在某些环境条件下，沉积后成岩作用造成的骨胶原损失会严重减少特定考古遗址中适合稳定同位素分析或放射性碳测年的骨骼数量。这项研究检查了来自英格兰南部 12 个考古遗址的近 300 块骨头，这些骨头的保存状况较差或存在差异，试图找出一种或多种预筛选技术，为放射性碳测年提供合适的胶原蛋白保存。最可靠的方法是全骨粉末的氮百分比 (%N)，该方法有 84% 的机会成功预测骨头是否会产生足够（即 >1% 重量）的胶原蛋白用于约会。 (C) 2009 Elsevier Ltd. 保留所有权利。
Under certain environmental conditions, post-depositional diagenetic loss of bone collagen can severely reduce the number of bones from a particular archaeological site that are suitable for stable isotopic analysis or radiocarbon dating. This study examined nearly 300 bones from 12 archaeological sites across southern England known to yield poor or variable preservation to try to identify one, or more, pre-screening technique(s) that would indicate suitable collagen preservation for radiocarbon dating. The most reliable method was shown to be the percent nitrogen (%N) of whole bone powder, which has an 84% chance of successfully predicting whether or not a bone will yield sufficient (i.e. >1% weight) collagen for dating.
