The tectonic uplift of the Hua Shan in the Cenozoic
Gongming Yin,Yanchou Lu,Hua Zhao,Wanlun Li,Li Li,Shilun Guo
Chinese Science Bulletin , 2001, DOI: 10.1007/BF02900632
Abstract: Six granite samples were collected from six difference elevation locations at the Hua Shan in a main ridge of the Qinling Mountain. Apatite and zircon separated from these six samples were dated by the fission track technique. An assessment of the Cenozoic uplift or exhumation rate was obtained from the altitude difference of sampling samples dated by fission track, and from the difference of fission track dates of both apatite and zircon for a sample. The preliminary results suggest that the beginning of uplift of the Hua Shan was as early as 68.2 MaBP and the uplift rates for different periods are 0.02–0.19 mm/a (from the elevation difference) or 0.12–0.16 mm/a (from two mineral fission track dates). The average uplift rate is 0.12 mm/a (from the elevation difference) or 0.14 mm/a (from two mineral fission track dates). The uplift of the Hua Shan might accelerate since (17.8±2.0) MaBP, and the average uplift rate is about 0.19 mm/a.

Abstract: The apatite (U-Th)/He dating results of 13 granitic samples collected in Nanjiang-Nanzheng transect are used to systematically study Micang Shan′s exhumation and thermo-tectonic evolution. While taking into consideration of the influence of the sample′s cooling rates and crystal sizes on (U-Th)/He closure temperatures of respective apatites, this research also quantifies the effects of topography, heat conduction, advection and production on regional geothermal gradients. The inversion results reveal a period of rapid exhumation with an average rate of ~70 m/Ma in the southern sedimentary area of Micang Shan since about 50 Ma B.P., which removed above 3 km-thick sub-surface rock in the region; the Guangwushan Complex in the middle part of Micang Shan-Hannan Uplift experienced a fast exhumation event at ~90 Ma B.P. with an exhumation rate of >75 m/Ma; the northern Hannan Uplift was exhumed to the surface with a fast rate above 40 m/Ma before ~100 Ma B.P., and then slowly with an average exhumation rate of ~10 m/Ma. The whole research region, Micang Shan-Hannan Uplift experienced a very slow exhumation with an average rate of 10~25 m/Ma during 90~50 Ma B.P.
Uplift of the Tibetan Plateau and environmental changes

Chinese Science Bulletin , 1999, DOI: 10.1007/BF03182692
Abstract: Major progress, problems, and challenges of recent investigation of the Tibetan Plateau uplift processes and resulting environmental changes are reviewed and summarized briefly, which especially covers the National Tibetan Research Projects of the Chinese Eighth (1992–1996) and Ninth (1997–2001) “Five-Year Projects”. The Tibetan Plateau uplift is a complicated multiple cyclic process. The Gangdise and Himalayas began to uplift in the Middle Eocene and Early Miocene respectively, while the main part of the Plateau merely underwent corresponding passive deformation and secular denudation, resulting in two planation surfaces. The third and also the strongest uplift involved the whole Plateau and its marginal mountains commenced at 3.6 Ma. Successive Kunlun-Huanghe movement at 1.1–0.6 Ma and Gonghe movement at 0.15 Ma raised the Plateau to its present height. The Asian monsoonal system and Asian natural environment formed in response to these tectonic uplifts.

Abstract: 哀牢山-红河断裂带范围内样品热史演化的系统构建工作偏少;部分学者往往将样品的冷却年龄简单地归因于断裂带的事件年龄,而没有考虑热扰动因素,致使以往研究结论仍然存在分歧及不合理之处.利用断裂带中高温测年资料,构建了T-t变化曲线,结合压力-温度-深度(P-T-D)变化趋势及地层恢复,对T-t变化的成因提出了较为合理的解释.中高温热史演化表明断裂带SE端(大象山段)与NW端(哀牢山段)皆经历2期冷却过程;在地层剥蚀或构造剥露作用诱导下,SE端、NW端于32~30Ma、32~22Ma分别经历第1期冷却过程,而其在26~24Ma、22~20Ma分别经历的第2期冷却过程中,由于断裂活动减弱这一因素,致使该期冷却速率明显增大(尤其是断裂带NW端).伴随着印支地块的顺时针旋转挤出,断裂带中南部左旋转换拉张构造活动向北迁移.在断裂带T-t演化的第1个阶段内,受断裂带转换拉张强度NW向减弱的影响,断裂带SE端正断活动所致的山体隆升效应明显强于NW端,致使SE端样品冷却过程较早,同时冷却速率明显偏大;而在第2个阶段,伴随着青藏高原进入中新世早期的隆升阶段,作为高原东南缘板块调节边界的哀牢山-红河断裂带其活动性由SE端开始减弱,使得冷却过程由SE端向NW端传递.
In spite of much research focused on thermal evolution historytectonic activity of the Ailao ShanRed River fault zone (ASRR) during Late OligoceneEarly Miocene, its thermal reconstruction is limited. Moreover, the related thermal disturbance factors are often ignored and the measured ages (cooling ages) are generally irrationally recognized as the timing of tectonic events in the existing studies. Combined with the pressuretemperaturedepth paths (P-T-D) and paleogeomorphology reconstruction, the T-t paths of the ASRR are constructed to explore the genesis of T-t paths and the evolutionary characteristics of the fault zone systematically. The cooling process of the metamorphic massif can be divided into two phases: for Day Nui Con Voi is 32-30Ma and 26-24Ma, while for the Ailao Shan is 32-22Ma and 22-20Ma. In the first phase, the rapid cooling may have been caused by the strata denudation or tectonic denudation, followed by the more rapid cooling of the second phase, in which the intensity weakening of the fault has been more dominant, compared with the denudation and other factors. With the clockwise rotation and extrusion of the Indochina terrane relative to the South China block, the sinistral tensile transformation zone in the south propagated northwards. Additionally, the spatial differences in the tectonic activities induced the varied cooling processes for the southeastern and northwestern part. In phase Ⅰ, the tectonic uplift in the southeastern part presented earlier and stronger than the northwestern one, with the northwestward propagation and weakening of the sinistral tensile transformation. So the cooling process of the southeastern part was much earlier and more rapid, compared with the northwestern process. In phase Ⅱ, the activity of the ASRR which acted as the boundary of the plate extrusion became weak northwards, along with a new period of Tibet uplift in early Miocene. Then the change stimulated another rapid cooling process, showing the northwestward decreasing trend
The40Ar/39Ar age record of formation and uplift of the blueschists and eclogites in the western Tianshan Mountains

Chinese Science Bulletin , 2000, DOI: 10.1007/BF02884989
Abstract: The40Ar/39Ar ages indicate that the eclogite facies rocks of the Hasiate slice in the western Tianshan Mountains were formed at the early stage of Devonian (401 Ma) and had been uplifted to the greenschist facies tectonic level in the middle stage of Devonian (381 Ma). The formation and uplift of the blueschists of the Akesayi slice are constrained to the late stage of Devonian (370-364 Ma). The different tectonic slices in the high-pressure metamorphic belt have experienced the different uplift history.

Annals of Geophysics , 1996, DOI: 10.4401/ag-3993
Abstract: Radiocarbon dating of elevated coastal phenomena along the emergent footwall of the Eliki Fault in the West- em Gulf of Corinth has established a chronology of tectonic emergence during Holocene times. The results confirm -6 m of coastal uplift over the last 3000 years at sites both immediately adjacent to, and more distant from, the offshore l'ault. Although revealing little or no spatial vm.iation along the fault, temporally the data de- fine two phases of enhanced tectonic activity (0-3000 year B.P. and pre- 7-8000 year B.P.) separated by a 4- 5000 year period of tectonic quiescence. Well documented historical surface faulting during the most recent lclive phase testify to the contribution to net uplift played by coseismic increments, but these are considered to be superimposed on significant aseismic movements. While asesismic uplift confuses the palaeoseismic .ecord, correlation of prominent notch levels with dated raised shoreline fauna provides evidence for at least 3 surface faulting events during the past 2500 years.

Abstract: The relative tectonic quiescence of the Australian continent during the Cenozoic makes it an excellent natural laboratory to study recent large-scale variations in surface topography, and processes that influence changes in its elevation. Embedded within this topography is a fluvial network that is sensitive to variations in horizontal and vertical motions. The notion that a river acts as a 'tape recorder' for vertical perturbations suggests that changes in spatial and temporal characteristics of surface uplift can be deduced through the analysis of longitudinal river profiles. We analyse 20 longitudinal river profiles around the Australian continent. Concave upward profiles in northeast Australia indicate an absence of recent surface uplift. In contrast, the major knickzones within longitudinal profiles of rivers in southwest Australia suggest recent surface uplift. Given the lack of recent large-scale tectonic activity in that region, this uplift requires an explanation. Applying an inverse algorithm to river profiles of south Western Australia reveals that this surface uplift started in the Eocene and culminated in the mid-late Neogene. The surface uplift rates deduced from this river profile analysis generally agree with independent geological observations including preserved shallow-marine sediment outcrops across the Eucla Basin and south Western Australia. We show that the interplay between global sea level and long-wavelength dynamic topography associated with south Western Australia's plate motion path over the remnants of an ancient Pacific slab is a plausible mechanism driving this surface uplift.

Abstract: The distribution of Che-Mo palaeo-uplift was delineated in detail according to the interpretation of regional seismic reflection profiles and well data.The tectonic evolution of Che-Mo palaeo-uplift can be divided into six stages,namely,initial development stage(J1s),gradual uplift stage(J2x),intense uplift stage(J2t),denudation and alteration stage(J3),embedding stage(K-E),and adjustment and orientation stage(N-Q).Based on tectonic evolution sections and facial belt distribution of Jurassic groups and truncations,the authors studied the relationship between faults and folds involved in the uplifting,which indicates that the mechanism of Che-Mo palaeo-uplift was related to the two dextral compression-shear fault-fold belts on the northern Tianshan range-front and Lunan uplift belt.

Abstract: The rate and distribution of deformation along the Qilian Mountain, on the northeastern Tibetan Plateau, is needed to understand the evolution of high topography associated with the plateau. Recently, a number of empirical studies have provided support for the contention, common to most models of fluvial incision, that rock uplift rate exerts a first-order control on the gradient of longitudinal river profiles. Along the northern Qilian Mountain, this method is used to extract information about the spatial patterns of differential rock uplift. Analysis of the longitudinal profiles of bedrock channels reveals systematic differences in the channel steepness index along the trend of the frontal ranges. Local comparisons of channel steepness reveal that lithology and precipitation have limited influence on channel steepness. Similarly, there is little evidence suggesting that channel steepness is influenced by differences in the sediment loads. We argue that the distribution of channel steepness in the Qilian Mountain is mostly the result of differential rates of rock uplift. Thus, channel steepness indices reveal a lower rock uplift rate in the eastern portion of the Qilian Mountain and a higher rate in the middle and west. The highest rates appear to occur in the middle-west portions of the range, just to the west of the Yumu Shan.
