The Coast Range Ophiolite in Southwestern Oregon and Comparison to the Josephine Ophiolite: New Constraints for the Mesozoic Evolution of the North American Continental Margin

9706798哈珀，据信已在海底形成的蛇绿岩组合的合并是一个顽固的问题，仍然难以解决。然而，它们中的一些可以用来重建它们形成的海洋环境。在这种情况下，它们可以极大地有助于理解导致它们并入上地壳沉积组合的构造过程。哈珀的研究使用了地球化学、地质年代学、沉积物源和田野结构，这是一项定义明确的研究，将在俄勒冈州西南部的海岸山脉蛇绿岩中解决这些问题。他的分析方法多种多样，结果将与这个蛇绿岩序列的起源以及它与加州几个构造带上的其他蛇绿岩的关系有关。

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.
