We show that Zhang and Li's sedimentological model for the Chusang travertine neglects the three-dimensional information from multiple outcrops and that their optically stimulated luminescence (OSL) age of about 20,000 years for the human imprints is untenable. We highlight the robustness of our chronology and explore reasons why Zhang and Li's OSL age is a gross overestimation of the real depositional age of the imprinted travertine.
我们表明，张莉的楚桑钙华沉积学模型忽略了多个露头的三维信息，而且他们对人类足迹的光释光（OSL）年龄约 2 万年也是站不住脚的。我们强调了我们测年结果的可靠性，并探讨了为什么张莉的 OSL 年龄严重高估了足迹钙华的实际沉积年龄。
