Workshop Proposal: Comparison and Integration of Paleoelevation Measurement Approaches

目前正在利哈伊大学举办一个题为“古海拔测量方法的比较和综合”的讲习班，以便制定一种办法，解决使用各种古海拔代用指标（地貌学、裂变径迹和去顶、宇宙成因核素和暴露年龄、目的地盆地的地层学、古植物群、自生矿物的氧同位素、泡状玄武岩）确定的古海拔估计值之间的明显差异。讲习班的参加者正在通过以下方式朝着这一目标迈出第一步：（1）介绍每一种现有的代用品和古高程测量方法;（2）确定每一种技术的范围和局限性;（3）评估可能的地点和时间间隔，以便进行协调分析;（4）概述一项协调努力的攻击计划;以及（5）建立一组将由每个参与组产生的结果，以及结果的截止日期。分析方案，涉及研究区域（例如，科罗拉多高原、西藏等），特定的时间间隔（如全新世、始新世-渐新世等），与会者正在制定最低时间分辨率（例如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.
