中文摘要
韦斯努斯基0086667大盆地省是世界上最大、暴露最好、最容易进入的大陆伸展区,占北美-太平洋板块边界运动的25%。 由其他人操作的全球定位卫星GPS测量开始提供整个盆地应变积累的情况。 正是应变释放的过程导致了我们今天所观察到的盆地和山脉的结构、自然地理和地震的时空模式。 应变积累和应变释放的措施,需要了解盆地和山脉地区的变形动力学和演化。 新构造和古地震技术正被应用于活动断层,这些活动断层将与现有GPS断面大致平行并毗邻内华达州I-80走廊的主要山脉前缘连接起来。 古地震研究旨在量化并比较整个晚第四纪断层位移的历史和演变与当今观察到的应变累积模式。
英文摘要
Wesnousky0086667The Great Basin province is the largest, best-exposed, and most accessible region of continental extension in the world and accounts for up to 25% of the motion across the North American - Pacfic plate boundary. Global Positioning Satellite GPS measurements operated by others are beginning to provide a picture of strain accumulation across the Basin. It is the process of strain release that results in the structure, physiography, and the spatial and temporal pattern of earthquakes that define the Basin and Range as we observe it today. Measures of both strain accumulation and strain release are required to understand the dynamics and evolution of deformation in the Basin and Range province. Neotectonic and paleoseismic techniques are being applied to active faults that bound major mountain fronts that sit subparallel to the existing GPS transects and adjacent to the I-80 corridor of Nevada. The paleoseismic studies are designed to quantify and compare the history and evolution of fault displacement through the late Quaternary to the pattern of strain accumulation that is being observed today.
