The Evolution of Foreland Basins to Steady State: Evidence from the Western Taiwan Foreland Basin

Stratigraphic Architecture and Lithofacies Analysis: Evidence for Development of the Pliocene-Holocene Taichung Foreland Basin, Central Taiwan

“…It has been recognized that the foreland sub-basins formed along the strike of the orogen (Covey 1984;Kumar et al 2003) rather than sequentially normal to the strike of the orogen. Apparently, the model proposed by Chen et al (1999) is different from that proposed by Covey (1986) for the Taiwan foreland basin. This contrast provides a room for better understanding of the evolution of Taiwan foreland basin in general and motivates us to concentrate to the refinement of the sedimentary evolution from underfilled to overfilled stages of the Taichung foreland basin in particular.…”

Fluvial geomorphic elements in modern sedimentary basins and their potential preservation in the rock record: A review

“…Foreland basins are sedimentary basins that lie between a mountain front and the adjacent craton in 222 compressional settings (Allen et al, 1986;Covey, 1986;DeCelles, 2012). We delineated geomorphic 223 elements in portions of three foreland basins-the Himalayan foreland basin in India (Fig.4), the Chaco 224…”

Tectonic Implications of Stratigraphy Architecture in Distal Part of Foreland Basin, Southwestern Taiwan

“…Under such condition, the boundaries of litho-and chronostratigraphic units are nearly parallel or even identical [75,77]. However, the situation is different for the foreland basin sequences, of which lithofacies change dramatically from that occurs in the foothills belt to that in the subsurface in the coastal plain [53,54]. The lateral lithofacies changes even appear in local area; biostratigraphic study results from the southern part of this study area by Wu et al [96] indicate that the sedimentary cycles are not coincident to the eustatic sea level fluctuation and, instead, strongly affected by tectonics.…”

“…Covey [53] was the first study on the foreland basin in western Taiwan; he suggested that the strata of the upper Pliocene to Recent in the foothills belt and coastal plain are the foreland basin sequences, which are characterized by the sedimentary facies that are shallower upward and orogenward and record the history of westward migration of the orogenic belt. Based on Suppe's [57] kinematic model of orogenic evolution, Covey [54] proposed that an underfilled foreland basin (corresponding to deeper water facies) in the early stage evolved into an overfilled one (corresponding to shallow water and continental facies) in the later stage and then entered a steady state in the following stage, i.e., the subsidence was balanced by the sediment accumulation in the basin. During cratonward migration of the orogenic belt the sequences in the proximal part of the basin were cannibalized into the mountain-building belt and a new space was created for sediment accumulation at the same time in the distal part of the basin.…”

“…All the previous studies of the foreland basin in western Taiwan assumed that the mountain-building belt and foreland basin system have been continuously migrating westward to the craton since the initiation of the Taiwan orogeny [53,54,23,50,51]; they commonly regarded the deposits in the basin as a mega-sequence unit, based on which the time-spatial variation in lithofacies has been investigated and the geometry of the basin has been reconstructed. On the other hand, Yang et al [55] analyzed the subsidence curves by Chi et al [56] and pointed out that the tectonic development of the foreland basin and its counterpart in the mountain-building belt is episodic rather than continuous as proposed by Suppe [57].…”
