A workshop entitled "Comparison and Integration of Paleoelevation Measurement Approaches" is being held at Lehigh University in order to develop a means to resolve the apparent discrepancy between paleoelevation estimates determined using various proxies for paleoelevation (geomorphology, fission tracks and unroofing, cosmogenic nuclides and exposure ages, stratigraphy in destination basins, paleoflora, oxygen-isotopes of authigenic minerals, vesicular basalts). Workshop participants are taking the first step toward this by: (1) presenting each of the existing proxies and approaches to paleoelevation measurement; (2) identifying the scope and limitations of each technique; (3) assessing potential sites and time intervals for coordinated analysis; (4) outlining a plan of attack for a coordinated effort; and (5) establishing a set of results to be generated by each participating group, and a deadline for results. A protocol for analysis, involving a study region (e.g. Colorado Plateau, Tibet, etc.), a specific time interval (e.g. Holocene, Eocene-Oligocene, etc.), and a minimum temporal resolution (e.g. 10 data points in 10 million years) is being developed by the conferees.

一个题为“古高程测量方法的比较和整合”的研讨会正在里哈伊大学举行，目的是开发一种方法来解决使用各种古高程代理（地貌、裂变径迹和屋顶、宇宙成因核素和暴露）确定的古高程估计之间的明显差异。年龄、目的地盆地地层、古植物群、自生矿物的氧同位素、囊泡玄武岩）。研讨会参与者通过以下方式迈出了第一步：(1) 介绍每个现有的古海拔测量代理和方法； (2) 确定每种技术的范围和局限性； (3) 评估协调分析的潜在地点和时间间隔； （四）制定协同攻坚计划； (5) 确定每个参与小组要产生的一组结果以及结果的截止日期。分析协议，涉及研究区域（例如科罗拉多高原、西藏等）、特定时间间隔（例如全新世、始新世-渐新世等）和最小时间分辨率（例如1000万年中的10个数据点） ）正在由与会者制定。
