Many major mountain systems of the world are in part the result of large scale compression of the crust in what are termed, fold-and-thrust belts. The style of formation of such belts is controversial. One school of thought reckons that they form in a manner similar to deforming snow ahead of a plow ("critical taper model"), whereas the other advocates formation by the compression of a beam. This project proposes an experiement to test these two hypotheses using field relations in the Pyrenees Mountains of Spain. This will be an important experiment because the method of geometric reconstruction commonly used to model deformed terranes, especially hydrocarbon-bearing reservoirs, depend in large part on the assumption of deformational style.

世界上许多主要的山系都是 地壳大规模挤压的结果 被称为褶皱冲断带 形成的风格 这类腰带是有争议的。 一种学派 认为它们的形成方式类似于雪的变形 前犁（“临界锥度模型”），而另一个 主张通过光束的压缩来形成。 这 项目提出了一个实验来验证这两个假设 在西班牙的比利牛斯山脉使用领域关系。 这将是一个重要的实验，因为 几何重建通常用于模型变形 油气藏，特别是含油气藏， 在很大程度上是基于变形样式的假设。
