    摘要:

    科学钻探岩芯是地球科学研究的宝贵实物资料,它直接反映了地球深部的结构、物质组成和地质历史,对于地质学、地球物理学、地球化学、材料科学、信息科学等多学科领域的研究均具有相当的重要性和独特价值。本研究聚焦于科学钻探岩芯的低损耗成分测试和物性测量方法的探索与实践,旨在通过技术创新与流程优化,以实现对珍贵科钻岩芯资源的保护与高效利用。笔者等首先从样品布设与采集方案的科学设计入手,对取样位置与数量进行系统规划,确保数据的代表性与可靠性。随后详细阐述了物性测量取样流程,针对不同规格样品开展波速、密度、磁性和电性测量,为深部地质特征研究提供了基础物性数据。在岩芯化学成分分析方面,提出了低损耗测试策略,包括优先确保单次分析用量、选择性分析微量元素以及特殊岩芯状态(如松散或碎裂)的灵活处理方法。此外,研究还强调了样品归位及余样保存的重要性,确保岩芯资源的可追溯性与可持续利用。通过项目实施,笔者等提出的“科学钻探岩芯低损耗成分和物性测量”工作方法已初步验证其可行性与应用效果,为科学钻探岩芯的保护与高效利用提供了技术支撑与实践范例。

    Abstract:

    Scientific drilling cores are valuable physical materials for earth science research. They directly reflect the deep structure, material composition, and geological history of the Earth. These cores hold considerable importance and unique value for research in multiple disciplines including geology, geophysics, geochemistry, materials science, and information science. This study aims to explore and practice methods for low- loss chemical composition analysis and physical property measurement of scientific drilling cores to achieve the protection and efficient utilization of precious scientific drilling core resources. The paper proposes a scientific plan for sample layout and collection, then elaborates on the sampling process for physical property measurements, conducting wave speed, density, magnetic, and electrical measurements on different specifications of samples. For the chemical composition analysis of cores, a low- loss testing strategy is proposed, including ensuring single- analysis dosage, selectively analyzing trace elements, and handling special cases. Finally, the importance of sample repositioning and preservation of surplus samples is emphasized. The "low- loss chemical composition analysis and physical property measurement" method for scientific drilling cores proposed in this paper has been practiced during project implementation and has achieved preliminary application results. It holds significant importance for promoting the protection and efficient use of scientific drilling cores.
