Zhang（2014）关于柴达木盆地贝壳坝形成和时代的评论远远超出了我们的贝壳坝论文（Lai et al. 2014; Mischke et al. 2014），包括了关于中国其他一些湖泊盆地的问题。虽然我们不同意张教授对其他流域（如青海湖流域）的许多评论，但我们不能指望在这里全部解决，所以我们坚持几个要点。首先，我们解决有关贝壳坝的具体意见，包括：（1）贝壳坝沉积物，（2）地貌的历史和影响，（3）Corbicula贝壳作为一个主要的贝壳坝成分，（4）OSL年龄数据。其次，我们解决了什么是肯定的科学上更重要的，但尚未解决的问题的核心辩论，即相对可靠性的OSL与放射性碳测年的海岸线沉积物的范围从MIS 5到早期MIS 3。
Zhang’s (2014) comments on the formation and age of the Shell Bar in the Qaidam Basin go far beyond our specific Shell Bar papers (Lai et al. 2014; Mischke et al. 2014) and include questions about a number of other lake basins in China. Although we disagree with many of Zhang’s comments about these other basins (eg the Qinghai Lake Basin), we cannot hope to address them all here, so we stick to several main points. First, we address specific comments about the Shell Bar, including:(1) Shell Bar sediments,(2) geomorphological history and implications,(3) Corbicula shells as a major Shell Bar constituent, and (4) OSL age data. Second, we address what is surely the more scientifically important, and as yet unsettled issue at the core of the debate, ie the relative reliability of OSL versus radiocarbon dating for shoreline sediments in the range from MIS 5 to early MIS 3.
