Fossil data from Central Asia (Afghanistan, Uzbekistan, Pakistan, NW China, Mongolia, Altaids) indicate significant degree of palaeo-latitudinal variation in biogeographical patterns across the Palaeo-Tethys and its flanking shelves during Late Palaeozoic, but details of these patterns and implications for enhancing contemporaneous palaeogeographical models are virtually unknown. This project will analyse the biogeographical patterns of Late Palaeozoic brachiopod, coral, fusulinid faunas using advanced statistical methods, and integrate biogeographical signals with palaeomagnetic data to constrain models for the Late Palaeozoic geological evolution of Central Asia-a vast region that is known to bear enormous potential for natural resources but remains geologically little explored.

来自中亚（阿富汗、乌兹别克斯坦、巴基斯坦、中国西北部、蒙古、阿尔泰山脉）的化石数据表明，在晚古生代，古特提斯及其侧翼陆架的古地理模式存在显著的古纬度变化，但这些模式的细节以及对增强同时代古地理模式的影响几乎是未知的。该项目将使用先进的统计方法分析晚古生代腕足动物、珊瑚、fusulinid动物群的地理模式，并将地理信号与古地磁数据相结合，以约束中亚晚古生代地质演化的模型-这是一个已知具有巨大自然资源潜力但地质勘探仍然很少的广阔地区。
