通过对西藏昌都热底垄石棺墓人骨年代的研究 ,认为热底垄石棺墓的年代应不早于卡若遗址 ,不晚于香贝石棺墓 ,人骨14 C年代应该在距今 4 0 0 0～ 2 4 0 0a之间。并论述了人骨测年的方法以及在野外采样的注意事项。在定年方法上 ,提出对同一样品采用不同的测定技术进行交叉验证 ,以提高数据的可信度研究方法
Through the study of the human bone age in the hot-bottom dull coffin in Changdu, Tibet, it is believed that the age of the hot-bottom dune coffin should not be earlier than that of the Karuowan site and no later than that of the Shabelian sarcophagus. The human bone age should be between 40,000 years ago ~ 2 4 0 0a between. And discusses the method of human bone dating and sampling in the field of precautions. In the method of dating, it is proposed to use different measurement techniques for cross-validation of the same sample to improve the credibility of the data.
