U.S.-Poland Geophysical Research on Texture Components for Low Crystal Symmetries

这项美国-波兰研究的主要目标是加州大学伯克利分校的汉斯-鲁道夫·温克博士，波兰科学院金属研究所的Jan Pospiech博士将通过将Pawlich-Pospiech （PP）断层扫描算法扩展到低晶和三斜样品对称，来推进变形材料的定量纹理分析。本文选择的重点材料是石英，它在地壳中具有重要的构造意义。它的结构在地质条件下也有很大的不同。研究人员计划一起测量来自不同古典地区的变形石英岩的极形，并用PP方法编制odf目录。研究结果将为石英结构的地球物理变形史提供更定量的解释。这个地球物理学项目实现了推进科学知识的计划目标，使美国和波兰的主要研究人员能够在平等、互惠的基础上，在共同感兴趣和有能力的基础科学研究领域结合互补的努力和能力。互惠互利。

The primary objective of this U.S.-Poland research between Dr. Hans-Rudolf Wenk of the University of California, Berkeley, and Dr. Jan Pospiech of the Polish Academy of Sciences' Institute for Metals Research is to advance quantitative texture analysis of deformed materials by extending the tomography algorithm of Pawlich-Pospiech (PP) to low crystal and triclinic sample symmetry. The material chosen for emphasis is quartz which is of great tectonic importance in the earth's crust. Its textures also vary greatly in geological conditions. Together, the researchers plan to measure pole figures on deformed quartzites from different classical localities and prepare a catalog of ODFs with the PP method. Results should provide a more quantitative interpretation of quartz textures in terms of their geophysical deformation history. This project in geophysics fulfills the program objective of advancing scientific knowledge by enabling leading researchers in the United States and Poland to combine complementary efforts and capabilities in areas of strong mutual interest and competence in the field of basic scientific research on the basis of equality, reciprocity, and mutuality of benefit.
