0549748ClarkThe 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.

0549748 Clark本项目的目标是研究青藏高原东北部地形、形变、大气环流和气候之间可能的反馈。该提案旨在了解高原隆升的时间和空间格局，并据此推断隆升的机制（密度下降和/或通道流动），并确定隆升对地方、区域和全球尺度气候变化的影响。为此，PI将采用各种方法和人员：Molnar：项目协调员，分析GPS，重力和地震数据，变形和大气相互作用建模;伯班克：磁性地层学，sed。构造、锆石U-Pb定年、构造和平衡截面;Clark：构造和平衡截面、U-Th/He定年、重力和地震折射数据分析;Garzione：碎屑锆石U-Pb、盆地沉积物氧和碳同位素、构造和平衡截面; Kirby：构造和平衡截面、U-Th/He定年子集;法利：U-Th/He定年; Roe：大气建模（利用氧气数据）;中国合作者：磁性地层学、磷灰石裂变轨迹、提供全球定位系统和地震数据。
