The Central European Basin is a classic area of salt tectonics, characterized by heterogeneous structural evolution and complex
salt movement history. We studied an area on its SW margin, based on prestack depth-migrated 2D and 3D seismic data. We use
seismic interpretation and retro-deformation to obtain a better understanding of salt tectonics, structural control, and sedimentary
response in this region. The first phase of salt tectonic evolution started with two main events of NW–SE extension and rafting
in the Triassic before the Upper Bunter and before the Upper Muschelkalk. Rafting was accompanied by first salt diapirism
and an increased sedimentary thickness adjacent to the salt structure. After salt supply ceased updip to the salt structure,
a mini-basin grew in the intra-raft area. This sedimentary differential loading caused salt movement and growth of a pillow
structure basinward. The second phase of salt movement was initiated by the formation of a NNW–SSE striking basement graben
in the Middle Keuper that triggered reactive diapirism, the breakthrough of the pillow’s roof and salt extrusion. The following
downbuilding process was characterized by sedimentary wedges with basal unconformities, onlap structures and salt extrusions
that ceased in the Jurassic. The third and latest phase of salt tectonic evolution was activated in the Late Cretaceous to
Lower Tertiary by compressional tectonics indicated by salt rise and a small horizontal shortening of the diapir. The interpreted
salt tectonic processes and the resulting geometries can now be better tied in with the regional heterogeneous framework of
the basin.

The NW–SE-striking Northeast German Basin (NEGB) forms part of the Southern Permian Basin and contains up to 8 km of Permian to Cenozoic deposits. During its polyphase evolution, mobilization of the Zechstein salt layer resulted in a complex structural configuration with thin-skinned deformation in the basin and thick-skinned deformation at the basin margins. We investigated the role of salt as a decoupling horizon between its substratum and its cover during the Mesozoic deformation by integration of 3D structural modelling, backstripping and seismic interpretation. Our results suggest that periods of Mesozoic salt movement correlate temporally with changes of the regional stress field structures. Post-depositional salt mobilisation was weakest in the area of highest initial salt thickness and thickest overburden. This also indicates that regional tectonics is responsible for the initiation of salt movements rather than stratigraphic density inversion.Salt movement mainly took place in post-Muschelkalk times. The onset of salt diapirism with the formation of N–S-oriented rim synclines in Late Triassic was synchronous with the development of the NNE–SSW-striking Rheinsberg Trough due to regional E–W extension. In the Middle and Late Jurassic, uplift affected the northern part of the basin and may have induced south-directed gravity gliding in the salt layer. In the southern part, deposition continued in the Early Cretaceous. However, rotation of salt rim synclines axes to NW–SE as well as accelerated rim syncline subsidence near the NW–SE-striking Gardelegen Fault at the southern basin margin indicates a change from E–W extension to a tectonic regime favoring the activation of NW–SE-oriented structural elements. During the Late Cretaceous–Earliest Cenozoic, diapirism was associated with regional N–S compression and progressed further north and west. The Mesozoic interval was folded with the formation of WNW-trending salt-cored anticlines parallel to inversion structures and to differentially uplifted blocks. Late Cretaceous–Early Cenozoic compression caused partial inversion of older rim synclines and reverse reactivation of some Late Triassic to Jurassic normal faults in the salt cover. Subsequent uplift and erosion affected the pre-Cenozoic layers in the entire basin. In the Cenozoic, a last phase of salt tectonic deformation was associated with regional subsidence of the basin. Diapirism of the maturest pre-Cenozoic salt structures continued with some Cenozoic rim synclines overstepping older structures. The difference between the structural wavelength of the tighter folded Mesozoic interval and the wider Cenozoic structures indicates different tectonic regimes in Late Cretaceous and Cenozoic.We suggest that horizontal strain propagation in the brittle salt cover was accommodated by viscous flow in the decoupling salt layer and thus salt motion passively balanced Late Triassic extension as well as parts of Late Cretaceous–Early Tertiary compression. 相似文献

The study provides a regional seismic interpretation and mapping of the Mesozoic and Cenozoic succession of the Lusitanian Basin and the shelf and slope area off Portugal. The seismic study is compared with previous studies of the Lusitanian Basin. From the Late Triassic to the Cretaceous the study area experienced four rift phases and intermittent periods of tectonic quiescence. The Triassic rifting was concentrated in the central part of the Lusitanian Basin and in the southernmost part of the study area, both as symmetrical grabens and half-grabens. The evolution of half-grabens was particularly prominent in the south. The Triassic fault-controlled subsidence ceased during the latest Late Triassic and was succeeded by regional subsidence during the early Early Jurassic (Hettangian) when deposition of evaporites took place. A second rift phase was initiated in the Early Jurassic, most likely during the Sinemurian–Pliensbachian. This resulted in minor salt movements along the most prominent faults. The second phase was concentrated to the area south of the Nazare Fault Zone and resulted here in the accumulation of a thick Sinemurian–Callovian succession. Following a major hiatus, probably as a result of the opening of the Central Atlantic, resumed deposition occurred during the Late Jurassic. Evidence for Late Jurassic fault-controlled subsidence is widespread over the whole basin. The pattern of Late Jurassic subsidence appears to change across the Nazare Fault Zone. North of the Nazare Fault, fault-controlled subsidence occurred mainly along NNW–SSE-trending faults and to the south of this fault zone a NNE–SSW fault pattern seems to dominate. The Oxfordian rift phase is testified in onlapping of the Oxfordian succession on salt pillows which formed in association with fault activity. The fourth and final rift phase was in the latest Late Jurassic or earliest Early Cretaceous. The Jurassic extensional tectonism resulted in triggering of salt movement and the development of salt structures along fault zones. However, only salt pillow development can be demonstrated. The extensional tectonics ceased during the Early Cretaceous. During most of the Cretaceous, regional subsidence occurred, resulting in the deposition of a uniform Lower and Upper Cretaceous succession. Marked inversion of former normal faults, particularly along NE–SW-trending faults, and development of salt diapirs occurred during the Middle Miocene, probably followed by tectonic pulses during the Late Miocene to present. The inversion was most prominent in the central and southern parts of the study area. In between these two areas affected by structural inversion, fault-controlled subsidence resulted in the formation of the Cenozoic Lower Tagus Basin. Northwest of the Nazare Fault Zone the effect of the compressional tectonic regime quickly dies out and extensional tectonic environment seems to have prevailed. The Miocene compressional stress was mainly oriented NW–SE shifting to more N–S in the southern part. 相似文献

A dense grid of multichannel high-resolution seismic sections from the Bay of Kiel in the western Baltic Sea has been interpreted
in order to reveal the Mesozoic and Cenozoic geological evolution of the northern part of the North German Basin. The overall
geological evolution of the study area can be separated into four distinct periods. During the Triassic and the Early Jurassic,
E–W extension and the deposition of clastic sediments initiated the movement of the underlying Zechstein evaporites. The deposition
ceased during the Middle Jurassic, when the entire area was uplifted as a result of the Mid North Sea Doming. The uplift resulted
in a pronounced erosion of Upper Triassic and Lower Jurassic strata. This event is marked by a clear angular unconformity
on all the seismic sections. The region remained an area of non-deposition until the end of the Early Cretaceous, when the
sedimentation resumed in the area. Throughout the Late Cretaceous the sedimentation took place under tectonic quiescence.
Reactivated salt movement is observed at the Cretaceous Cenozoic transition as a result of the change from an extensional
to compressional regional stress field. The vertical salt movement influenced the Cenozoic sedimentation and resulted in thin-skinned
faulting. 相似文献

A 3D structural model for the entire southwestern Baltic Sea and the adjacent onshore areas was created with the purpose to analyse the structural framework and the sediment distribution in the area. The model was compiled with information from several geological time-isochore maps and digital depth maps from the area and consists of six post-Rotliegend successions: The Upper Permian Zechstein; Lower Triassic; Middle Triassic; Upper Triassic–Jurassic; Cretaceous and Cenozoic. This structural model was the basis for a 3D backstripping approach, considering salt flow as a consequence of spatially changing overburden load distribution, isostatic rebound and sedimentary compaction for each backstripping step in order to reconstruct the subsidence history in the region. This method allows determination of the amount of tectonic subsidence or uplifting as a consequence of the regional stress field acting on the basin and was followed by a correlation with periods of active salt movement. In general, the successions above the highly deformed Zechstein evaporites reveal a thickening trend towards the Glückstadt Graben, which also experienced the highest amount of tectonic subsidence during the Mesozoic and Cenozoic. Two periods of accelerating salt movement in the area has been correlated with the E–W directed extension during the Late Triassic–Early Jurassic and later by the Late Cretaceous–Early Cenozoic inversion, suggesting that the regional stress field plays a key role in halokinesis. The final part of this work dealt with a neotectonic forward modelling in an attempt to predict the future topography when the system is in a tectonic equilibrium. The result reveals that many of the salt structures in the region are still active and that future coastline will run with a WNW–ESE trend, arguing that the compressional stresses related to the Alpine collision are the prime factor for the present-day landscape evolution. 相似文献

地层不整合接触是研究地质发展历史和鉴定地壳运动特征的重要依据。通过大范围露头尺度和填图尺度不整合面的识别,结合不同时代地层沉积体系的特征及构造变形样式的对比研究,发现东昆仑造山带东段晚古生代—中生代地层由底到顶共发育有4个不同类型的不整合面,分别是上二叠统格曲组与上石炭统浩特洛哇组之间的角度不整合面、中三叠统希里可特组与闹仓坚沟组之间的微角度不整合面、上三叠统八宝山组与下伏不同时代地层之间的角度不整合面、下侏罗统羊曲组与上三叠统八宝山组之间的平行不整合面。这几个不同时代的不整合面分别代表了东昆仑东段晚古生代—中生代地质演化时期中特定的构造事件。其中,格曲组与浩特洛哇组角度不整合关系代表东昆仑造山带南缘阿尼玛卿—布青山古特提斯洋晚二叠世开始向北俯冲的构造事件;希里可特组与闹仓坚沟组微角度不整合关系与陆(弧)陆局部差异性初始碰撞的洋陆转换构造事件密切相关;八宝山组与下伏不同时代地层角度不整合关系是东昆仑地区分布较广、意义重大的一个不整合面,代表中三叠世晚期—晚三叠世早期东昆仑地区陆(弧)陆全面碰撞的主造山构造事件,同时该期碰撞造山事件铸就了东昆仑及其周缘地区的基本构造格架。羊曲组与八宝山组之间平行不整合面则与晚三叠世晚期—早侏罗世早期陆内演化过程中地壳垂向抬升事件相关。这些不整合面的厘定及其代表的相应构造事件对于合理建立东昆仑地区晚古生代—中生代构造演化过程具有重要意义。 相似文献

小秦岭金矿田位于华北克拉通南缘,同时也是秦岭复合型造山带的北缘组成部分。这里是我国第二大黄金产地,大规模金的成矿作用形成于早白垩世岩石圈大规模减薄的区域伸展构造背景。此外,越来越多的同位素年代学数据显示区内还存在三叠纪的成矿事件发育钼、铅、铀、铌等与岩浆热液活动密切相关的多金属矿床,主要分布在小秦岭的南北边缘。目前,对于三叠纪多金属成矿作用的构造背景研究尚属薄弱,还没有直接对有关的构造变形开展过专题研究。为此,我们对小秦岭金矿田东端边缘的构造带进行构造观察和测量,并采用~(40) Ar-~(39) Ar年代学方法厘定变形时限,揭示三叠纪成矿事件的构造背景,为深入认识区内三叠纪多金属成矿作用特征和规律提供构造证据。研究表明,小秦岭金矿田三叠纪成矿事件发生于晚三叠世的伸展构造背景,可以划分为两个阶段早期(221～216Ma)是在碰撞向后碰撞转折阶段的重力滑脱构造环境中,发育火成碳酸岩型钼铅、铀铌铅多金属矿床;晚期(214～203Ma)是在后碰撞阶段由俯冲板片断离或岩石圈拆沉作用等深部过程导致的区域伸展构造环境中,发育石英脉型和斑岩型钼矿床。小秦岭中生代晚三叠世和早白垩世两期成矿事件都是在伸展构造背景中的构造-岩浆-流体活动的产物。 相似文献

The Sulu orogenic belt (SOB) separates the North and South China blocks in East Asia and formed during Triassic continent-continent collision. However, late Mesozoic post-collisional exhumation is poorly understood due to lack of surface evidence for Paleo-Pacific subduction and associated effects. This paper interprets the tectonic history of the SOB using detrital zircon age data from Early Cretaceous sedimentary units along with previously published geochronologic and geochemical data to reconstruct sedimentological and tectonic history. Detrital zircon age distributions obtained from sedimentary units include a 2.0 Ga subpopulation that appears only in turbidite units to the southeast. This sediment probably derived from the Yangtze Block. Terrestrial facies from the Jiao-Lai basin to the northwest appear to derive from the North China Block. Geochronologic and geochemical data indicate that Early Cretaceous, post-collisional volcanism was compositionally bimodal (mafic-felsic) with associated intrusive activity that peaked at 120 Ma. Seismic images of northerly regions of the study area indicate this occurred in an extensional setting. Sedimentary facies and field structural analyses revealed an unconformity interpreted to reflect rapid uplift with NW–SE compression to the south. Given observed sinistral movement along the Tan-Lu fault, we interpret northwest and southeast regions of the SOB as experiencing transtensional and transpressional tectonics, respectively, driven by continuous subduction of the Paleo-Pacific Plate. Intrusion of the Late Yanshannian granitoids marked the final formational stage of this unique tectonic setting. 相似文献

Normal faulting and the deep subsurface flow of salt are key processes controlling the structural development of many salt-bearing sedimentary basins. However, our detailed understanding of the spatial and temporal relationship between normal faulting and salt movement is poor due to a lack of natural examples constraining their geometric and kinematic relationship in three-dimensions. To improve our understanding of these processes, we here use 3D seismic reflection and borehole data from the Egersund Basin, offshore Norway, to determine the structure and growth of a normal fault array formed during the birth, growth and decay of an array of salt structures. We show that the fault array and salt structures developed in response to: (i) Late Triassic-to-Middle Jurassic extension, which involved thick-skinned, sub-salt and thin-skinned supra-salt faulting with the latter driving reactive diapirism; (ii) Early Cretaceous extensional collapse of the walls; and (iii) Jurassic-to-Neogene, active and passive diapirism, which was at least partly coeval with and occurred along-strike from areas of reactive diapirism and wall collapse. Our study supports physical model predictions, showcasing a three-dimensional example of how protracted, multiphase salt diapirism can influence the structure and growth of normal fault arrays. 相似文献
