This proposal applies for 18 months final funding of a PhD position within a research project in Spitsbergen that is carried out as a cooperation between the Universität Bremen, the Federal Institute for Geosciences and Natural Resources (BGR), and other partners. The project applies apatite fission track (FT) and (U-Th-Sm)/He thermochronology, clay mineral and vitrinite reflectance analysis for reconstructing the thermal history of basement rocks and sedimentary cover. The principle aim of this research is to investigate the Phanerozoic crustal dynamics of northern and central Spitsbergen, its implications on the opening of the Atlantic and consequences on regional long-term climate evolution. Four specific objectives are:1) Passive margin evolution of Svalbard2) Late Mesozoic and Cenozoic regional tectonic history3) Thermal evolution of the Central Tertiary Basin4) Coupling of Neogene climate change and tectonics, and long-term landscape evolution.

该提案适用于斯匹次卑尔根岛研究项目中博士学位的18个月最终资助，该项目是作为不莱梅大学，联邦地球科学与自然资源研究所（BGR）和其他合作伙伴之间的合作进行的。该项目应用磷灰石裂变径迹（FT）和（U-Th-Sm）/He热年代学、粘土矿物和镜质体反射率分析，重建基底岩石和沉积盖层的热历史。这项研究的主要目的是调查北方和中部斯匹次卑尔根群岛的中生代地壳动力学，其对大西洋开放的影响和对区域长期气候演变的后果。四个具体目标是：1）Svalbard被动边缘演化2）晚中生代和新生代区域构造历史3）中第三纪盆地的热演化4）新近纪气候变化与构造的耦合，以及长期的景观演化。
