摘　　要：本文采用显微激光拉曼光谱分析了开平碉楼灰雕和壁画黄色颜料碎片的原材料组成,通过分析发现:灰雕的主要成分是稻草杆(作为骨架材料),石灰(CaCO3),沙(石英Si O2)以及黄色颜料类胡萝卜素。壁画黄色颜料碎片的成分则是针铁矿(α-FeOOH)和CaSO4。这也说明开平碉楼在选材上,即使是在同一栋楼内,相同颜色的颜料使用的原材料也不一定相同。In this work, Raw Materials of the plaster sculpture and fresco Pigments in Kaiping Diaolou tower were analyzed by micro Raman spectroscopy. It was found that the compositions of the plaster sculpture were comprised of a mixture of rice straw which was used act as framework material, CaCO3, SiO2 and Carotenoid （yellow pigment）. The yellow pigment fragment of the fresco in Xulu tower was also identified as α-FeOOH and CaSO4. It is indicated that the raw materials of Kaiping Diaolou may be different even if the same colored pigment used in one tower.
