本研究分为两个部分：（1）对青少年的研究 保加利亚的拉张历史;（2）流体的应用 下地壳流动问题的动力学理论 大陆变形 保加利亚的组成部分 程序包括：汇编现有的数据， 与年轻人有关的特征的结构、年龄、地层等 保加利亚的伸展;伸展的区域相关性 沿希腊海沟系统沿着的同时代事件; 年轻人的重力和地形数据的定量分析 伸展特征 这部分研究的目的是 是为了更好地理解俯冲和 上部区域变形驱动力 岩石圈 下地壳流动问题 岩石圈变形将通过应用 简单通道（或片）流到简单两个的变化， 变形岩石圈三维模型 最终目的是更好地了解地壳的耦合 以及大陆变形过程中的地幔运动。 该项目结合了试图了解基本的 保加利亚的第三次演变，试图获得更好的 下地壳流动的理论处理。 它还 促进VPW计划目标，为以下方面提供机会： 女性在科学或工程领域的职业发展 通过研究，并鼓励其他妇女追求 在这些领域的职业生涯，通过调查人员的增强 在主办校园中树立榜样。 在这 第二个项目的拟议活动， 目标包括：举办一系列客座讲座， 为妇女建立每周研讨会/支助小组 研究生（和博士后研究员）和咨询 在一个目前有 没有女教师。

This research consists of two parts: (1) a study of the young extensional history of Bulgaria; and (2) application of fluid dynamic theory to the problem of lower crustal flow during continental deformation. The Bulgarian component of the program consists of: compilation of existing data on the structure, age, stratigraphy, etc. of features related to young extension in Bulgaria; regional correlation of extensional events with coeval events along the Hellenic trench system; and quantitative analysis gravity and topography data across young extensional features. The goal of this portion of the study is to better understand the relationship of subduction and its driving forces to regional deformation in the upper lithosphere. The problem of lower crustal flow during lithospheric deformation will be addressed by application of a variation of simple channel (or sheet) flow to simple two and three dimensional models of the deforming lithosphere with the ultimate goal of better understanding the coupling of crustal and mantle motions during continental deformation. The project combines an attempt to understand the basic tertiary evolutions of Bulgaria with an attempt to get a better theoretical handle on flow in the lower crust. It also furthers VPW program objectives to provide opportunities for women to advance their careers in science or engineering through research, and to encourage other women to pursue careers in these areas through the investigators' enhanced visibility as role models on the host campuses. In this project, the proposed activities which contribute to the second objective include: presentation of a series of guest lectures, establishment of a weekly seminar/support group for female graduate students (and post-doctoral fellows), and counseling of female students in a department where there are currently no female faculty.
