Tectono-sedimentary evolution within the Tremp, Ainsa and Jaca basins northern Spain

前陆盆地系统是复杂的、大规模的特征，对各种变量的相互作用作出反应。虽然伸展区的模型发展得很好，但对于挤压活动占主导地位的地区来说，情况并非如此。特别是，人们对这类系统内的衰减关系(即在储集层特征方面)知之甚少。因此，研究前陆系统内构造和沉积过程的联系具有深远的重要性。始新世特雷普-潘普洛纳盆地由三个相互关联的盆地组成--特雷普盆地、AINSA盆地和雅萨盆地--它们位于比利牛斯山脉南部前陆盆地内。特雷普盆地发育为背靠型特征，而AINSA和Jaca盆地则从前渊(下始新世)演化为背靠型(上始新世)环境。这些盆地可能形成一个相互关联的沉积系统，沉积物从东部运移到西部(Tremp到Jaca)，尽管这三个盆地之间的直接联系和相互关系尚不清楚。这项研究的重点将是通过定义一系列沉积层序来批判性地研究该地区的主要体系域，然后将其整合到层序地层学模型中，该模型可以与盆地形成的控制机制有关，即与盆地所在的岩石圈板块的挠曲有关的区域沉降，以及诸如当地气候、气候和海平面的次生控制。

Foreland basin systems are complex, large-scale features that respond to interacting complexes of variables. While models for extensional areas are well developed, this is not the case for regions where compressional activity is predominant. In particular, fades relationships within such systems (i.e. in terms of reservoir characterization) is poorly understood. Thus, studies linking tectonic and sedimentation processes within foreland systems are of profound importance. The Eocene Tremp-Pamplona Basin consists of three interlinked basins - the Tremp, Ainsa and Jaca basins - which are located within the Southern Pyrenees Foreland Basin. The Tremp Basin developed as a piggyback feature, while the Ainsa and Jaca basins evolved from a foredeep (Lower Eocene) to a piggy back (Upper Eocene) setting. These basins possibly form an interlinked depostional system with sediment being transported from E to W (Tremp to Jaca), although direct linkage and correlation between the three basins is not clear. The focus of this study will be to critically examine the major systems tracts of the region by defining a series of depositional sequences which will then be integrated into a sequence stratigraphic model, which can be related to the controlling mechanisms on basin formation, namely, regional subsidence related to flexure of the lithospheric plate on which the basin is located, and secondary controls such as local Hthology, climate and eustatic sea level.
