PIs will analyze Neogene climatic and depositional evolution of the eastern Basin and Range (US) by integrating paleoecologic, stratigraphic and seismic data from the Great Salt Lake. Source of material is Amoco and includes cores, cuttings, samples, and seismic lines. ıPIs have funding from TEctonics program for basin analysis aspects of project.! Primary objective is to test hypotheses of climate change recently proposed for Neogene of western North America by 1) documenting onset and development of cool, dry climate in Neogene, 2) developing chronology through radiometric dates on tephras and basalts, 3) producing detailed climate record from a single region, for a time now known only from overlapping segments from diverse deposits. They will also a) develop a chronology for Neogene evolution of vegetation in the Great Basin, b) produce Neogene paleolimnologic study of GSL, c) study onset and evolution of glacial/interglacial climatic cycles.

PI将分析新近纪气候和沉积演化 东部盆地和山脉（美国），通过整合古生态， 大盐湖的地层和地震数据。 源 的材料是阿莫科，包括核心，岩屑，样品， 地震线 ıPI获得了盆地TEctonics计划的资助 项目分析方面。！ 主要目的是测试 新近提出晚第三纪气候变化假说， 北美西部通过1）记录的发病和发展 晚第三纪气候凉爽、干燥; 火山岩和玄武岩的放射性测年，3） 一个地区的气候记录，一段时间以来， 不同沉积物的重叠部分。 他们也将（a） 发展一个新第三纪植被演化年表， 大盆地，B）产生GSL的新近纪古湖泊学研究，c） 研究冰期/间冰期气候循环的开始和演变。
