9706798 Harper The incorporation of ophiolotic rock assemblages that are believed to have formed on the ocean floor is a tenacious problem that continues to defy solution. However, some of them can be used to reconstruct the oceanic environment in which they formed. In such cases they can contribute greatly to understanding the tectonic processes that lead to their incorporation into upper crustal sedimentary assemblages. Harper's study using geochemistry, geochronology, sedimentary provenance and field structure is a well defined one that will address these questions in the Coast Range ophiolites in southwestern Oregon. His analytical methods are varied, and the results will bear on the origin of this ophiolite sequence and on its relationship to other ophiolites in several structural belts in California.

9706798哈珀 据信是在海底形成的蛇绿岩组合的合并是一个顽固的问题，继续无法解决。 然而，其中一些可以用来重建它们形成的海洋环境。在这种情况下，它们可以大大有助于了解导致它们并入上地壳沉积组合的构造过程。哈珀的研究使用地球化学，地质年代学，沉积物源和现场结构是一个明确的，将解决这些问题在海岸山脉蛇绿岩在西南部俄勒冈州。他的分析方法多种多样，其结果将对该蛇绿岩序列的成因及其与加州几个构造带中其他蛇绿岩的关系产生影响。
