Workshop Proposal: Comparison and Integration of Paleoelevation Measurement Approaches

一个题为“古海拔测量方法的比较与整合”的研讨会正在里海大学举行，目的是开发一种方法，解决利用各种古海拔代用物（地貌学、裂变径迹和拆顶、宇宙成因核素和暴露年龄、目的地盆地地层、古植物区系、自生矿物的氧同位素、泡状玄武岩）确定的古海拔估计之间的明显差异。研讨会的参与者通过以下方式迈出了第一步：(1)介绍了现有的古高程测量方法；(2)确定每种技术的范围和限制；(3)评估协同分析的潜在地点和时间间隔；（四）制定协同作战计划；(5)建立一组由每个参与小组产生的结果，以及结果的截止日期。与会者正在制定一个分析方案，包括一个研究区域（如科罗拉多高原、西藏等）、一个特定的时间间隔（如全新世、始新世-渐新世等）和一个最低时间分辨率（如1000万年10个数据点）。

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.
