0507730MolnarThe goal of this project is to study the possible feedback between topography, deformation, atmospheric circulation and climate in the NE portion of the Tibetan plateau. The proposal seeks to understand the timing and spatial pattern of plateau uplift and from this, infer the mechanism of uplift (density foundering and/or channel flow) and determine what effect, if any, the uplift had on climate change at local, regional and global scales. To do this, the PIs will employ a variety of methods and personnel: Molnar: project coordinator, analysis of GPS, gravity and seismic data, modeling of deformation and atmospheric interactions; Burbank: magnetostratigraphy, sed. structures, U-Pb dating of zircons, structures and balanced cross sections ;Clark: structures and balanced cross sections, U-Th/He dating, analysis of gravity and seismic refraction data ;Garzione: U-Pb detrital zircons, oxygen and carbon isotopes of basin sediments, structures and balanced cross sections; Kirby: structures and balanced cross sections, subset of U-Th/He dating;Farley: U-Th/He dating; Roe: atmospheric modeling (utilizing oxygen data); Chinese collaborators: magnetostratigraphy, apatite fission track, provision of GPS and seismic data.

这个项目的目标是研究青藏高原东北部地形、变形、大气环流和气候之间可能的反馈。该提案试图了解高原隆起的时间和空间模式，并由此推断隆起的机制(密度下降和/或河道流动)，并确定隆起对地方、区域和全球范围气候变化的影响。为此，PIS将采用各种方法和人员：Molnar：项目协调员，分析全球定位系统、重力和地震数据，建立形变和大气相互作用的模型；Burbank：磁性地层学、SED。Kirby：构造和平衡剖面U-Th/He定年；Clark：构造和平衡剖面U-Th/He定年，重力和地震折射数据分析；Garzione：盆地沉积物、构造和平衡剖面的U-Pb碎屑锆石、氧和碳同位素；Kirby：构造和平衡剖面，U-Th/He定年子集；Farley：U-Th/He定年；ROE：大气模拟(利用氧气数据)；中国合作者：磁地层学、磷灰石裂变径迹、提供全球定位系统和地震数据。
