Structure and Evolution of an Active Thrust Front: Eastern Precordillera, Argentine Andes

逆冲断层前缘位于 带和前陆盆地 我们发现的独特结构 在这些区域（相对的顶点和三角形区域）中， 冲断带向前陆的正常扩展， 它们的形成可能是因为冲断带无法继续移动 往克拉通的方向 该项目将检查地下和 从阿根廷西部的Precordillera的表面数据， 冲断前缘暴露良好， 可用于再加工。 结果将有助于解决起源 以及理解 总的来说是逆冲带。

Thrust fronts are located at the interface between thrust belts and foreland basins. The unique array of structures found in these zones (opposing vergencies and triangle zones) may be due to normal propagation of the thrust belt towards the foreland or they may be developed because the thrust belt could move no farther towards the craton. This project will examine subsurface and surface data from the Precordillera of western Argentina where a thrust front is well exposed, and considerable seismic data is available for reprocessing. Results will help resolve the origin of thrust front structures and in understanding the mechanics of thrust belts in general.
