成都市新都区新石器时代晚期土坑墓提取与保护

2008年1月，成都文物考古研究所与成都市新都区文物管理所在对一新石器时代晚期聚落遗址进行的考古发掘中，清理出土了二座竖穴土坑墓，其中M1墓葬人骨基本完整，具有较高的研究价值，但因年代久远和有害环境的影响，骨质已粉化，不便于直接提取人骨。为了有效地保护这一新石器时期人类骨骸，为后期的科学研究保存下这一珍贵的实物资料。决定采取套箱法对整座土坑墓进行提取的方式保护人骨，经过多方试验，确定采用A305黏结剂修复骨架裂纹，用GSA-102保护剂，B365作加固进行保护。经观察表明，本次土坑提取与保护取得了良好效果，并制定了一套科学的保护方案。该土坑墓的成功提取和科学保护，为今后在潮湿环境中的古遗址保护提供了可供借鉴的经验。
