“…The necking zone of the Eurasian continental margin offshore southwestern Taiwan comprises an east northeast trending extensional fault system [ Lee et al ., ; Lin et al ., ; Lin et al ., ; Ding et al ., ; Shi et al ., ; Tang and Zheng , ; Yang et al ., , ; Yeh et al ., ; McIntosh et al ., ] that can be traced from the margin in the Taiwan Strait across the Coastal Plain [ Chang , , ; Lin et al ., ; Yang et al ., ] and into the fold‐and‐thrust belt where some of its faults are being reactivated [ Suppe , ; Mouthereau et al ., , ; Mouthereau and Lacombe , ; Yang et al ., , ; Rodriguez‐Roa and Wiltschko , ; Alvarez‐Marron et al ., ; Camanni et al ., ]. In particular, the fault system along the upper part of the necking zone, the Yichu (or A), Meishan, and B faults (Figures and ), which also comprise the northern bounding faults of the Tainan Basin [ Yang et al ., ; Lee et al ., ; Lin et al ., ], are of particular importance.…”

“…Lin et al ., ; Li et al ., ; Ding et al ., ]. These basement highs and lows result in important changes in thickness of the Miocene and Pleistocene sediments [e.g., Hsiao , ; Shaw , ; Yang et al ., ]. The changes in sediment thickness from one thrust sheet to another has led to the interpretation of extensional fault reactivation in the fold‐and‐thrust [e.g., Suppe , ; Rodriguez‐Roa and Wiltschko , ; Yang et al ., , ; Alvarez‐Marron et al ., ].…”

How the structural architecture of the Eurasian continental margin affects the structure, seismicity, and topography of the south central Taiwan fold‐and‐thrust belt

Studies of mountain belts worldwide show that along‐strike changes are common in their foreland fold‐and‐thrust belts. These are typically caused by processes related to fault reactivation and/or fault focusing along changes in sedimentary sequences. The study of active orogens, like Taiwan, can also provide insights into how these processes influence transient features such as seismicity and topography. In this paper, we trace regional‐scale features from the Eurasian continental margin in the Taiwan Strait into the south central Taiwan fold‐and‐thrust belt. We then present newly mapped surface geology, P wave velocity maps and sections, seismicity, and topography data to test the hypothesis of whether or not these regional‐scale features of the margin are contributing to along‐strike changes in structural style, and the distribution of seismicity and topography in this part of the Taiwan fold‐and‐thrust belt. These data show that the most important along‐strike change takes place at the eastward prolongation of the upper part of the margin necking zone, where there is a causal link between fault reactivation, involvement of basement in the thrusting, concentration of seismicity, and the formation of high topography. On the area correlated with the necking zone, the strike‐slip reactivation of east northeast striking extensional faults is causing sigmoidal offset of structures and topography along two main zones. Here basement is not involved in the thrusting; there is weak focusing of seismicity and localized development of topography. We also show that there are important differences in structure, seismicity, and topography between the margin shelf and its necking zone.

“…In a fault-bounded foreland basin like the Chaiwopu Basin, the investigations of both tectono-sedimentary evolution and geomorphic expression of tectonic deformation are crucial to reveal the history of tectonic deformation of the basin [e.g., Burbank, 1992;Burbank et al, 1996;Bullen et al, 2003;Chen et al, 2007;Heermance et al, 2007;Lu et al, 2010a;Burbank and Anderson, 2011;Vandenberghe et al, 2011;Yang et al, 2012Yang et al, , 2014. Certainly, such analysis should be placed in a robust temporal framework.…”

“…In foreland basins, detailed sedimentological and geomorphological investigations are helpful to understand the tectonic evolution of the basin [e.g., Molnar et al, 1994;Burbank et al, 1996;Burchfiel et al, 1999;Burbank and Anderson, 2011;Yang and Li, 2011;Yang et al, 2014;Thompson et al, 2015]. The main aim of this work is to develop a chronology of the late Cenozoic deformation in the southern Chaiwopu Basin of the northern Chinese Tian Shan foreland by integrating stratigraphic and geomorphic data.…”

Basinward propagation of fold and thrust belts is a crucial geological process accommodating Cenozoic crustal shortening within the India‐Eurasia collision zone. Anticlinal growth strata in the southern Chaiwopu Basin (a piggyback basin) of the northern Chinese Tian Shan foreland record basinward encroachment of the Tian Shan along the Junggar Frontal Thrust Fault. A new magnetostratigraphic section constrains the onset of syntectonic growth strata at circa 6.4 Ma and suggests synchronous basinward thrusting and propagation of the Tian Shan. The intense alluviation in the southern Chaiwopu Basin ceased at circa 0.55 Ma due to significant anticlinal growth and its resultant river incision. More recent anticlinal growth and deformation during the late Quaternary are revealed by folded river terraces developing across the anticline. The terrace height profile indicates that terrace T1H has been vertically offset about 0.6 m by thrust faulting since its formation at about 7 Ka. The stratigraphic and geomorphic data presented in this work are helpful to understand the initiation of thrust‐related folding, as well as aggradation and subsequent incision, in foreland basins of the Tian Shan in relation to the India‐Asia collision.

“…These shallow-marine slope basin sediments are derived from the exposed accretionary prism to the north (Huang et al, 2006). Planktonic foraminiferal assemblage recovered from the basal part of the slope basin (Maanshan Formation in the West Hengchun Hill) suggests an age of 4.3-3.6 Ma (Early Pliocene; Cheng and Huang, 1975;Huang et al, 2006), consistent with the onset of foreland sedimentation in the southern part of the Western Foothills (Yang et al, 2014).…”
