9506470 Burgmann This project will characterize the important vertical motions associated with the San Andreas transform fault system in the San Francisco Bay area. Current estimates of the amount of shortening and uplift associated with the fault in the San Francisco Bay area vary by up to an order of magnitude. An integrated study of fission track, geomorphic, geodetic and fault system modeling analysis will quantify the intense recent contraction and uplift. The data will be used to assess the importance of zones of intense vertical motions along faults and will be used to calibrate qualitative geomorphic indicators of uplift and fault movement with quantitative uplift magnitudes derived from fission track data and measured historic uplift patterns. The results will be of importance to all tectonically active regions of the world.

该项目将描述与旧金山湾区圣安德烈亚斯变换断层系统相关的重要垂直运动。目前对与旧金山湾区断层有关的缩短和隆起量的估计相差可达一个数量级。综合研究裂变径迹、地貌、大地测量和断层系统建模分析将量化近期强烈的收缩和隆升。这些数据将用于评估沿断层剧烈垂直运动带的重要性，并将用于校准抬升和断层运动的定性地貌指标，根据裂变径迹数据和测量的历史抬升模式得出定量抬升幅度。研究结果对世界上所有构造活跃地区都具有重要意义。
