not syn‐kinematic with continental‐scale faulting. The data demonstrate that the Karakoram fault could not have accommodated lateral offset in this region prior to ~16 Ma, limiting the long‐term averaged slip rate to a maximum of ~10 mm/yr.

“…In one, the KFZ has accommodated offset of up to 250-565 km at slip rates of >10 mm/yr since initiating as early as >22 Ma [Boutonnet et al, 2012;Lacassin et al, 2004;Leloup et al, 2011;Sen et al, 2014]. In the other, the fault has accommodated offsets of less than 150 km at slip rates of <10 mm/yr, initiating after 15.68 ± 0.5 Ma [Phillips et al, 2004;Searle, 1996;Searle and Phillips, 2007;Searle et al, 1998Searle et al, , 2011Wallis et al, 2014aWallis et al, , 2014bWang et al, , 2013Zhang et al, 2011]. Estimates of both the Quaternary and present-day slip rates of the KFZ span 0-11 mm/yr [Banerjee and Bürgmann, 2002;Brown et al, 2002;Chevalier et al, 2012;Jade et al, 2004Jade et al, , 2010Robinson, 2009;Wang and Wright, 2012].…”

Spatial variation in exhumation rates across Ladakh and the Karakoram: New apatite fission track data from the Eastern Karakoram, NW India

Characterization of low-temperature cooling histories and associated exhumation rates is critical for deciphering the recent evolution of orogenic regions. However, these may vary significantly over relatively short distances within orogens. It is pertinent therefore to constrain cooling histories and hence exhumation rates across major tectonic boundaries. We report the first apatite fission track ages from the Karakoram Fault Zone in the Eastern Karakoram range, which forms part of the western margin of the Tibetan Plateau. Ten samples, from elevations of 3477-4875 m, have apatite fission track dates from 3.3 ± 0.3 Ma to 7.4 ± 1.1 Ma. The ages correspond to modeled average erosional exhumation rates of 0.67 + 0.27/À0.18 mm/yr across the Eastern Karakoram. The results are consistent with a trend northward from the Indus suture zone, across the Ladakh terrane and into the Karakoram, in which tectonic uplift associated with crustal thickening increases toward the north, raising elevation and promoting glaciation and generation of extreme relief. As a result, erosion and exhumation rates increase south to north. Present-day precipitation on the other hand varies little within the study area and on a larger scale decreases southwest to northeast across this portion of the orogen. The Eastern Karakoram results highlight the diverse patterns of exhumation driven by regional variations in tectonic response to collision along the western margin of Tibet.
