瘦长红珊瑚的微尺度结构特征

Microscale Structure Characteristics of Corallium Elatius

采用扫描电子显微镜对经脱钙处理的瘦长红珊瑚样品的表面微形貌进行了研究,观察了样品表面的形貌特征,分析了其方解石晶体的排列方式和大小。结果显示,在瘦长红珊瑚样品纵向外表面的"脊-槽"结构上分布有由方解石晶体螺旋堆积而成的突起;其横截面由围绕不同轴心成层螺旋生长的柱纤状方解石晶体规则排布而成;分布于方解石组成的骨骼颗粒间并形成多级有机质网脉说明,瘦长红珊瑚的矿物相与其有机基质相关。

The surface microtopography of Corallium elatius sample by decalcification is studied by using the scanning electron microscope （SEM）, whose characteristics are observed, and the arrangement model and size of the calcite crystal are analysed. The results show that the protuberances distributed on the ＂ridge-trough＂structure are formed by spiral accumulation of calcite from the external surface of the Corallium elatius samples from longi- tudinal section. The cross sections of the Corallium elatius samples are distributed by numerous calcite crystal being spiral growth surrounding the different axis centers. Through the multi-level organic matrix mesh in the bone particles, it indicates that the mineral phase is rebated to the organic matrix in Corallium elatius.
