The long-term history of the Asian monsoon climate is important for a better understanding of regional- to global-scale climate change during the late Neogene, but poorly documented. We propose a multidisciplinary study of -1 km thick late Miocene to Pleistocene (ca. 7-1 Ma?) lacustrine deposits exposed in the Zada basin, SW Tibet, to establish a medium- to highresolution long-term climate record for that region. The present proposal will build and expand upon the results of an ongoing pilot study, during which we established a detailed stratigraphic and sedimentologic framework, and carried out initial sampling for sediment-petrographic work, geochronologic work, and the evaluation of a variety of different potential proxy materials for the reconstruction of climatic and ecologic conditions in the Zada Basin during Late Miocene to Pleistocene time.

亚洲季风气候的长期历史对于更好地理解新近纪晚期区域到全球尺度的气候变化非常重要，但记录很少。我们提出了一个多学科的研究-1公里厚的晚中新世更新世（约。7-1妈？）在西藏西南部扎达盆地暴露的湖相沉积，建立该地区的中到高分辨率的长期气候记录。目前的建议将建立和扩大正在进行的试点研究的结果，在此期间，我们建立了一个详细的地层和沉积框架，并进行了初步采样的沉积岩石学工作，地质年代学工作，并评估各种不同的潜在的代用材料重建的气候和生态条件在扎达盆地晚中新世至更新世的时间。
