EAR-PF: The Role of Diking in the Evolution of Continental Rift Systems

Patricia Gregg博士被授予NSF地球科学博士后奖学金，在哥伦比亚大学Lamont-Doherty地球天文台开展研究和教育计划。格雷格博士将研究岩浆注入和岩墙传播对沿裂谷地带的大陆解体所起的作用。研究目标将通过检查来自当地地震台站阵列、GPS网络和InSAR形变数据来实现。这些数据将被整合到计算机模型中，这些模型考虑了随着地壳压力和深度的增加而发生的温度和岩石强度等变化。这次调查的结果有助于更好地了解裂谷系统，并将有助于评估地震和火山喷发等危险。此外，格雷格博士将与本科生和研究生合作，帮助他们在研究项目中提供指导。这项调查将有助于更大规模的国际努力。

Dr. Patricia Gregg is awarded an NSF Earth Science Postdoctoral Fellowship to carry out a program of research and education at Lamont-Doherty Earth Observatory, Columbia University. Dr. Gregg will investigate the role that magma injection and dike propagation have on the break up of continents along rift zones. The research goals will be accomplished by examining data from local arrays of seismic stations, GPS networks, and InSAR deformation data. These data will be integrated in computer models that take into account changes like temperature and strength of the rocks with increasing pressure and depth into the crust. The results from this investigation contribute to better understanding of the rift systems and they will help in the assessment of hazards like earthquakes and volcanic eruptions. In addition, Dr. Gregg will work with undergraduate and graduate students in assisting with their mentoring in research projects. This investigation will contribute to a larger international effort.
