9805076 Hoisch The problem of the relationship between the foreland and the crystalline hinterland in mountains belts in general, and in the Sevier orogenic belt in particular is a significant and long standing problem. This study focuses on rocks of the hinterland, and will employ a variety of techniques to extract information on the timing of loading and of exhumation of these high grade metamorphic rocks. The study will reveal the types of processes that occur in the lower crust of a hinterland, in particular, include the absolute dating of these processes. The larger significance is that with this information, the events in the lower crust of the hinterland can be correlated in time with sedimentary events in the upper crust of the foreland.

小行星9805076 一般来说，在山区地带，特别是在塞维尔造山带中，前陆和结晶腹地之间的关系问题是一个重要而长期存在的问题。 这项研究的重点是内地的岩石，并将采用各种技术来提取信息的加载时间和这些高级变质岩的折返。这项研究将揭示发生在内陆地区下地壳的过程类型，特别是包括这些过程的绝对定年。 更重要的是，有了这些信息，内陆下地壳的事件可以与前陆上地壳的沉积事件在时间上相关联。
