| 摘 要： | 辽宁本溪晶花洞发育于中奥陶统马家沟组（O2m）中厚层白云质灰岩中，洞内碳酸钙沉积物具有白色、黄色、肉红色、浅蓝色和黑褐色等多种原生色彩。在洞穴考察的基础上，通过对围岩和洞穴碳酸钙沉积物X荧光分析以及显微镜薄片鉴定，认为洞穴中自色的次生化学沉积物主要由质纯的CaCO3形成；浅蓝色、黑褐色的形成则多由沉积物含有铜、锶和锰、锌所致；而黄色、红色则为不同环境下铁、锰等变价元素所产生。

| Abstract: | Jinghua Cave is developed in thick-bedded limestone of the Middle Ordovician Majiagou Formation in Benxi, Liaoning. Speleothems in the cave have many primary colors, such as white, yellow, red, blue and black. On the basis of research on the cave, X RF analysis and thin-section identification under the microscope have done. It is confirmed that the white color comes from pure CaCO3, blue and black from Cu, Sr, Mn and Zn components in the speleothems, yellow and red from some elements like Fe and Mn with different valence under different conditions. |
