ABSTRACT

The aim of this study is to assign the provenance of Roman marble statues and assess their condition in order to use this information as a guideline for their future conservation treatments. Several analytical methods were applied to investigate the provenance of the statues including petrography, X-ray diffraction, and mass spectrometry. The deterioration level of the statues was assessed by non-destructive ultrasonic velocity measurements. The provenance investigation showed that four statues were most probably made of the dolomitic marble quarried from Thasos Island, Greece and one statue was made of the Proconnesus marble quarried from Marmara Island, Turkey. The condition assessment study revealed that the statutes are still in a good condition, although they exhibit weathering in the form of increasing porosity. Consequently, suitable conservation measures and recommendations for preserving the marble statues and preventing future damage were proposed. In general, the ultrasonic technique proved to be effective for assessing marble condition and identifying and prioritizing required conservation work in a fast, reliable, and non-destructive way.

摘要

本研究的目的是确定罗马大理石雕像的出处并评估它们的状况，以便将这些信息用作未来保护处理的指南。应用了几种分析方法来研究雕像的来源，包括岩相学、X 射线衍射和质谱法。通过无损超声波速度测量来评估雕像的退化程度。出处调查显示，四尊雕像最有可能由希腊萨索斯岛开采的白云岩大理石制成，一尊雕像由土耳其马尔马拉岛开采的 Proconnesus 大理石制成。状况评估研究表明，法规仍然处于良好状态，尽管它们以孔隙率增加的形式表现出风化。最后，提出了保护大理石雕像和防止未来损坏的适当保护措施和建议。总的来说，超声波技术被证明可以有效地以快速、可靠和无损的方式评估大理石状况，并确定所需的保护工作并确定其优先级。
